La Paz Whale Shark Swims · 3 hours

Check availability →The rules around what you can carry into the water with whale sharks in La Paz are stricter than most travelers expect, and they are written into federal regulation, not operator preference. Here is the full packing picture: what the norm requires, what the bay's water temperatures demand, and what the listings themselves leave out.
Short answer
Bring a wetsuit or life vest (one is mandatory), biodegradable sunscreen only, a towel, warm layers, motion-sickness remedy taken before boarding, and cash for the crew. Leave the selfie stick, flash photography and motorised devices behind: NOM-171 bans all three. Sea temperatures of 20 to 24 C in season make a 3 mm shorty to 5 mm full wetsuit the standard advice.
A whale shark swim in La Paz is one of the few wildlife activities where the packing list is partly set by federal law. The norm that governs the activity, NOM-171-SEMARNAT-2018, specifies what a swimmer may wear, what kind of sunscreen is allowed in the water and which camera accessories are prohibited outright. Operators enforce these rules because PROFEPA and CONANP inspect boats in the refuge, so an item you bring in error can cost you water time rather than just comfort. This guide works through the list item by item, using the regulation, the verified sea-temperature record for the bay and the exclusion lines printed on the actual tour listings, so nothing here is guesswork. If the strict gear rules make you wonder what the actual risk in the water is, our look at whether a whale shark has ever attacked a person explains what these regulations are really protecting against.
The broader season picture matters too. The 2026-27 season runs 1 October 2026 to 30 April 2027 under a SEMARNAT aviso that authorizes 112 boats and requires at least 6 sharks in the swim zone before any trip operates. Water temperature and air temperature shift across those months, which changes what you wear on the boat as much as in the water. For the month-by-month detail, see the season guide for La Paz.
Pack a wetsuit or a life vest (the regulation requires one of the two), biodegradable sunscreen only, a towel, a warm dry layer for the ride back, seasickness remedy taken before departure, and cash in pesos for the crew and dockside costs. Leave selfie sticks, flash gear and motorised devices at the hotel: all three are banned in the water.

Check availability →That is the short version. The slightly longer version is that most of the serious packing decisions fall into three groups: what the law says, what the water temperature says, and what your specific tour listing says it already provides versus expects you to carry. Many shared swims in La Paz include wetsuits and snorkel gear in the ticket price, which removes the single heaviest item from your bag. The marine-biologist small group run by MeXplore, from $178 per person, lists wetsuits, snorkel equipment, federal permits and even GoPro photos among its inclusions. The budget end of the roster varies more, so the exclusion line on each listing deserves a read before you pack.

One planning note that surprises visitors: towels are the most commonly excluded item on La Paz listings. MeXplore, Salty Life in Baja, Eco Migrations, La Paz Whale Sharks VIP Tours and La Paz Explorer all list towels under exclusions on their roster lines. A quick-dry towel weighs almost nothing and solves the problem entirely.
| Item | Status on most La Paz listings | Rule source |
|---|---|---|
| Wetsuit or life vest | Often included; one is mandatory in the water | NOM-171-SEMARNAT-2018 |
| Snorkel mask, snorkel, fins | Included on nearly every shared listing | Listing inclusions |
| Biodegradable sunscreen | Sometimes included (premium listing), otherwise bring your own | NOM-171 |
| Towel | Excluded on at least five major listings | Listing exclusions |
| Warm dry layer | Excluded; bring your own | Listing exclusions |
| Gratuities for crew | Excluded; bring cash | Listing exclusions |
If you are still choosing between operators, the guide to choosing a swim compares group sizes, prices and inclusions across the roster.
Yes in practice, and in law you need at least a wetsuit or a life vest. NOM-171 requires every swimmer in the water with whale sharks to wear one or the other. For Sea of Cortez temperatures of 20 to 24 C during the season, operators advise a 3 mm shorty at minimum and a 5 mm full suit for the coldest mornings, roughly December through March. If you feel steadier about your gear than your stroke, our guide on whether weak swimmers can still snorkel with whale sharks explains what the experience actually demands in the water.
The water in Bahia de La Paz is not tropical-warm at the time of year whale sharks visit. Satellite readings averaged by month put the sea at about 20 C in January, dipping to just above 19 C in February and back to about 20 C in March, then climbing through 21 C in April toward 24 C in May. October sits near 29 C, November near 26 C and December near 22 C. You can check the full monthly series at seatemperature.org's La Paz page. What that means in clothing terms: a late-season or mid-winter swim without a wetsuit is a short, cold experience, and several hours of repeated drops into the water drain body heat even for strong swimmers.
The good news is that you almost never need to bring your own. Wetsuits appear in the inclusion lists of the MeXplore small group, the Tuna Tuna Tours small group, the Eco Migrations adventure (a 2 to 3 mm full suit, listed specifically), Baja Wild Adventures, Desértica Baja Sur, The Hook Experiences and several others. Where a listing does not mention a wetsuit, it will mention a life vest or leave the item open, so read the line before assuming. If you run cold or swim in February, a neoprene hood or a thicker suit is a fair question to ask the operator when booking.
Air temperature matters too, because you spend more time on the boat than in the water. Mean daily highs run from about 25 C in January to 34 C in October, but the mornings when whale shark shifts depart are cooler, and a wet swimmer in wind loses heat fast. A fleece or sweatshirt for the ride back is standard local advice; MeXplore's exclusion line even names a sweatshirt among things to bring yourself. The full climate picture is in the La Paz weather by month guide.
Only biodegradable sunscreen, and only applied before you enter the water: that is the NOM-171 rule for the whole whale shark refuge. Conventional chemical sunscreen is not permitted on the swim. Reef-safe mineral stick, a rash guard and a hat are the practical alternatives for the boat ride.
The refuge around the bay, the Area de Refugio Bahia de La Paz decreed in November 2018 across 22,749 hectares, exists specifically to protect this species, which is listed as threatened under Mexican law. The sunscreen rule is one of the small ways a swimmer interacts with that protection. The practical packing move is a twin approach: a rash guard for the boat and surface intervals, and biodegradable sunscreen only where skin is exposed. One premium listing on the roster, the Intimate Eco-Friendly Whale Shark Encounter from La Paz Whale Sharks VIP Tours at from $295 per person, includes biodegradable SPF 50 sunscreen in the ticket, which is the only roster line that does.
| Item | Allowed in the whale shark zone | Notes |
|---|---|---|
| Biodegradable sunscreen | Yes, before entering the water | NOM-171 requirement |
| Conventional chemical sunscreen | No | Prohibited for the swim |
| Rash guard | Yes | A common sunscreen substitute |
| Life vest or wetsuit | Required, one of the two | NOM-171 |
| Selfie stick | No | Explicitly prohibited |
| Flash or artificial light | No | Explicitly prohibited |
Camera rules deserve their own sentence because people lose water time over them. Photos are allowed, but no selfie sticks, no flash and no artificial lighting, and swimmers must keep the regulation distance of 2 m from the head and sides of a shark and 3 m from its tail. If your camera setup needs a rig, it belongs on the boat. Several operators, including MeXplore and Tuna Tuna Tours, include GoPro photos and video of the tour in the price, which is worth weighing against hauling your own housing.
The marine-biologist small group from MeXplore, at from $178 per person and 4.9 from 649 reviews, is the site's featured swim precisely because its inclusion list covers the awkward items: wetsuits, gear, permits, insurance and photos. You can see the full listing details here alongside Check availability.
That Sunrider listing at from $110 per person is the cheapest firm-priced shared swim on the roster, and its exclusion line (dock fee, conservation fee, gratuities) is exactly why the cash question below matters.
For a combo day that adds Balandra beach or the Espiritu Santo islands, pack for two climates in one bag: the same swim kit, plus beach shoes, a dry change of clothes, sun protection for long surface time and the small park fees. Balandra charges a reported MXN 120 per person and the Espiritu Santo park wristband a reported MXN 225 per person per day; confirm both on the day.
Combo tours run six to nine hours, against two to four for a pure whale shark swim, so the day looks different. The Tuna Tuna Tours combo (whale sharks, sea lions and Balandra, 6 hours, from $234 per person, 5.0 from 113 reviews) includes lunch, wetsuits and drinks; the MeXplore version at the same price includes food, permits and photos. The Baja Sur Tours picnic day at Espiritu Santo, from $278 per person for 9 hours, adds local beer to its inclusions. What none of them hand you is beach footwear, a dry bag or a second warm layer for the return leg, and those three items earn their place on long days. The full index of guides sits on La Paz Whale Shark Tours.

Two access details shape the packing. Balandra admits visitors in two daily turns, 08:00 to 12:00 and 13:00 to 17:00, capped at 450 people per turn, per the La Paz municipal tourism pages at turismo.lapaz.gob.mx. And the sea lion colony at Los Islotes closes to swimmers entirely from 1 June to 31 August for the reproductive season, reopening about 1 September, so a combo that includes sea lions is a September-to-May product. The full picture is in the Espiritu Santo island tour guide and the sea lion swimming guide.
| Combo listing | Duration | Price | What to add to your bag |
|---|---|---|---|
| Tuna Tuna Tours whale shark, sea lion and Balandra | 6 hours | from $234 per person | Beach shoes, dry layer, cash for crew |
| MeXplore whale sharks and sea lions with Balandra lunch | 6 hours | from $234 per person | Towel, sunscreen, sweatshirt (listed exclusions) |
| Baja Sur Tours Espiritu Santo picnic | 9 hours | from $278 per person | Towel, hat, sea-sickness remedy for the long crossing |
| La Paz Tiki Tours 8-hour small group | 8 hours | from $345 per person | Reef-safe sunscreen (excluded), towel |
Towels, gratuities and hotel transport are the three exclusions that repeat across the La Paz roster. Several listings also exclude dock or conservation fees, photos or biodegradable sunscreen. The rule is simple: an exclusion on a listing is a packing instruction, so read that line on your own booking before deciding what to buy or leave home.
Because the same operator can run several distinct listings with different inclusions, never assume. The Sunrider Tours swim at from $110 per person excludes the dock fee and the conservation fee on top of gratuities; the Punta Baja Tours listing at from $122 includes lunch and drinks but states no star rating from its 13 reviews, too few for a rating claim; the premium VIP encounter includes sunscreen but excludes transport and tips. The pattern is consistent enough to plan around.
| Listing (operator) | Price | Towel excluded | Gratuities excluded | Transport excluded |
|---|---|---|---|---|
| MeXplore small group | from $178 per person | Yes | Yes | Yes |
| Eco Migrations adventure | from $194 per person | Yes | Yes | Not stated |
| Baja Wild Adventures | from $159 per person | Not stated | Not stated | Not stated |
| La Paz Whale Sharks VIP | from $295 per person | Yes | Yes | Yes |
| Sunrider Tours swim | from $110 per person | Not stated | Yes | Not stated |
| La Paz Explorer | from $128 per person | Yes | Yes | Not stated |

The deeper context for what a listing can and cannot promise is regulatory. Swims happen under NOM-171, and the swim rules guide walks through the full set: 5 swimmers per guide, 30 minutes per boat per shark, approach speeds and the behaviours that end an encounter. The norm itself is published on the official federal gazette page.
That premium encounter, 5.0 from 422 reviews, is the listing to pick when you want the awkward packing items solved by someone else: fees, gear, drinks and biodegradable SPF 50 are all in the price of from $295 per person.
Take a motion-sickness remedy before boarding, not after, because boat time to the swim zone runs 20 to 40 minutes by operator report and shifts mean repeated drops and pickups. Carry cash for gratuities, and on some listings for dock or conservation fees. Gratuities appear as an exclusion on most La Paz listings, which means they are expected and not collected by card.
The bay is usually gentle, but a whale shark swim is not a smooth-boat experience: the boat idles, turns, holds station and repositions constantly while groups rotate through the water. Anyone prone to motion sickness should dose an hour before departure, stay on deck, watch the horizon and go easy on a heavy breakfast. The four daily shifts authorized by the aviso cluster around morning and midday slots, and operators typically confirm the exact time the evening before.

Cash planning is straightforward. This site does not publish tipping percentages, and none are verified for La Paz boat crews, so treat gratuity as a personal decision and bring small peso notes so you are not rounding a bill you cannot split. What can be stated from the roster: gratuities are listed as excluded on the MeXplore, Eco Migrations, Sunrider, VIP, La Paz Explorer, The Hook, Tuna Tuna combo and several other listings. Dock and conservation fees are named as excluded on the Sunrider line specifically, so budget extra cash there. For the money picture on tickets themselves, the cost guide breaks down every price on the roster.
Beyond cash and seasickness, three small items earn their slot: a dry bag for phone and documents left on board, sunglasses, and a refillable water bottle, since boats carry limited supplies and the Alonso Tours listing notably serves purified water from a container rather than bottles.
La Paz Whale Shark Swims · 5 - 5.5 hours
New listing with few reviews so far · From $174
Check availability →That Orza Tours small-group listing, from $174 per person for about five and a half hours, spells out its inclusions in detail: gear, life jacket, permits, boat transport and water, with hotel pickup and gratuities as the exclusions to plan around.
No special swim gear, but a longer day's kit: the three Los Cabos listings run 7 to 10 hours door to door, so add breakfast planning, motion-sickness cover for the road and sea legs of the drive, and the same towel and cash basics. The Cabo Adventures day trip includes hotel pickup, lunch, wetsuits and gear in its from $259 per person price.
The Los Cabos products are day trips that drive to La Paz and then board local boats; no roster swim departs from Cabo as a local swim. Cabo Adventures (10 hours, 4.9 from 1141 reviews, the most reviewed listing on this roster) includes pickup and drop-off, lunch, beverages, wetsuits and equipment. Cabo Trek (9 hours, from $399 per person) includes transport from its Cabo office, a marine-biologist guide and lunch, but excludes hotel pickup. The Ballard Tours day trip (7 hours, from $353 per person) includes the round trip, a sandwich, water and even a towel, one of the few listings that does.

The drive itself is roughly 160 km from Cabo San Lucas, 2 to 2.5 hours, or about 214 km from the San Jose del Cabo airport, 2.5 to 3 hours. Early pickups mean you board the bus before dawn and the boat hours later, so the packing additions are mundane but real: something to eat at 5 a.m., a neck pillow, and layers for an air-conditioned van followed by a hot malecon. The Los Cabos day trip guide covers the full logistics, and the what to expect guide walks through the on-water sequence once you are kitted up.
The last word on packing is honesty about what matters. The items that actually decide whether your day works are the wetsuit or vest you are required to wear, the sunscreen that complies with the rule, the towel almost nobody provides and the cash for a crew that lists gratuities as excluded. Everything else is comfort, and comfort on a 3-hour morning trip is worth about two minutes of packing.
Usually not. Wetsuits are included on most La Paz listings, including the MeXplore, Tuna Tuna Tours, Eco Migrations and Baja Wild Adventures swims. If your listing does not include one, remember that a wetsuit or a life vest is mandatory in the water, so confirm which the operator provides before you go.
Conventional sunscreen is banned in the swim zone; NOM-171 permits biodegradable sunscreen only, applied before entering the water. A rash guard and a hat cover the boat time, and one premium listing includes biodegradable SPF 50 in its price.
No. Selfie sticks, flash and artificial lighting are explicitly prohibited under NOM-171. Standard photos are fine within the distance rules of 2 m from the head and sides and 3 m from the tail, and several operators include GoPro images in the ticket price.
Mostly no. Towels appear in the exclusion lists of at least five major La Paz operators, including MeXplore, Eco Migrations and La Paz Whale Sharks VIP Tours. Pack a quick-dry towel; it is the single most forgotten item on the roster.
A warm dry layer for after the swim. Mean highs run about 25 C in January and 26 C in February, but wet swimmers lose heat quickly on the morning ride back, and at least one operator names a sweatshirt among its recommended personal items.
Enough for gratuities in small peso notes, plus extra on listings that exclude dock or conservation fees, such as the Sunrider Tours swim. This site publishes no tipping percentages because none are verified; treat the amount as your own call and avoid relying on card payments at the dock.
