In shortWhale shark season at La Paz runs from October through May, which is a separate animal, a separate bay and a separate booking from the winter whale season at Cabo San Lucas. Boats are capped at 36 feet and snorkellers go in groups of five. From Los Cabos it is a 10-hour day with hotel pickup, gear and lunch.

Whale shark season in La Paz runs October through May
The whale shark has nothing to do with the whale season at Cabo San Lucas beyond the word in its name. It is a shark that feeds by filtering, you get in the water with it, and the activity belongs to La Paz, up the coast north of Los Cabos. Its season runs from October through May.
Those dates sit around the whale window rather than inside it. Whale watching at the cape is authorized for 2026-2027 from 15 December 2026 to 30 April 2027, with the peak falling between January and March, so from mid-December to the end of April both activities are live at the same time. October and November dates give you the sharks without a legal whale season, and May dates give you the sharks after the whale notice has expired.
One thing to keep in mind when you plan a trip around it: the whale shark activity has been suspended part way through a season before. Treat your date as something to confirm rather than as a fixture, and do not build an entire holiday around a single morning in the water.
How the day works from a Los Cabos hotel
Budget the whole day. The tour on this site runs 10 hours with hotel pickup and drop-off included, and a good share of that time is road rather than water, because the bay where the sharks feed is well north of the cape. You leave early, you snorkel in the middle of the day, and you are back in the late afternoon or early evening.
Water time is shorter than first-timers expect, and that is a function of the group limit rather than the operator. With five snorkellers in the water at a time, a boatload goes in by rotation, so you get several short turns instead of one long swim. Use each turn properly: have your mask sorted and your fins on while the boat is still moving between sightings, so you can slide in the second the guide calls you.
Wetsuits and snorkelling equipment are included, along with a professional guide, beverages and freshly prepared classic Baja-style fish tacos. Gratuities and towels are not included, so pack a towel and something dry to wear for the drive home.
- Bring a towel and a dry change of clothes; towels are not provided
- Wetsuit and snorkel gear come with the tour, so you are not renting anything on the dock
- Lunch is fish tacos, prepared fresh, and drinks are included
- A professional guide is included; the listing does not specify a guide in English
- Hotel pickup and drop-off in the Los Cabos area is part of the booking

Whale shark rules in La Paz: boat size and group limits
Two caps set how the day runs. Boats working with whale sharks at La Paz are capped at 36 feet, and the in-water groups are capped at five. That is why the day feels nothing like a 2 or 2.5 hour whale departure from the marina, where the regulation holds everyone at a distance and nobody gets wet.
The contrast with whale watching is worth having clear before you book either one, because the two are routinely confused.

The water, the visibility and how to behave next to a filter feeder
Expect cool water and poor clarity, and plan for both. The wetsuit in the inclusions list is there because the Gulf side is not warm in winter, and the sharks are in that bay to feed, so the water carries the food they are filtering. You are not snorkelling over a clear reef. Visibility is often short enough that the animal appears out of green water a few body lengths away and is gone again quickly.
Behaviour rules come from the guide, and they are not optional if you want the groups after yours to get a turn. Slide in quietly rather than jumping, swim beside the shark and slightly back from the head, and stay out of its path so it never has to change direction because of you. Hands stay off the animal. No diving down on top of it, no kicking hard enough to churn the surface right in front of it, and no crowding once a second group is waiting on the boat.
A filter feeder at the surface moves slowly and then is suddenly faster than you are. The sensible approach is to let it come to you, hold your line and let it pass, then surface and wait for the guide to reposition the boat instead of chasing.
- Enter the water when the guide says so, five at a time, and leave when called back
- Keep clear of the head and the tail; swim parallel, off to one side
- Keep your hands off the shark and do not dive down onto it
- Keep your fin kicks small and under the surface
- Be confident swimming in open bay water, where there is no bottom to stand on
Adding a shark day to a whale-watching trip
Put them on separate days. A whale trip from the marina is 2 to 2.5 hours and you can be back for lunch; the La Paz day is 10 hours with an early pickup, and stacking the two means arriving at one of them tired and salty. If your dates fall between mid-December and the end of April, both are available, so there is no reason to compress them.
The order that works best is the whale trip first, in the morning, while you are fresh and before you know how your stomach handles a boat, then the shark day later in the stay. January and February are the strongest weeks for whales, with mean wind at 10 metres sitting near 3.9 m/s, and they fall inside the October to May shark window as well.
For the shark day, choose the version that includes road transport and a meal rather than assembling it yourself. The tour below covers hotel pickup and drop-off, wetsuits and snorkel gear, a guide, drinks and fish tacos, which removes every moving part from a day that is mostly spent getting there and back.
Questions people ask
Can I see whale sharks on a boat trip from Cabo San Lucas marina?
No. The whale shark activity belongs to La Paz, north up the coast, and reaching it from the cape is a 10-hour day. Departures from Cabo San Lucas marina run 2 to 2.5 hours inside the Cabo San Lucas Flora and Fauna Protection Area and are whale-watching trips, where swimming and diving are prohibited during observation.
Can I do whale watching and whale sharks on the same day?
It is not worth attempting. The shark trip takes 10 hours with hotel pickup at the start of it, and the cape whale departures are 2 to 2.5 hours. Put the whale boat on a morning when you are free and the La Paz day on its own date, which also gives you a spare slot if one of the two cannot run.
Do I need to be a good swimmer to snorkel with whale sharks?
You should be comfortable swimming in open water without touching the bottom. A wetsuit and snorkelling equipment are included and the suit helps you float, but you still enter from a boat in a bay and swim under your own power in groups of five. If anyone in your party is uneasy in the sea, the 2 to 2.5 hour whale trips from the marina are the better use of their day.
Is there any legal way to swim with whales instead?
Not with whales at Cabo, where swimming and diving during whale observation are prohibited outright. The one in-water cetacean exception in Baja California Sur is orcas at La Ventana, which the state legalized under a pilot scheme capped at 24 boats a day and at least a six-hour commitment from Los Cabos. Confirm that the pilot authorization is running for your own dates before you plan around it.
Why is the boat so small?
Boats working with whale sharks at La Paz are capped at 36 feet, and the in-water groups are capped at five people. That is a deliberately tight set of limits, and it is why your time beside the animal comes in short rotations rather than one continuous swim.
