Swimming With Sea Lions in La Paz, Mexico: What to Know Before You Go
The sea lion colony at Los Islotes is one of La Paz’s great days on the water. Here’s when to go, what the experience is actually like, and how to book it.
There is a moment at Los Islotes when the rocks stop looking like rocks.
One shape lifts its head. Another slides into the water. Then the sea around the boat is full of California sea lions—calling from the colony, cutting through the water, and occasionally coming close enough to remind you that you are visiting their home, not the other way around.
Swimming with sea lions is one of the experiences people come to La Paz specifically to do. It is playful, wild, and completely different from seeing them from a dock or beach. It is also regulated, seasonal, and best experienced with a local operator who understands both the animals and the protected waters around Espíritu Santo.
Here is what to know before you go.
Where do you swim with sea lions near La Paz?
The best-known encounter is at Los Islotes, a pair of rocky islets north of Espíritu Santo. Boats travel there from La Paz as part of guided snorkeling, scuba-diving, or island-day trips.
The journey is part of the experience. You leave the bay, follow the desert coastline, and move into the protected waters of the Espíritu Santo archipelago. Depending on the trip, the day may also include snorkeling at another site, lunch, or time at one of the island’s beaches.
This is a protected marine environment within the Gulf of California, a region recognized by UNESCO for its extraordinary biodiversity and abundance of marine life. That is why access is managed and why the rules around the colony matter.
When can you swim with the sea lions?
At Los Islotes, in-water sea lion encounters generally run from September 1 through May 31.
Swimming and diving at the colony close during June, July, and August, when the sea lions are breeding and raising pups. Boats may still visit the area for observation, but guests should not expect to enter the water with the colony during the seasonal closure.
Wildlife regulations, weather, and access conditions can change. Confirm the current rules with your operator when you book—especially if swimming with the sea lions is the main reason for your trip.
You are visiting their home, not the other way around.
What is the experience actually like?
The sea lions are not performing, and no two visits are identical.
Some days, younger animals are highly curious and move around snorkelers like underwater puppies. On other days, they keep more distance. You may see adults resting on the rocks, pups near the colony, and sea lions moving through schools of fish below you.
What tends to surprise people is their speed. A sea lion can turn, dive, and disappear before you have fully registered that it was beside you. The best approach is to stay calm, move slowly, and let the animals decide how close the encounter becomes.
Your guide will explain where to enter, how to position yourself, and when it is time to return to the boat.
Should you snorkel or scuba dive with them?
Snorkeling is the easiest way to experience Los Islotes. You do not need a scuba certification, and many tours include the mask, snorkel, fins, flotation gear, and wetsuit. You should still be reasonably comfortable in open water and tell the operator honestly about your swimming ability.
Scuba diving offers a different perspective. Certified divers can watch the sea lions move through the water column and explore the marine life around the rocks below the surface. Certification and recent dive experience may be required, and the operator may recommend a refresher if it has been a while.
If you are traveling with a mixed group, look for a trip that can accommodate both snorkelers and certified divers—or choose a snorkeling-focused day everyone can enjoy together.
Is swimming with sea lions safe?
Sea lions are wild animals. The experience is generally approachable when it is run by an experienced, permitted operator and guests follow the guide, but it should never be treated like swimming with a trained animal.
Responsible encounters are simple:
Do not touch, feed, chase, corner, or block a sea lion.
Give adults and animals resting near the colony plenty of space.
Let curious animals approach on their own.
Keep cameras and loose equipment controlled.
Follow the guide’s instructions about distance, entry points, and time in the water.
Never enter a protected wildlife area independently.
If an operator promises that you will hold, pet, or pose with a sea lion, choose another operator.
Can children do the trip?
Often, yes—but the answer depends on the child and the operator.
The boat ride can be long, conditions can change, and the snorkeling happens in open water. Ask about minimum ages, flotation equipment, guide-to-guest ratios, bathroom access, shade, and whether a child who decides not to snorkel can remain safely on the boat with an adult.
For nervous swimmers, a private or small-group trip can make the day feel much more manageable.
What should you bring?
Most operators provide the core snorkeling or diving equipment, but confirm what is included before departure.
A swimsuit and towel
Sun protection and a hat that stays secure on the boat
A light layer or windbreaker for the ride
Water and any personal snacks not included with the trip
Seasickness medication if you are prone to motion sickness
An underwater camera with a wrist strap or lanyard
A dry bag for your phone and valuables
Your scuba certification details if you are booking a dive
The wind and sun can feel stronger on the ride home than they did at the dock. Even on a warm day, the light layer earns its place in the bag.
How much time should you allow?
Treat this as a full day on the water rather than a quick activity between breakfast and lunch.
Departure time, boat speed, weather, and the exact itinerary vary. Many trips combine Los Islotes with other parts of Espíritu Santo, so the experience is often as much an island day as it is a single wildlife stop.
Keep the evening easy. A shower, a sunset walk on the Malecón, and dinner nearby is the right amount of ambition after a day in the Sea of Cortez.
