Galapagos Snorkeling and Scuba Diving Guide

Galapagos Snorkeling and Scuba Diving Guide

After snorkeling and Scuba diving in Costa Rica, Belize, Isreal’s red sea, Florida, and Mexico, I can confidently say that snorkeling in the Galapagos is one of the best destinations in the world for the sport. With the extreme pressure to protect the waters and park, the huge conservation efforts in preservation, and millions of years in isolation, this destination is as pristine as it gets.

The stunning marine biodiversity of the Galapagos islands attracts thousands of visitors every year. Off the coast of this beautiful archipelago, you can stick on a mask and fins and you’ll soon be swimming amongst coral reefs with the likes of Galapagos sea lions, Iguanas, hammerhead sharks, and much more. Read below to see our tips for maximizing your Galapagos snorkeling and Scuba diving experience.Galapagos Reef

When to Go – Galapagos Snorkeling &/Scuba Diving

When to go snorkeling is a decision that comes down to two primary factors. The first, what water temperature are you comfortable swimming in? Secondly, which Galapagos marine animals do you want to see?

Galapagos Water Temperature 

The water temperature of the Galapagos can fluctuate significantly during the year. As this region straddles the equator, you only encounter two seasons: Rainy (hot) and Dry (cooler).  Below are the season descriptions in full detail.

Warm Season January – June  Snorkeling in the Galapagos

This season is the warmest and sunniest period of the year, with occasional sessions of drizzling. With air temperatures commonly between 75-85 degrees during the day, the water temperature is common in the high 70s F (25+°C ) and can even reach 80 degrees (26 °C). This is a pleasant and refreshing temperature for swimming, and you generally won’t need a wetsuit.

Galapagos Wildlife & Highlights Throughout the Warm Season

My first Galapagos snorkeling experience was during this season on the Legend Galapagos Cruise. The best part was that every snorkeling tour I went on was in swimming trunks, snorkel and mask, and fins. No shirt and the water felt spectacular. I floated along with a huge crowd of Galapagos turtles, watched countless sea lions acrobatically darting through the water, witnessed marine iguanas torpedo down and chomp on algae. There were many vividly colored blue and red starfish, and huge schools of fish. Snorkeling during this season was spectacular, and I had no complaints! If you are a scuba diver, however, read on to see the benefits of the next season.

Season Highlights

  • Adult male marine iguanas on Española Island become brightly colored to attract mates (January)
  • Land Iguana mate on Isabela Island (January)
  • Galápagos sea lions breeding (May through January)
  • Whale sharks may be seen in the far northwestern islands towards late June
  • Galápagos green turtles arrive to lay eggs on beaches

July through December – Cooler Season

During the “garúa season”, air temperatures average out at 76.4 F (24.4) degrees. The water temperature drops down to the low 70s surrounding most of the islands, and can down to nearly 60 degrees on the west side of Isabela.

On my second trip, I snorkeling in August on the Elite Galapagos Cruise, the time with the coldest air temperatures (70 F, 21 C), and it was a dramatic change. I had on a wet suit on every excursion except one occasion, and that instance took my breath away for a few moments! While many of the guests could snorkel a solid 45 minutes to an hour on my first Galapagos stint during the warm season, some guests were getting out of the water after 20 – 30 minutes on the second Galapagos Snorkel adventure. That being said, there were some benefits for snorkeling, which exponentially increases for scuba divers.


A little chilly down there?

Galapagos Wildlife & Highlights throughout the Dry Season

If you care less about the cold and more about wildlife, then this is the time to come to maximize spotting marine wildlife. The Humbolt current, which flows from the Southern tip of South America, brings more than just cold temperatures to this tropical climate. Upwellings occur, a phenomenon in which winds push away warm nutrient-depleted waters and replace them with nutrient-rich waters from deep below the surface. This nutrient-rich water rapidly multiplies the number of smaller organisms, resulting in an explosive food chain reaction.

Season Highlights

  • Increased Whale and dolphin sightings
  • Whale sharks in wolf and Darwin Islands
  •  Galápagos sea lions give birth to pups
  • Galápagos penguins courting on Bartolomé Island
  • Highly active sea lions (September)
  •  Galapagos fur seal mating season begins (October)
  • Significant Galápagos Green turtle activity with peak mating season (November to January)

Wetsuit thickness Galapagos Snorkeling and Scuba Diving

For snorkelers, wetsuits of 3mm thickness for snorkeling in the Galapagos is sufficient, as you won’t be diving deeply. If you are Scuba diving, 5mm thickness is recommended, with gloves and hood. And for those that get extra cold, bring the 7mm. Those going on liveaboard diving trips, consult with our trip advisors, as the cruise may have all the materials you need!

Top Snorkeling Sights in the Galapagos

1. Kicker Rock

Kicker Rock is an immense lava cone jutting out of the Galapagos sea. This impressive geological site towers 500 feet tall (140 m).

When I snorkeling this site, we brought life jackets as the water is a little deeper. We snorkeled through the canyons that run through the middle, and it was full of wildlife.

While snorkeling, I saw Galapagos sea lions, 10+ sea turtles lazily floating by, two large sharks seemingly minding their own business and a massive schools of fish.

My guide swam underneath one school, and then up through the middle.

The thousands of fishing parted, surrounding him. It appeared as if he were in the middle of a tornado!  I think of all of the Galapagos snorkeling sites, this was my favorite. We weren’t lucky enough to see the hammerhead sharks, but from time to time big schools of them drift past this area.

2. Devil’s Crown

The devil’s crown a site off of Floreana known for its stronger currents and incredible diversity of marine life. Instead of trying to fight the currents while snorkeling, simply relax and let the tide take you for a ride. You will see sea starfish, King Angelfish, Rainbow Wrasse, Pufferfish. If you get lucky, you may see hammerhead sharks!

3. Bachas Beach

Las Bachas beach is found on the northern coast of Santa Cruz Island. This site cannot be reached by road and requires a guide either through a tour or a multi-day cruise. This is a water entrance, leading to many beautiful creatures including butterflyfish, parrotfish, and dusky wrasses, eels, and silvertip shark. Galápagos green turtles constantly swim through this area and feed on algae-covered rocks, as Las Bachas is an important egg-laying site.

4. Pinnacle Rock and Bartolome

One of the greatest snorkeling sites of the world is located on the northeastern coast of Santiago island.

I swam with numerous shark species, sea turtles, Galapagos penguins, Galapagos sea lions, and hundreds of colored fish.

Bartolome is one of the most spectacular snorkeling sites of the entire Galapagos archipelago.

Bartolome is also accessible on a one-day boat trip from Porto Ayora, or on a multi-day cruise. Majestic schools of razor surgeonfish graze algae from rock to rock. Find hundreds of red starfish, beautifully colored parrotfish, king angelfish, Mexican hogfish, and the rarer squirrelfish.

5. Gardner Bay

This site is an islet nearby to Española, the southernmost island of Galápagos. This is the spot to swim with playful sea lions, that frolic throughout the waters. These strange creatures display impressive acrobatic movements. They often get up close personal, seemingly asking you to join in on their funny dances. You will also find marine iguana swimming in the water at this site, but the popular attraction is the sea lions!


He is coming to play with you!

6. Tagus Cove

Located off Isabela island, whalers and pirates made their mark on the cliffs with the names on their ships. Snorkeling here is world-class, with green turtles, stingrays, yellow seahorses for the luckiest ones! You will find rocky cliffs home to sponges, algae, gorgonians, and orange cup corals (rough corals with magnificent polyps of yellow, orange, or pink.)  You may also be fortunate enough to swim with the Galápagos penguin and flightless cormorant!


7. Los Tuneles

Located off the southern coast of Isabela Island. This name of this site translates to the tunnels, derived from the of pools, tunnels, and passages formed by lava flows. This area is comprised of a calm lagoon, where you will snorkel a site full of stingrays, rainbow wrasse, golden rays, seahorses, abundant sea turtles, and even sharks!

Galapagos Snorkeling Tips

  • To expel water from your snorkel, make a high hat sound “T” sound as hard as you can. Depending on the season, water may get in your snorkel from time to time
  • Put on plenty of sunscreen in the Galapagos, as the sun is powerful in Ecuador and you will burn within 15-20 minutes!
  • Get snorkeling Fins That Fit. While snorkeling or scuba diving in Galapagos, you want fins that are neither too tight, nor too loose. If you have any pain or discomfort, its time to try on a new pair. Read more about the different types of fins here
  • Swim Slowly! Exhaustion is a common problem for first-time snorkelers in the Galapagos. Swimming can sap your energy quickly if you overexert yourself. The best method for snorkeling is to stay relaxed and calm. The snorkel slightly limits your breath, so keep your activity level lower so you don’t find yourself breathing too hard.

A Note On Cold Temperature – Galapagos Snorkeling

If you are somebody that is very sensitive to the cold, it might be better to visit the Islands when the waters are a bit warmer. The marine life will be incredible regardless of the time you visit. The question those sensitive to the cold have ask themselves is this: Is missing one or two species of Galapagos wildlife worth the 30 minutes you might miss out because you were too cold to go on?


Ask about the wetsuits before the tour!
