Experience Highlights

Guided Tours

This tour begins with a hotel pickup and then continues to the boat that takes you to Isabela Island. Your group will have a maximum of 10 participants and will be led by a naturalist guide with extensive knowledge of the Galápagos
Hot lava erupting in the cold Pacific waters created the tunnels. On the way to the dive site, you’ll stop at the Rock Union to do some bird watching. Before you enter the water, you’ll see natural bridges and above ground tunnels also formed by lava— keep an eye out for blue-footed boobies waddling around the volcanic rocks.

Finally, you’ll reach a dive site called El Finado. Snorkelers come here to look for sea turtles, seahorses, and Galápagos penguins. Calm water makes it easy to explore the underwater scenery. Once you’re done exploring, you’ll head back to the boat for a boxed lunch and then return to the port.

Water bottle, comfortable clothes, hat, sunblock, sun glasses, swimsuit, sneakers, a wind breaker, and money for tips.

Traveler Comments

This is a beautiful location. A lot of geological formations, blue-footed boobies, sea turtles, rays, etc. The tour guide was great and also gave us a copy of the GoPro underwater videos he created on our Snorkel dive. The boat captain and his assistant were very helpful when we needed help with the Snorkelling equipment.


We loved EVERYTHING about this tour.

This tour was the BEST! Our guide was amazing, knowledgeable, friendly, and kind. He was funny, helpful, and took photos of us in beautiful locations. We saw every animal we could have hoped for. Our guide knew where to find the animals and made sure we all saw every shark and every boobie. He even shared his photos that he took with us so we could take them home as a souvenir. This was the best tour of our trip and recommend everyone go to the Lava Tunnels with Carlos!
