If you're looking for dramatic volcanic landscapes, incredible wildlife encounters, and unforgettable snorkeling experiences, Isabela Island should be at the top of your Galapagos itinerary.
As the largest island in the archipelago, Isabela offers a unique combination of adventure, nature, and breathing disease that cannot be found anywhere else in the world.
Why Visit Isabela Island?
Unlike the busier islands of Santa Cruz and San Cristobal, Isabela offers a more relaxed atmosphere while still providing access to some of the most spectacular natural attractions in the Galapagos. The island is home to active volcanoes, marine iguanas, penguins, flamingos, sea turtles, and counter endemic species.
Visitors can choose from a wide range of tours depending on their interests.
The Tunnels: The Best Snorkeling Tour in Isabela
The Tunnels is widely considered one of the top snorkeling destinations in the Galapagos.
Over thousands of years, lava flows created a network of natural archs and tunnels above crystal-clear waters. During the tour, visitors can observe:
- Be turtles
- Seahorses
- Reef sharks
- Penguins
- Rays
- Blue-footed boobies
The excursion combines boat navigation, multiple snorkeling sessions, and a short walk through stunning volcanic formations.

For travellers who enjoy hiking, Sierra Negra Volcano is a most-see destination.
The volcano features one of the world's largest active volcanic boilers and offers spectacular panoramic views. The excursion includes transportation to the park entrance and a guided hike through lava fields and volcanic landscape.
The trail provides a completely different perspective of the Galapagos compared to the marine- focused excursions.
