Full-day excursion on Isabela Island combining adventure, volcanic exploration, and snorkeling—ideal for travelers seeking a unique experience that blends geology, dramatic landscapes, and marine life.

The tour begins in Puerto Villamil with a transfer to Trillizos Volcano, where the adventure starts with a descent of approximately 130 meters (426 ft) underground using rappel equipment and the assistance of a specialized guide.

During this experience, visitors descend into the volcanic formation to explore this impressive natural system, observing volcanic craters, geological formations, quartz deposits, and lichens formed after past eruptions. This activity provides a close-up understanding of the volcanic dynamics that shaped Isabela Island.

After the exploration, there is time to rest and enjoy lunch before continuing to Concha de Perla, a calm, crystal-clear bay surrounded by mangroves, ideal for swimming and snorkeling.

At this site, guests may observe sea lions, sea turtles, tropical fish, and—during the cooler season—the iconic Galápagos penguins.

The experience includes time for snorkeling and enjoying the marine ecosystem before returning to Puerto Villamil.

At the end of the tour, guests complete a day that combines adventure, nature, and direct contact with the island’s biodiversity.
