Isabela Island

When we arrived on Isabela Island, the first thing that screamed to be noticed was Sierra Negra volcano dominating the horizon. Once we had settled into the accommodation, we went for a hike to see the caldera of Sierra Negra, which has a diameter of around 12km and was stunning. The first day finished with some beers and sunset.

The second day was spent exploring the Isabela Island lava tunnels, an amazing underwater complex like no other. They were formed when Sierra Negra erupted, and it's lava hardened faster on the outside whilst it flowed. This caused a complex tunnel network that over time caved in, causing a natural canal system teeming with wildlife. While snorkelling, we saw seaturtles, penguins, blue-footed boobies and sea lions.Leggi altro
