Los Tuneles is one of the most interesting and popular places in Isabela Island. The area is known as Cabo Rosa and is the result of portions of lava platforms collapsing into the sea, creating a natural sea barrier full of underwater lava arches and tunnels. Los Tuneles is protected from the sea elements and therefore usually has calm and quiet conditions inside.

The underwater lava tunnels are home to many animal species such as blue footed boobies, penguins, sea lions, white tip sharks, sea horses, sea turtles, giant mantas, eagle, sting and golden rays. It is the perfect place for marine life to enjoy important life processes such as breeding, mating, feeding, resting, nesting and playing.

When you are in the water you can experience these things for yourself. Playing with a baby sea lion or swimming next to a sea turtle is a great way to spend the afternoon.

Sierra Negra Volcano has one of the biggest and most amazing calderas of an active volcano on earth. It is also the only active volcano that you can visit in the Galapagos Islands.

Our tour takes you on a 16km hike along the edge of the caldera (volcanic crater). Great views of the landscape and excellent photos can be taken during the hike.

As part of the tour, depending on the group and conditions, it is also possible to visit the area of Volcan Chico. We can either go over the edge and 300 metres down outside the main caldera, or we keep walking along the edge and visit the last eruption site of Sierra Negra Volcano in 2005 on the newest trail opened by the Galapagos National Park.

So why should you visit Sierra Negra Volcano? The first reason is the spectacular views of this massive caldera and Isabela Island itself. On a clear day you have the chance to see the Sierra Negra Volcano’s caldera, the whole chain of six volcanoes that form Isabela Island, and also Elizabeth Bay and Fernandina Island all in the same picture!

The second and maybe the most important reason you should visit Sierra Negra Volcano is to understand and witness the continuing geological process of the Galapagos Islands.

From the main dock we take a 45 minute boat ride around the Tintoreras lava formations where we will see colonies of penguins. Then we stop at one of the lava platforms and walk across the flat terrain for 1 hour where we can see many marine iguanas and the important Galapagos sea lions colonies. After that we will enter the water and snorkel where we can see Galapagos sharks, sea turtles, sea lions and swimming marine iguanas.

As you travel towards the Wall of Tears you will pass a beautiful beach where you can stop and swim. From there you will enter the Wetlands where there are short trails you can take to explore the area and see various laval formations. On your ride you will likely see giant tortoises and many Galapagos sea birds.

Once you pass through the Wetlands you will arrive at the Wall of Tears which is an important part of the history of Isabela Island. Option for Biking Tour.
