Tunnels: This is one of the most spectacular snorkeling sites in Isabela, the water is shallow, calm and very clear, a marine sanctuary. A series of lava flows have produced unique geological formations, a series of arches and tunnels, below and above the water, where a large number of endemic Galapagos species live. The entrance to the site is not deep and the waves can be very strong, for this reason, access to this place is not always very feasible. The best time to visit Los Túneles is between January and May.

Twin Craters: The Twin Craters are, in fact, not craters. These impressive holes were formed by magma (lava) domes which hardened on the outside but continued to flow on the inside, leaving huge but empty chambers that collapsed with the passing of time, creating this breathtaking scenery that resembles two pit crates. The Twins are located in the highlands of Santa Cruz Island and are surrounded by lush and green forests, dominated by the endemic Scalesia plants. It is possible to walk along the rim of the craters to better appreciate the magnitude of the holes as well as the local flora and fauna. This site is also one of the most likely places to observe the endemic short-ear owl of the Galapagos.
