Swim with giant sea turtles, rays, sharks and sea horses.
I think Cabo Rosa Tunnels is the best snorkel you will have in the Galapagos Islands. Start by heading to a rock called the Union a small islet located in the open sea where you can see Pelicans, nazca boobies and blue footed boobies and the occasional sea lion resting on the rocks.
After this short stop you will navigate for approximately 45 minutes to reach one of the most beautiful rock lava formations landscapes of the Galapagos Islands, it is called tunnels since in ancient eruptions, the lava passed under the formed land tunnels that then collapsed and gave rise to these arches over the water where you can clearly see vegetation that comes out of the rocks, the crystal clear water, the sea lions flutter between the arches.
NOTE: The tour may suffer variations due to the waves you receive that day, the first thing will be for us, the safety of the passengers.
