Visit Las Tintoreras to see the colony of white tip sharks which can often be seen resting in a lava canal. Snorkel in the shallows or relax on the beach with a sea lion colony.
In the afternoon, see the Tortoise Breeding Center and learn about tortoise conservation. Giant tortoise eggs are collected and brought to the center to be hatched. After five years, they are released back into the wild. Hike Humedales, a trail complex to Orchilla Hill, from this viewpoint you can admire the bay of Puerto Villamil and Volcano Sierra Negra. Continue on to the Wall of Tears, a big wall built by prisoners housed on the islands many years ago.

This was my first experience with Adventure Life - and I couldn't have been more pleased with the trip. The guides and local staff in both Buenos Aires and Uruguay were terrific - extremely helpful and accommodating. I really enjoyed meeting the friendly staff in Buenos Aires in person (I left my bags with them for the afternoon).
