Get up close and personal to a colony of sea lions by getting in the water with them. If you're bold (and willing to brave the cold Atlantic waters), then book this snorkel excursion in the Reserva Natural de Punta Loma, a colony of 600 sea lions. The majority of this colony lives here year round without predators. You'll see them completely wild. They are not manipulated or fed to encourage interaction.

There are also diving training and excursions if you prefer to scuba dive.
