Just 15 km from Puerto Madryn, the Punta Loma Natural Reserve hosts a stable colony of around 600 South American sea lions (Otaria flavescens). Diving here is different from the urban bay experience: you take a 25-minute boat ride and descend among volcanic rock, short caves and kelp, with sea lions as the undisputed protagonists. The animals approach out of curiosity, nibble at fins and wetsuits, and circle divers in completely unexpected ways.
The seabed combines rock, mussels, sea urchins, starfish and a range of Patagonian coastal fish. Visibility averages 8-12 metres depending on the season; depth reaches 18 m in some channels. A valid dive certification (PADI or equivalent) is required for scuba; snorkelling with sea lions is available without certification. Water temperature ranges from 10°C in winter to 18°C in summer.
The recommended season runs November to April, when the water is slightly warmer and sea lions are most active. Trips depart early from Puerto Madryn’s port. Active operators: Aquatours Buceo (+54 9 280 4582559), Lobo Larsen Buceo (Av. Roca 885) and Abramar Buceo.
