Animal habitat
Cabo Polonio National Park, located on the Atlantic coast in the Rocha Department, is renowned for its vast mobile sand dunes, rocky headlands, and large colonies of sea lions. Access to the park is strictly restricted to protect its fragile ecosystem; visitors must use special 4x4 vehicles to travel the 7 kilometers from the main road to the village. The village itself is a rustic settlement with no connection to the national power grid, preserving its unique, off-the-grid character. The Cabo Polonio lighthouse, inaugurated in 1881, is an iconic landmark offering panoramic views of the coastline and the nearby islands, which serve as important breeding grounds for South American sea lions (Otaria flavescens) and fur seals (Arctocephalus australis). The park was incorporated into the National System of Protected Areas (SNAP) in 2009, highlighting its significance for conservation and sustainable tourism.

Best season
The best time to observe the sea lion colony is December to March, when animals come ashore. Outside these months, colonies are often smaller or animals are at sea.
Best time of day
Morning and evening hours are good when sea lions rest on the beach or enter the water. In the midday heat, many animals retreat to cooler water.
Etiquette
Maintain a minimum distance of at least 50 metres from sea lions to avoid disturbing them. Do not feed the animals and avoid sudden movements or loud noises.
What to bring
Binoculars and a camera with telephoto lens are essential for viewing the colony from a safe distance. Windbreaker and sun protection are recommended due to coastal conditions.
Getting there
The park is reachable only on foot or by 4x4 vehicle across sand dunes. From Cabo Polonio town, a short walk leads to the beach.
What to expect
Sea lions often display relaxed behaviour, best observed in calm wind conditions. Stay still and avoid jerky movements to avoid scaring the animals.
