Ilha do Mar Casado

Ilha do Mar Casado is a coastal island with beach formation in Guarujá, consisting of a hill connected to a roughly 400-meter-long beach with calm waters. This formation creates a natural barrier between two distinct coastal areas.

Until the mid-1990s, this location drew surfers and beachgoers, then experienced significant changes. The construction of the Hôtel Jequitimar complex in 2005 shaped its later development.

This location serves as a natural meeting point where locals and visitors gather for water sports like stand-up paddling and snorkeling. The cove is regularly used by people seeking a relaxed day by the water.

During low tide, visitors can walk directly to the island, while high tide creates separation that requires swimming or boat transportation. Tidal conditions change throughout the day, so checking the tides before your visit helps with planning.

This location exhibits a rare tombolo formation, where sand deposits naturally connect the island to the mainland during specific tidal conditions. This geological feature makes the shifting nature of the landscape a remarkable natural display.
