Morro do Mar Casado, or more precisely «Mar Casado Island», is a rocky, forested hill in Guarujá between Pernambuco and Sorocotuba beaches. Its name means «married sea», after a striking natural event: at high tide the waters of the Mar Casado and Pernambuco beaches meet and become one, and the hill turns into an island; then, as the tide falls, the waters part again and the sandbar reappears. Geographers call this formation a «tombolo», a spit or strip of sand and shingle joining the mainland to a nearby island, built up by waves bending around the island and meeting behind it. The spot was popular with surfers, and a large hotel was built beside it in 2005. The best time to visit is at low tide, when you can walk the sandbar between the two seas and watch them meet, keeping an eye on when the tide turns. Combine it with neighbouring Pernambuco beach, and check the tide table before you go.

Between Pernambuco and Sorocotuba beaches, Guarujá
Because the two beaches' waters meet at high tide, turning the hill into an island, then part again at low tide.
