Praia dos Três Irmãos
The stunning cove-like Praia dos Três Irmãos has lots of little rocks in the water, which means it can either be great for snorkeling or bad for unwitting toes, depending on the tide. Beyond the little ones under feet, this beach has a range of interesting rock formations to check out, too. If the beach gets too crowded, there's always space to spare on one of the beaches either side. Amenities: food and drink; lifeguards; parking (no fee); toilets. Best for: snorkeling; walking.
