3 Best Sights in Lagos, The Algarve

This beautiful beach has calm, turquoise waters that are perfect for snorkeling, and cave-studded cliffs that can be visited on boat tours. You can reach Praia de Dona Ana by car or on an enjoyable 30-minute walk along a cliff top. This small beach can get packed, especially when the tide comes in and the sand disappears. Parking is difficult and the steep steps down to the sand can be trying, but it's worth the effort to visit what has been voted one of the most beautiful beaches in the world. Amenities: food and drink; lifeguards. Best for: snorkeling.

Curving like a crescent moon the entire distance between Lagos and Alvor, Meia Praia is the largest beach in the area and one of the best centers for water sports. The golden sand extends for 4 km (2½ miles), and the water is calm and clear. You can walk to it from Lagos city center in less than five minutes by crossing the footbridge, but there's also a bus from the riverfront Avenida dos Descobrimentos and a summer-only ferry service a few hundred yards from Forte Ponta da Bandeira. A section is reserved for nudists. Amenities: food and drink; lifeguards; parking (no fee); showers. Best for: nudists; solitude; swimming; walking; windsurfing.

They say the best things come in small packages, and that's certainly the case here. A short way beyond Praia de Dona Ana, little Praia do Camilo is a hugely popular cove. Just beyond it is the Ponta da Piedade, a much-photographed group of rock arches and grottoes. Praia do Camilo is accessed via a long, wooden walkway through picturesque cliffs. At the top of the cliff restaurant O Camilo offers stunning views over the beach, and serves great oysters. Amenities: parking (free). Best for: snorkeling.
