2 Best Sights in Sintra, the Estoril Coast, and the Setúbal Peninsula, Portugal

A favorite destination for celebrities, Comporta's snow-white sands are dotted with colorful sun loungers and straw-roofed beach huts selling cocktails as well as fresh seafood, and the clear, bright blue invites you to take a cooling dip. Although one of the busier beaches in the Alentejo, this is still quieter than the beaches of the Algarve, and there’s plenty of elbow room even during the summer high season. Amenities: parking (no fee); toilets; food and drink; water sports. Best for: swimming; walking.

Surfers can always be seen braving the waves here regardless of the season. The undertow can be dangerous, and even accomplished swimmers have had to summon lifeguards. If you prefer something more sedate, this beach—with the Serra da Sintra serving as a backdrop—is an ideal spot to watch the sunset. Amenities: food and drink; parking (no fee); showers; toilets. Best for: sunset; surfing; windsurfing.
