Fodor's Expert Review Praia da Foz do Arelho

Across the mouth of the Óbidos Lagoon, a large spit of sand juts out into the brackish tidal water. The broad expanse of sand here and the calm waters of the lagoon make it popular with families with young kids, not least because the beaches here have been awarded the coveted Blue Flag (for water quality, safety, and access) several years running. As well as the public facilities, there are several lively esplanades along the promenade. Amenites: food and drink; lifeguards; parking (no fee); showers; toilets. Best for: partiers; sunset; swimming; windsurfing.
