01Praia Fluvial de Santa Clara
Odemira’s lake beach
The municipality of Odemira is best known for its Atlantic beaches, from Vila Nova de Milfontes down to Zambujeira do Mar. Inland, among wooded hills near the village of Santa Clara-a-Velha, it also has a river beach: the Praia Fluvial da Albufeira de Santa Clara, on the reservoir behind the Santa Clara dam. The municipal tourism office calls it an essential stop on the beach tour of the municipality.
The reservoir is enormous. The council gives its surface as 1,986 hectares and says it is considered one of the largest in Europe. It was built under the Estado Novo regime, is fed by the river Mira, and its water travels on through 84.9 kilometres of canals to farms nearer the coast. From the top of the dam wall, the tourism office says, the size of it all is impressive.

Why children like it
The water is calm. There’s no surf and no undertow of the kind you get on the Atlantic coast, which makes a reservoir beach an easier place for toddlers and for children who are nervous in waves. The tourism office describes a bathing area with a floating platform and a leisure area. Older children who can swim well enjoy having somewhere to swim out to under the lifeguards’ eye.
There is also room to do things on the water. The municipality lists canoeing, and says you can take boat trips on the lake or fish for largemouth bass, which are plentiful here. It also mentions windsurfing and kitesurfing among the facilities, so on a breezy day you may have sails to watch.

Lifeguards and the 2026 season
Santa Clara had a Blue Flag in 2026 and holds the Quercus Qualidade de Ouro award for excellent water quality. Its 2026 bathing season ran from 30 May to 30 September, the longest of any river beach in the Alentejo that year according to the regional press, which listed most inland beaches as closing on 13 September. The council says its beaches are watched every day of the season from 10:00 to 19:00.
Fresh water still needs care, and a reservoir can be deep a short way from the edge. Keep small children in the shallows close to you, and check the lifeguard flag.

Facilities
The municipal listing gives parking, toilets, a lifeguard and canoeing at the beach. It doesn’t list a café or restaurant at the beach itself, so bring a picnic, drinks and shade. The village of Santa Clara-a-Velha has a picnic park beside the Fonte do Azinhal, a fountain dated 1892 and restored in 1995, according to the tourism office.
05Praia Fluvial de Santa Clara
Honest downsides
It’s inland, so from the coast it is a separate trip rather than a quick hop. Facilities are simpler than on the coastal beaches. And a reservoir changes: the 2026 rules noted by the regional press say inland bathing waters can have temporary restrictions linked to changing water levels, so in a dry year the beach can look different from the photos. Check with the Odemira tourism office before a special trip, especially late in the season.

Making a day of it
Combine the lake with a walk around Santa Clara-a-Velha. The tourism office recommends the white village and its church of Santa Clara de Assis, and on the road to the dam there’s an old bridge, the Ponte de D. Maria, which locals also call the Roman bridge.
Back on the coast, Praia do Carvalhal and Praia da Zambujeira do Mar are the nearest sea beaches, and Praia das Furnas at Vila Nova de Milfontes is where the Mira finally reaches the sea. Older children might also like the Odemira skate park in the municipality’s main town.
