01Praia Fluvial de Odeleite
The Algarve’s newest river beach
The Praia Fluvial de Odeleite opened in summer 2026 on the reservoir of the Barragem de Odeleite, a dam in the hills of Castro Marim in the eastern Algarve. Expresso reported that years of drought had delayed the opening, and that the winter rains finally filled the reservoir to almost 100%. The official opening was set for Friday 26 June 2026, and Castro Marim council raised the Blue Flag there on Wednesday 1 July.
It was the only inland bathing area in the Algarve with a Blue Flag in 2026. In September 2026 the Guia das Praias Fluviais, a national guide to river beaches, gave it its “Praia Revelação da Região Sul” award (newcomer of the year for the south), according to the council.

Floating pools: how swimming works here
You don’t wade in from a sandy shore. Instead, a floating platform on the reservoir holds two pools, one for children and one for adults. Expresso and SIC give its size as 20 metres long and 10 metres wide. The council explains that the enclosed pools give extra safety, and you reach them by two floating walkways and a bridge.
Above the platform, a sun terrace steps down the bank in tiers, and this is where the bar and changing rooms are. The council’s page also lists shaded areas, places to sit, and picnic spots, with boardwalks and marked paths to protect the banks.
For a family with a toddler, the separate children’s pool is the big attraction. Nobody is trying to keep a small child out of waves, and the edge of the pool is always within reach.

When it is open
This is a summer-only beach with a short season. The government set the 2026 bathing season at Odeleite as 1 July to 31 August, and APA’s data shows the same dates. Press reports gave other end dates (Expresso said 30 September, SIC said 30 August), so for future years check the council’s page before you go.
Lifeguards were hired for the season, according to the council. Outside the bathing season there is no lifeguard. The reservoir is a drinking-water supply, and the council says the project was built partly to stop people bathing in unsafe, unauthorised spots on it, so swim only at the official beach.

Water quality
The council describes the water as good quality and mild in temperature, as you would expect in a reservoir. APA’s most recent 2026 test at Odeleite, in August, found it suitable for bathing.

More to do around the reservoir
The beach is part of a Centro de Atividades Náuticas (water-sports centre) for non-motorised activities. SIC and Expresso mention stand-up paddleboarding. Expresso names local operators offering boat trips, SUP and even gyrocopter flights; book those directly.
There is a story that children will like. The Ribeira de Odeleite, which feeds the reservoir, is nicknamed the “Rio do Dragão Azul” (River of the Blue Dragon) after an aerial photo of it winding through the hills was published, and the Guia das Praias Fluviais describes the reservoir itself as dragon-shaped. Expresso suggests stopping at the viewpoint at the entrance to Odeleite village to see it from above.
The dam behind it was built between 1992 and 1998 to supply public water, and it is connected by a tunnel to the neighbouring Beliche dam. The council calls it the main water store of the eastern Algarve, which is a good hook for a conversation about where drinking water comes from.

Getting there
The beach is near Odeleite village, off the IC27 road that links Castro Marim and Alcoutim. There is a car park, which the council says was planned as part of the project to keep parking organised.

Downsides
- A very short season: in 2026 the lifeguarded season was only July and August.
- It is new, so opening dates and details may change from year to year.
- Inland summers are hot. Bring hats and plenty of water.
- APA’s 2026 data lists no showers or first aid post.

Making a day of it
Odeleite village is worth a wander. Expresso recommends the Casa de Odeleite, a former trading post turned cultural space with a café and a shop selling local products, and the PR4 walking trail along the stream. The Grande Rota do Guadiana (GR15) also passes through. Further north, Praia Fluvial do Pego Fundo at Alcoutim is a river beach with a longer season. Down on the coast at Vila Real de Santo António, the Guadiana fishing school and the town skate park suit older kids.
