This guide brings together only what we could check on 10 November 2026, first on the portal of ODIANA (the Lower Guadiana association) and then in the regional press, always with the date. We found no Alcoutim council pages on these topics in search results; anything we could not find in a reliable source is marked not confirmed.

It lies about 500 m from the village centre, on the Ribeira de Cadavais by the Guadiana (Postal do Algarve, 15 August 2024).
It has held the Accessible Beach (Praia Acessível - Praia para Todos) award since 2005, with free parking, ramp and boardwalk, adapted toilets, bathing assistance, a first-aid post and lifeguards (Postal do Algarve, 23 August 2018).
It held a Blue Flag until 2018, when the municipality switched its focus to the Accessible Beach certification (Postal do Algarve, 9 July 2026).
In 2020 swimming was banned for about two weeks due to microbiological contamination; it reopened after new tests by the Portuguese Environment Agency (APA) (Postal do Algarve, 9 July 2020).

Boat between Alcoutim and Sanlúcar de Guadiana

What we could check:

ODIANA says the boat is included in the zip line ticket price.
The press contradicts itself: in 2019 Postal do Algarve wrote that the return ferry was included if your car was in Spain and cost 1.5 EUR if it was in Portugal; on 22 September 2026 it wrote that the ferry runs roughly every half hour and is not included.
2026-2027 boat timetable, fare and operator: not confirmed in an official source. Check at the pier before crossing.

Where to stay

A few practical criteria:

Staying in the village lets you walk to the castle, the pier and the river beach.
Ask your accommodation about the current boat service and the zip line season.
Before booking, look at the total price with taxes and cleaning and check the local accommodation (AL) registration number.

If you run a property in Alcoutim or the Lower Guadiana

What travellers typically ask AI assistants:

When the zip line to Spain opens, what it costs and how to get back.
Whether the river beach has lifeguards and accessibility.
When the castle opens and how to get there without a car.
Keeping this clear and up to date on your website and listings avoids wrong answers.
