We read that Alcoutim has a fluvial beach; we searched for it, but didn't see.
Lots of boats, a nice tranquility by the river, music coming from Spain just across, a nice scenery, but no idea about the beach.
In Alcoutim it is very easy to greet Spain. The houses on the other side of the river are already spanish! The town is called Sanlucar de Guardiana. I don't know if there is a possibility to cross the border here by boat, but the other town also looks interesting with the castle and the windmills.
Edit: The walkable city guide downloadable via the Camara Municipal is refering to a boat by which it is possible to get to the other side. For the guide, check my tip.
In case you have seen the Menhir do Lavajo before (see other tip) or you are planning to drive there afterwords, I recommend you to visit the museum in the castelo. Here you will find the other menhir which was brought here from the Lavajo site. There is a reference to it on the information plate at the Menhir do Lavajo I outside town.
Otherwise the castle is more like a park, less then a fortress, but with the museum worth to be visited when being around.
Let me know if the weblink does not work anymore!
Location, etc.: Alcoutim may be quiet, its unique location makes it worth a detour! A river trip is the ultimate way to see the Guadiana, but if you have rented a car, take a drive along the river.
Not an activity tip but a passivity tip: place yourself somewhere on the quay, purchase your preferred beverage, bring either your favourite book, your favourite person, your camera, a pair of binoculars, your walkman, all of the above, or just repeat your favourite mantra.
A lot of effort has been put into restoring the castle (13th century, built on top of an even older ruin), which had fallen into disrepair and was being used as a slaughterhouse. Although there is not that much left of the fortress itself, the views from the walls are beautiful. Tickets are not cheap but give you access to other museums as well.
Located by the river, the church of "S.Salvador" was initially built in the 14th century, enlarged in the 16th in Renaissance style and restored in 1949, respecting the old image.
The village of Sanlucar de Guadiana is only a small stretch of water away in Andalucia, Spain. There is no bridge, but the boatman will take you across the river for just one euro.
