Those in Lisbon who like the sea but aren’t fans of the sand also have a place that suits them. The Oeiras Ocean Pool is filled with water from the sea and is split into two sections: one for kids and the other for adults with four diving boards. To make the most of the sun and heat, all you need to bring are your beach shorts. There are sun loungers, changing rooms, umbrellas and a bar serving light meals. With parking and a fantastic view of the marina and mouth of the Tagus, this is undoubtedly one of the best options when you don’t feel like going to the beach but fancy a refreshing swim during your holidays in Lisbon.
