1. Benagil Cave – Algarve

Topping our list is probably what would be considered the most famous cave in Portugal, and the only sea cave on our list! Located between Armacao de Pera and Carvoeiro, you will find Algar de Benagil! An incredible sea cave, carved out by years of wind and water, it is one of the top places to visit in the Algarve!

The second, the Lido Pool, is a man made structure, in which you won’t find sharp rocks and makes for safer swimming, particularly with the kids! You’ll also find a lounging area, bar and shower/changing room, which makes for a relaxing day by the sea! There are many tours you can take to visit Porto Moniz. We find however that making your way there allows you to explore the volcanic pools at a more leisurely pace.
