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!

Entrance is cheap at €1.50 and children under three can come for free. The swimming complex has been divided into two pools. The first is the natural pool, where you can swim inside the cave. 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.

Though not exact, it is predicted that the lava tube is between 5000 and 12000 years old, and likely a result of the eruption of the volcano of Sete Cidades or Fogo. You can choose between two different tours. The first is a more easy going route which takes you through 200 meters of tunnels. If you’ve got a bit of an adventurous streak, you may want to take the longer tour, as it will take you deeper and farther in the tunnels!
