Caves are generally dank things — by definition they are all about the underworld — but Benagil is no ordinary spot. This is the shining light of Europe’s caves, a stunning sight that is one of the Algarve’s great visuals. Benagil itself is a little fishing village in Lagoa, but tourism has replaced fishing as the main money driver in the town, and the caves are to thank. A massive hole in the ceiling of the cave allows sunlight to stream in, creating one of the most aesthetically impressive sights in the region. The only access is via the water and there are no shortage of companies on hand to take you in — the water is generally too volatile for swimming to be encouraged.
