The Benagil Sea Cave, located in a small fishing village 3 hours from Lisbon, is arguably one of the most interesting tourist attractions in the world.
Accessible only by boat, the cave contains a peculiar domed ceiling and natural oculus shaped by wave attrition and Miocene limestone built-up over 20 million years ago.
Hiding under the intricate arches of the grotto is a secret beach with golden, fine sand. The only way to get to the beach is to kayak, paddleboard, or swim.
The Algarve of Portugal’s southernmost region has an abundance of sea caves, but the Benagil Sea Cave with its clash of intricate rock formations, secluded beach, and radiant shades from amber is the most spectacular.
