Benagil Cave is one that deserves the attention for nature wonders lovers. Like a frog in a well, you look up to see clear blue sky through its circular inner grotto right in the middle of the cave. Another opening to the cave is the huge collapsed roof where the sea water occasionally wash ashore into the cave. All these holes have allowed abundance of sunlight to enter the cave, breaking its usual impression of a dark and humid cave.

Benagil Cave is also known as the Sea Cave. This type of cave is primarily formed from the constant erosion made by the action of the wave on the sea. Although sea caves can be found almost on every part of the world, this one Algarve, Portugal, however, is a real gem of natural beauty.

Apart from admiring the magnificent view this cave has to offer, people also come here for its excellent water activities such as kayaking and swimming in the clear waters.
