Benagil Sea Cave – Beach Inside A Cave – Algarve, Portugal

The Benagil Sea cave is part of an old system of caves which is found in the Algarve region, the southernmost region of continental Portugal.

Algarve is, without a doubt, the perfect holiday destination for families, retired people, couples, independent travelers, mixed groups, and backpackers.

Furthermore, this remarkable region in Portugal is not only famous for its warm and calm sea but is also visited for its interesting landscape, fish markets, fishing villages, and friendly locals.

The Benagil caves are situated 150 meters east of the Benagil beach, close to Praia de Benagil.

The sea cave has 2 amazing entrances, a secluded beach of sand, a huge collapsed roof, and a circular inner grotto.

This place is picturesque and has been hewn from the colorful ancient Algarve rock.

Getting to Benagil Sea Cave – Algarve, Portugal

There are three ways to reach this cave:

Swim – the entrance to the cave is literally just around the corner (200m) of the first cliff, hence, it is not a long swim.

However, it is recommended to swim there only if conditions are calm and you’re a strong swimmer. In addition, you should stay far away from the cliffs as a high wave could easily push you into the rocks, and it could result in an injury.

Boat – many boat trips to visit the cave are offered by local companies.

It usually lasts 1 hour, and the price is around 20 euro.

Kayak – only use this option if the sea is quiet enough. Nevertheless, lately, the sea authorities didn’t give permission to rent kayaks to reach this cave.


Although the sea is usually calm, if you take a boat trip, it is advisable to have the utmost care with personal belongings, particularly with your camera and mobile phones.

If you plan to visit, there are several tour options available, including Kayak & SUP Benagil located in Lagoa, Portugal.
