Benagil is famous for its caves, the coastal walk to several beaches and the lighthouse. It is a stunning walk from Benagil to the famous Praia de Marinha.
Inside of the famous Benagil Cave is a beach which is much bigger at low tide. Swimming into the cave can be quite challenging especially during rough seas! Swimm with a board and in a group not alone. Check the tides first before swimming! Anyhow, you need to be an experienced swimmer. An alternative is a boat trip to the existing caves at the Algarve.
Avoiding Crowds and Best Time for Swimming
Best months for swimming are June to September with pleasant sea temp. July and August are the peak season; Prices increase and beaches are pretty crowded. The Portuguese school holidays start mid-June and last roughly until the first week in September depending on the school.

Bring a neoprene shorty for longer swimming though the sea temperature is around 21°C / 70°F during summer until October and 20°C / 68°F in June.
