With its great domed ceiling, circular skylight and secret beach, Benagil Cave, or Algar de Benagil, has become one of the most photographed places in Portugal. It sits just a short drive east of Carvoeiro, so it is a natural day out for our guests. Before you go, though, it is worth knowing that the way you can visit has changed.
The rules you need to know
As the cave grew in popularity, the crowds became a real safety concern, with swimmers, kayaks and boats all packed into a small space. In August 2024, the Portuguese maritime authority introduced new rules to protect both visitors and the cave itself. The main points are:
- No landing on the beach inside the cave, for individuals or tour companies.
- No swimming in and no paddling in on inflatables or other floating devices.
- No unguided kayak or paddleboard rentals in the cave area. Kayak tours must have a guide.
- Limits on the number of boats and kayaks inside the cave at any one time, and on how long each group can stay.
Breaking the rules can lead to fines, and the area is regularly patrolled. Rules can change, so always check with your tour operator before you go.
The best ways to see the cave
By boat tour
The easiest option is a licensed boat tour. Small boats can enter the cave or come right up to its entrances, giving you a clear view of the skylight and beach. Many tours depart from Carvoeiro, Benagil and Portimão and combine the cave with other grottoes and the cliffs around Praia da Marinha. Smaller boats are generally the better choice, as large catamarans cannot get inside.
By guided kayak or paddleboard
For a closer and more peaceful experience, join a guided kayak or SUP tour from Benagil beach. Paddling into the cave under your own steam is magical, and a guide will help you navigate the waves and the rules. This is best for confident swimmers and calm days.
From the clifftop
You can also see the skylight from above on the Seven Hanging Valleys Trail. It is a great view, but please stay well back from the edge, as the rock around the opening is fragile.
Tips for a great visit
- Go early: the first tours of the day are calmer and less crowded.
- Check the sea: tours are cancelled in rough conditions, so keep your plans flexible.
- Visit out of season: spring and autumn are quieter and the light is still beautiful.
- Book a small group: you will get more time and better photos.
Seen the right way, Benagil Cave is every bit as breathtaking as the photos suggest, and it is just one of countless coastal wonders on the doorstep of Carvoeiro.
