Benagil Cave by Boat: The Current Rules and How to Visit Safely

Benagil Cave is one of the most photographed places in Portugal: a huge sea cave with a natural “eye” in its roof and a golden beach inside. Its popularity has also brought crowds and safety concerns, and since August 2024 new rules control how visitors can access it. Here’s what you need to know before you go.

The current rules

The maritime authorities introduced the following rules for the Benagil caves:

• No landing on the beach inside the cave. Visitors and companies are not allowed to step onto or use the sand inside.
• No swimming into the cave. Swimming from the beach or from a boat into the caves is prohibited.
• No flotation devices. Paddle boards, inflatables and similar can’t be used to reach the cave.
• Kayaks only with a guide. Renting a kayak and going alone is no longer allowed. Guided groups must have one guide for every six kayaks.
• Limits on time and numbers. There’s a maximum visit time and a limit on how many boats and kayaks can be inside at once.

Operators who break the rules face heavy fines, so always book with a licensed operator.

Why the rules changed

Benagil became so popular that, in summer, the cave and the beach inside were often overcrowded, with swimmers, kayaks and boats all in the same small space. There were regular rescues of swimmers caught by currents. The new rules aim to protect visitors and this fragile coastline.

Don’t rely on old social media posts

Many videos and blogs still show people swimming in or relaxing on the beach inside the cave. That is no longer allowed. Always check the current rules with your operator for your date.

Weather and sea conditions

The cave is open to the Atlantic, so swell and wind can make access unsafe, even on a sunny day. Your skipper will always decide on the day what’s possible, putting safety first. Stay flexible, as the coastline around Benagil is stunning whatever happens.
