Benagil is a small cove and former fishing hamlet in Lagoa, on the Algarve’s cliff coast, and the starting point for trips to the Algar de Benagil, the sea cave with a round hole in its roof. You can see the inside of the cave only from the water, on a licensed boat trip or a guided kayak or paddleboard tour. Since 13 August 2024 nobody may land on the cave’s beach, swim in or rent a kayak without a guide there (rules still in force as of October 2026). You can also look down into it from the clifftop path.

What it is and why it’s famous
The Algarve’s soft, golden limestone is riddled with sea caves, arches and stacks, but the Algar de Benagil is the star. The sea has eaten into it from the side and rain from above, leaving a domed chamber with two openings to the sea, a small sandy beach at the back and a round skylight in the ceiling. When the sun is high, a column of light falls through the hole onto the sand and the water glows turquoise.
That photo made it world famous, and the crowds that followed (boats jammed inside, swimmers crossing the boat lane, people climbing on the rocks) led the authorities to bring in rules in 2024. Benagil village itself is tiny: a slipway, a little beach between cliffs, a few restaurants and the tour kiosks. For the wider coast, see our Algarve travel guide.
The rules for visiting the cave (as of October 2026)
The Portimão harbour master (Capitania do Porto de Portimão, part of Portugal’s National Maritime Authority) set navigation rules for the Benagil caves in Edital 19/2024, in force since 13 August 2024, amended by Edital 9/2025:
- No landing on, or using, the beach inside the cave, for private visitors and for tour companies.
- No swimming into the caves, and no reaching them on floats, inflatables or other swimming aids.
- No renting kayaks without a guide in the caves area. Guided kayak tours need one guide kayak for every six visitor kayaks.
- Caps on how many boats and kayaks may be inside at the same time and on how long each visit lasts. In practice a motorboat stays only a few minutes; kayaks and paddleboards get a little longer.
- No navigation between sunset and sunrise.
- The 2025 amendment separates boat traffic, with different entrances for rigid motorboats and inflatables, and requires life jackets near rockfall areas.
- Operators who break the rules face fines from €300 up to €216,000.
The area also lies within the Pedra do Valado marine natural park (Parque Natural Marinho do Recife do Algarve), so take everything you bring back with you.
Ways to see the cave
By boat
The quickest option. Licensed boats leave from Benagil beach itself and from Carvoeiro, Armação de Pêra, Portimão and Albufeira. From Benagil the trip is short; from further away it becomes a coastal tour that takes in other caves and arches on the way. You see the skylight from the water, but only for the few minutes each boat is allowed inside. Boats go in only when the sea allows.
By kayak or paddleboard
The slower, more memorable way, and the one that gives you longest inside. Guided tours start from Benagil beach, with a short paddle along the cliffs to the cave and usually stops at smaller grottoes nearby. You need calm seas and some basic fitness. Calm mornings are best, before the wind picks up and the boat traffic builds.
From the clifftop
The free option. The Seven Hanging Valleys trail (Percurso dos Sete Vales Suspensos, PR1 LGA) runs along the clifftops from Praia da Marinha past Benagil and above the cave, where you can look down into it through the skylight. It is about 5.7 km one way to Vale Centeanes. Stay well back from the edges: the limestone crumbles.
When to go and how long to allow
Allow half a day: an hour or two on the water plus time on the beach or the clifftop path. The light inside the cave is best from late morning to early afternoon, when the sun is high enough to shine through the hole. Summer seas are usually calmest, but July and August bring the most people. May–June and September–October are the sweet spot. Book early in your stay so that if the sea is too rough, you have time to try again. Benagil beach had lifeguards from 1 June to 30 September in 2026.
Getting there
A car is easiest. Benagil sits between Carvoeiro and Armação de Pêra, off the coast road, and its car park on the clifftop fills by mid-morning in summer. The walk down to the beach is short but steep. The A22 motorway across the Algarve has been toll-free since 1 January 2025. Vamus regional buses link the main towns but are slow and infrequent for Benagil itself, so from Carvoeiro or Lagoa a taxi is often more practical. If you book a boat trip from Portimão, Albufeira or Armação de Pêra, you can skip driving to Benagil altogether.
Safety
- Wear the life jacket you are given, and keep it on near the cave walls.
- Don’t try to swim to the cave from Benagil beach. It is banned, and the short swim crosses a busy boat lane.
- On the clifftop, stay well back from the skylight and the cliff edges, and respect any fences; rockfalls happen along this whole coast.
- Obey the beach flags: red means no entering the water, yellow means no swimming.
Combine it with
Praia da Marinha, one of the Algarve’s most photographed beaches, is a short drive or a clifftop walk to the east. Walk the Seven Hanging Valleys trail early in the morning, take your boat or kayak tour, and finish with a swim at Marinha or at the village beach in Carvoeiro. Ponta da Piedade near Lagos is the other great cliff-and-cave landscape of the western Algarve.
Benagil cave FAQ
Can you still go inside Benagil cave?
Yes, by licensed boat or on a guided kayak or paddleboard tour. Since 13 August 2024 you can’t step onto the beach inside, swim in, or rent a kayak without a guide in the caves area; those rules were still in force as of October 2026.
Can you swim to Benagil cave?
No. Reaching the caves by swimming or on floats has been banned since August 2024, and the stretch from the beach is busy with boats.
Is a boat or a kayak better for Benagil cave?
A boat is quicker and suits families and non-paddlers, but each boat is inside only for a few minutes. A guided kayak or paddleboard tour takes longer, gives you more time inside and is more fun, but needs calm water and some fitness.
What is the best time of day to visit Benagil cave?
Late morning to early afternoon, when the sun shines through the hole in the roof. For kayaks, calm mornings are best.
Can you see Benagil cave from above?
Yes. The Seven Hanging Valleys clifftop trail passes above the cave, and you can look down through the skylight, keeping well back from the edge. It is free.

Researched and last reviewed by TravelerCenter on 3 October 2026. Cave rules come from the National Maritime Authority’s Portimão harbour master notices (Edital 19/2024 and 9/2025) as published by the CCDR Algarve and the Lagoa e Carvoeiro parish council; the 2026 bathing season from Portaria 204-A/2026; the A22 toll change from Law 37/2024; the trail from Lagoa council information. The exact caps on boats and minutes inside are in the harbour master’s notice, which we could not open directly. Access rules change, so check with your tour operator before you go.
