Praia do Carvalho: The Algarve Beach Through a Rock Tunnel

Praia do Carvalho is a small cove in the municipality of Lagoa, between Benagil and Carvoeiro, and the only way onto the sand is through a tunnel dug by hand into the cliff. It sits just off the Seven Hanging Valleys trail, below the Alfanzina lighthouse. Here’s what to expect before you head down the steps.

Quick answer: Praia do Carvalho is a small, unsupervised cove about 10 minutes’ drive from Carvoeiro. Park for free near the Clube Atlântico development or on the clifftop, then walk down a long, steep flight of steps and through a narrow rock tunnel. There are no lifeguards, toilets or cafés, so bring water, food and shade, and arrive early in summer.

Why go

Carvalho is one of the smallest beaches on the Lagoa coast, and the way in is half the appeal. A dark passage through the rock opens onto a V-shaped cove of golden sand, closed in by high limestone cliffs with grottos and rock shapes along their base. On a calm day the water is clear enough for good snorkelling.

It fits neatly into a walk on the Seven Hanging Valleys trail, and makes a quieter alternative when Praia da Marinha and Benagil are packed.

What makes it special

• The tunnel: cut by hand through the cliff, it’s narrow, unlit and uneven underfoot. Look at the walls for fossils in the rock.
• A sheltered cove: cliffs on three sides frame the sand and give some shade as the sun moves round.
• Snorkelling: clear water on calm days, with small fish and grottos along the foot of the cliffs.
• The clifftop: the Alfanzina lighthouse stands just to the west, with wide views along the coast.

The steps and the tunnel

From the clifftop, a long staircase leads down the cliff to the tunnel entrance. The steps are steep and uneven, and sand on them makes them slippery, so wear trainers or sandals with grip rather than flip-flops. The tunnel itself is short but dark: let your eyes adjust, use a phone torch if needed, and give way to people coming the other way.

This rules out buggies and wheelchairs, and it’s hard going with bad knees. The climb back up is tougher on a hot afternoon, so pack light. The beach isn’t signposted, so save it in a map app first.

Size, crowds and the tide

The cove is small, and there’s less dry sand as the tide comes in. In July and August it fills by late morning, with no overflow beach next door, so arrive early. From October to May there’s usually room to spread out.

Check the tide before you go, and pick a time around low tide for the most space. See today’s tide times for nearby Carvoeiro on tides.watch; the tide turns at almost the same time all along this stretch of coast.

Swimming and snorkelling

On calm days the water is clear and the rocks at both ends hold small fish, so bring a mask and snorkel. The seabed is shallow at first, then drops quickly, so watch children closely and don’t swim far out. There are no lifeguards at any time of year: Carvalho isn’t on the official 2026 list of bathing beaches for Lagoa, which also means it has no Blue Flag.

The Benagil cave is close by along the coast, but it isn’t a swim from here. Since August 2024 nobody may swim to the cave or land on its beach, and kayaks may only go in with a licensed guide. Read the Benagil cave guide for the current rules, or book a guided kayak tour to see the caves from the water. For more paddling, see kayaking in Portugal.

The Seven Hanging Valleys trail

Carvalho lies on the Percurso dos Sete Vales Suspensos (the Seven Hanging Valleys trail, LGA PR1), which runs about 5.7km one way along the clifftops between Praia da Marinha and Praia de Vale Centeanes. Walking west from Marinha, you reach Benagil first, then Carvalho, then the Alfanzina lighthouse before the path drops to Vale Centeanes. Use the steps down to the beach, not any of the informal paths over the cliff edge.

A good morning: walk from Marinha, coffee at Benagil, a swim at Carvalho, lunch at Vale Centeanes, then a taxi back. See the Seven Hanging Valleys trail and the best hikes in the Algarve.

Getting there

• By car: about 10 minutes from Carvoeiro and roughly an hour from Faro airport on the A22, which has been toll-free since January 2025. From the Carvoeiro side, park near the Clube Atlântico development and follow the path to the staircase. See getting from Faro airport and car hire in Portugal.
• On foot: along the clifftop trail from Benagil, a short walk, or from Vale Centeanes past the lighthouse.
• By taxi: from Carvoeiro or Lagoa. Phone signal can be patchy below the cliffs, so arrange your pick-up before you go down.
• By bus: local buses serve Carvoeiro and Benagil, but they’re infrequent. See getting around the Algarve.

Parking

Parking is free but limited and unregulated, with roadside spaces near the entrance, around Clube Atlântico and along the clifftop. In July and August they can be hard to find after mid-morning. Don’t block driveways, and leave nothing on show in the car.

Facilities

There are none: no café, toilets, showers, sunbed hire or lifeguards. The nearest cafés and toilets are at Benagil, Vale Centeanes and in Carvoeiro. Bring:

• Plenty of water and some food.
• Shade, such as a small umbrella, as the cove gets full sun in the middle of the day.
• A mask, snorkel and water shoes for the rocks.
• A bag to take your rubbish home.

When to go

May, June and September are the best months: warm enough to swim, with space on the sand. In July and August, arrive before about 10am. Mornings are usually calmest for snorkelling, and later in the day the cliffs shade parts of the beach. In winter it’s a pleasant stop on the trail, though the sea is cold. See the best time to visit the Algarve.

Tips

• Rockfalls: don’t sit right under the cliffs, and stay back from the edges on the clifftop.
• Children: the steps, deep water and lack of lifeguards suit older children better. See kid-friendly Algarve beaches.
• Photos: frame the sea through the mouth of the tunnel. See the Algarve’s best photo spots.
• Drones: flying is restricted along much of this coast, so check the rules first.

Plan it: Carvoeiro makes the handiest base, minutes from the trail and the coves: see places to stay in Carvoeiro. To see the caves and arches from the sea, compare Benagil boat tours. See also where to stay in the Algarve and the best Algarve boat trips.

FAQ

How do you get down to Praia do Carvalho?

Walk down a long, steep staircase from the clifftop, then through a short tunnel cut in the rock. It’s the only way in from land, and it’s not suitable for buggies or wheelchairs.

Does Praia do Carvalho have lifeguards?

No. It isn’t an official bathing beach, so there are no lifeguards or Blue Flag, even in summer. Swim only on calm days and stay close to the shore.

Is there parking at Praia do Carvalho?

Yes, free roadside parking near the entrance, around Clube Atlântico and on the clifftop, but spaces are limited, so arrive early in July and August.

Can you swim from Praia do Carvalho to Benagil cave?

No. Swimming to the Benagil cave has been banned since August 2024. See it from a licensed boat or guided kayak tour, or look down through the hole in its roof from the clifftop trail.
