Benagil Cave is one of those places that's famous before you ever visit it, as a Windows desktop wallpaper, as a "top 10 beaches in the world" thumbnail, as a five-second shot in a Telugu movie. Getting there properly means not just showing up for a boat trip, but walking a chunk of the Seven Hanging Valleys Trail first, one of the Algarve's best coastal hikes in its own right.
The full trip: driving in from Faro, the cliff-top hike, the boat tour, and inside Benagil Cave itself.
Starting at Praia da Marinha
The day began with a rental car drive from Faro to Praia da Marinha, one of the trailheads for the Seven Hanging Valleys Trail and, on its own, routinely ranked among the most beautiful beaches in Europe. The name Algarve itself has Moorish roots, it comes from the Arabic al-Gharb, meaning "the West," a name given to this stretch of coast during the centuries of Moorish rule over the Iberian Peninsula before the Reconquista. It's a small detail that changes how the whole region reads: this coastline has been described as the western edge of someone else's map for a very long time. The cliffs here do most of the talking anyway, golden limestone stacks, sea arches, and water in a turquoise that doesn't look real in photos until you're standing above it.
The Seven Hanging Valleys Trail
The Seven Hanging Valleys Trail (Percurso dos Sete Vales Suspensos) runs along the clifftops between Praia da Marinha and Praia de Vale de Centeanes, threading past hidden coves that seem to appear out of nowhere. It's not a difficult hike, but it's not a flat one either, wooden staircases drop down into little valleys and climb straight back out the other side, and the natural cliff-edge paths get close enough to the drop that it keeps you paying attention. Every so often the trail opens onto a rocky overlook with sea caves visible far below, and at one point it passes directly above Benagil Cave itself, you can look straight down through its natural roof opening before ever seeing it from the water.
Benagil Beach and the boat tour
The trail eventually drops down to Benagil Beach itself, small, packed, and tucked directly beneath the cliffs, with the cave's dark entrance visible from the sand. From here the options split: kayak in, paddleboard in, or take a speedboat tour. I went with the speedboat, mainly for time, though in hindsight a kayak with a waterproof action camera strapped on would probably get better footage from inside the cave itself, worth planning for if there's a next time.
Inside Benagil Cave: the wallpaper, in person
Then the cave itself. Benagil Cave is a sea cave with a collapsed section of roof, leaving a near-perfect circular opening that drops a shaft of daylight straight onto the small sand floor and shallow pool inside, the exact image that's been a default Windows desktop wallpaper for years, and instantly recognisable the moment the boat pulls in. It's also had a moment of Tollywood fame: this cave was a shooting location for the Telugu film Liger, which made stepping inside it feel a little less like a random beauty spot and a little more like a place that had already shown up in a movie I'd actually seen.
The Submarine Cave, the Elephant Cave, and a high-speed finish
Benagil isn't the only cave on this stretch, the boat tour wound through several more sea caves and rock formations carved out of the same limestone coastline. The Submarine Cave is a dark, narrow pass-through tunnel the boat threads directly through, and the Elephant Cave is named, unsurprisingly, for a rock formation that genuinely reads as an elephant's head and trunk from the right angle. The tour wrapped up the way these things should: a high-speed run back across open water, spray coming off both sides of the boat, before docking back at Benagil Beach.
Back on land: a dip, and the rest of the trail
Back on the sand, it was a quick bite to eat and a dip in the ocean, cold enough to notice immediately, refreshing enough to be worth it after a morning of hiking and boat spray. From there the hike continued along the clifftops, past spots where local cliff divers were taking turns jumping into coves, more hidden beaches tucked into the rock, and viewpoints looking down over the resort developments that line this part of the coast.
Wrapping up: 6 kilometres and a flight to catch
By the time I called it, I'd covered roughly 6 kilometres of the trail, not the full Seven Hanging Valleys route end to end, but enough to see most of what makes it worth doing, with only a few hours left before a flight. An Uber back to the parked rental car, a quick drop-off, and straight to the airport, the kind of tight, slightly rushed ending that a lot of one-day coastal stops turn into when the itinerary is this packed.
Practical tips for Benagil and the Seven Hanging Valleys
- Getting there: Praia da Marinha and Benagil Beach both work as trailheads; a rental car with paid parking near either is the easiest option.
- Cave access: Benagil Cave is only reachable by water, kayak, paddleboard or a guided boat tour. Landing inside the cave itself is generally not permitted; boats and kayaks view it from the water.
- Camera tip: A waterproof action camera on a kayak beats a speedboat for footage inside the cave, since kayaks can get closer and linger longer.
- Footwear: Proper hiking shoes, the trail has wooden staircases, loose gravel, and cliff-edge paths with no barriers in places.
- Timing: Go early. Both the trail and the beach get crowded fast once the day-trip boats and coach tours arrive.
A cave that's been a screensaver for half the internet and a film set for Tollywood turned out to be exactly as good in person as advertised, but it was the walk to get there, past seven valleys' worth of arches, hidden coves and cliff divers, that made the day. The cave is the postcard; the trail is the actual trip.
