What to Do in Algarve

The Benagil Cave is a large sea cave with a collapsed ceiling that creates a natural skylight, flooding a tiny interior beach with light. It's become one of Portugal's most photographed spots, which tells you two things: it's genuinely spectacular, and you won't be alone in there. You can only reach the cave by water (there's no land access), so your options are kayak, SUP, or a boat tour. The kayak is the best way to do it because you can enter on your own schedule, stay as long as you want, and actually set foot on the beach inside. Boat tours circle through the cave for about 90 seconds while everyone holds up their phones, which is fine but not exactly contemplative. The paddle from Benagil beach takes about 10 minutes, but the Atlantic swells can make it tricky. If you're not a confident paddler, the guided kayak tours are worth it. Go early in the morning to beat the boat parade.

Ponta da Piedade is the Algarve's most spectacular stretch of coastline, a series of towering golden limestone cliffs, sea stacks, grottos, and arches just south of Lagos. You can walk along the cliff tops for free and the views are already incredible, but seeing it from the water is a completely different experience. Small boats (usually holding 4 to 8 people) depart from the base of the cliffs and spend about an hour weaving through narrow passages, ducking under arches, and poking into caves where the water glows turquoise from the light filtering through. The scale of the rock formations only becomes apparent once you're floating between them. It's one of those "ok I get why everyone talks about this place" moments. The smaller the boat, the better, because the big ones can't fit through the interesting parts.

You've seen this beach in every "best beaches in Europe" list, and for once the hype matches reality. Praia da Marinha is a golden cove framed by towering limestone cliffs, with sea stacks, a natural double arch, and water so clear you can see the bottom from the cliff top. The beach itself is reached by a staircase from the parking lot above, and it's smaller than you'd expect given how famous it is. That's part of the charm and part of the problem: in peak summer it fills up fast and the parking lot becomes a competitive sport. Early morning or late afternoon is the move. The real magic here isn't just lying on the beach (though that's great too), it's the cliff scenery surrounding it. Walk east along the cliff top toward Benagil for increasingly dramatic viewpoints. Low tide reveals more sand and some rock pools worth exploring.

This is the Algarve's best hike and it's not even close. The Sete Vales Suspensos ("Seven Hanging Valleys") trail runs about 5.7 kilometers along the cliff tops between Praia de Vale Centeanes and Praia da Marinha, passing over some of the most absurdly dramatic coastal scenery you'll see anywhere in Europe. Sea arches, golden rock formations, hidden coves way below, the Atlantic crashing into everything. The path is well-marked and mostly flat (it's a cliff walk, not a mountain hike), but some sections get close to the edge and there are no guardrails, so maybe don't do it in flip-flops or after three beers. The whole thing takes about two hours one way, and you can turn around whenever you want if you just wanna do part of it. Go in the morning before the heat kicks in. Late afternoon works too if you want golden light for photos and fewer people.

Cape St. Vincent is the southwestern tip of continental Europe, and standing on the cliffs here feels appropriately dramatic. There's a lighthouse, a drop of about 75 meters to the Atlantic below, and on a clear day the horizon stretches into forever. This is where the ancient Romans thought the world ended, and looking at the raw cliff edge with nothing but ocean beyond, you kinda get where they were coming from. The Fortaleza de Sagres is a few kilometers east, a 15th-century fortress perched on a headland above the sea. Prince Henry the Navigator supposedly ran his navigation school from here, which is poetically fitting given the location. The fortress itself is more about the setting than the interior (there's not a whole lot inside), but the wind, the cliffs, and the crashing waves below make it one of the most atmospheric spots in the Algarve. The whole Sagres area feels different from the rest of the coast, wilder and less polished, with a surfer-town vibe and an end-of-the-world energy that the manicured beach resorts further east just don't have.

Ilha Deserta (literally "Desert Island") is the most southerly point of mainland Portugal, and it lives up to its name. It's a barrier island off the coast of Faro with no roads, no buildings except one restaurant, and a beach that stretches into the distance in both directions. Take the ferry from Faro marina (about 30 minutes), step off, and you're basically on a wild, empty strip of sand backed by dunes. That's it. That's the activity. There's no entertainment complex, no beach bar every 50 meters, no DJ playing house music. Just sand, sea, sky, and the kind of silence you forget exists when you've been doing touristy stuff all week. The one restaurant (Estaminé) serves fresh fish and is actually quite good, but bring your own water, snacks, and sunscreen because once you walk past it, there's nothing. If you want a beach day that feels like the opposite of the crowded central coast, this is it.

Lagos has one of the best-preserved old towns on the Algarve coast, and walking through it is the kind of activity that doesn't feel like an activity until you realize two hours have passed and you've eaten three pastéis de nata. The old town is still partially enclosed by its original walls, and inside it's a maze of narrow cobblestone streets, whitewashed buildings with blue and yellow trim, churches covered in gold leaf, and little squares where people sit drinking cheap espresso like it's a competitive sport. The Igreja de Santo António is worth ducking into for the insanely over-the-top gilded Baroque interior (they apparently ran out of surfaces to cover in gold and had to stop). The Forte da Ponta da Bandeira guards the harbor entrance and gives you nice views back toward town. The marina area is modern but pleasant for an evening stroll, and the restaurant scene in the old town streets is one of the best on the coast, mixing traditional Portuguese with just enough international variety to keep things interesting.

Ilha de Tavira is a barrier island off the eastern Algarve coast, and it's one of the best arguments for leaving the central tourist zone behind. You get there by a short ferry ride from Tavira (or a longer one from the Quatro Águas pier), and what you find is a long, wide, sandy beach that feels like it belongs on a different continent. The western end near the ferry landing has some beach bars, restaurants, and sunbed rentals, so it's not exactly deserted. But walk east for 15 minutes and the crowd thins out dramatically. Keep walking and you'll eventually have the beach pretty much to yourself, just dunes, sand, and the Atlantic. The water on the eastern Algarve is slightly warmer than the western side, which is a nice bonus. Tavira town itself is worth the visit too: a genuinely pretty place with a Roman bridge, whitewashed houses, and a pace that makes the rest of the Algarve feel rushed. Combining the town with a half-day on the island is about as good as it gets for a mellow Algarve day.

The Ria Formosa is a massive coastal lagoon system stretching 60 kilometers along the eastern Algarve, protected as a natural park and home to an absurd amount of birdlife. Flamingos, spoonbills, herons, and a bunch of species that birdwatchers get very excited about. Even if you don't know a flamingo from a pelican, the lagoon is gorgeous: shallow turquoise water, salt marshes, sand bars, and barrier islands creating a landscape that feels nothing like the cliff coast further west. Boat tours run from Faro, Olhão, and Tavira, and most last a couple of hours. Some include stops on the barrier islands (Ilha da Culatra, Ilha da Armona) where you can swim on beaches that are significantly less crowded than anything on the central coast. The whole area has a mellow, local feel that the tourist hotspots lack. If you've spent a few days doing the cliff beaches and want something completely different, a morning on the Ria Formosa is a solid change of pace.

Silves Castle is a massive red sandstone Moorish fortress sitting on top of a hill, overlooking a valley of orange and lemon groves. For centuries, Silves was the Moorish capital of the Algarve, and the castle is the best-preserved reminder of that era in the region. The walls are intact, you can walk along the ramparts with views over the town and the surrounding countryside, and there's a small archaeological museum inside that covers the Islamic and pre-Islamic history of the area. It's not gonna blow you away with interactive exhibits or dramatic recreations, but the setting does the heavy lifting. Silves itself is a quiet, pretty town that most beach-focused visitors skip entirely, which means you get an actual Portuguese small-town experience without the tourist crowds. Grab a fresh-squeezed orange juice from a local cafe (the oranges here are famous and they cost basically nothing), wander the narrow streets, and appreciate that the Algarve existed long before beach tourism.
