The best things to do in the Algarve

Nearly everything worth doing sits within an hour of Faro airport, spread across three landscapes that lie surprisingly close together: the limestone cliff coast of the centre and west, where boats and kayaks slip into sea caves; the Ria Formosa lagoon and its barrier islands in the east; and the green Serra de Monchique rising just inland. Pick one experience from each and you have seen the Algarve at its most characteristic. The finder above filters by all three — this guide goes deeper on each.

Choosing between the boat trips

Boat trips are the Algarve's headline act, and the format matters far more than the price. The signature sight is the Algar de Benagil — a domed sea cave with a skylight and a hidden crescent of sand — and it can only be reached from the water.

• Grotto boats — quick one-to-two-hour hops from Benagil and Carvoeiro straight to the cave. The most direct way in, and the easiest with young children.
• Catamarans and coastline cruises — longer sails from Portimão, Albufeira and Lagos that cover far more shore, usually with a swim stop and shade on deck. Best for a relaxed half-day.
• Kayak and SUP — reach inlets the motorboats can't, on calmer mornings and with a little effort. The closest you get to the rock.
• Dolphin-and-cave combos — push further offshore so wildlife and the caves come in one trip.

As a rule of thumb: take a grotto boat or a kayak for Benagil itself, a catamaran for a leisurely cruise, and a combo when dolphins top your list. Whatever you choose, book a morning departure — the seas are calmest and the light is at its best. Swimming into the cave and landing on its inner beach unsupervised are now restricted for safety, so a licensed operator is the reliable, legal way in.

Prefer to stay dry? The clifftop Seven Hanging Valleys Trail from Praia da Marinha and the boardwalks at Ponta da Piedade show off the same coast on foot, no ticket required.

Dolphins and the Ria Formosa

Dolphin watching

Dolphin-watching trips leave the marinas of Albufeira, Lagos, Portimão and Vilamoura in search of resident common and bottlenose dolphins. Sightings are frequent from April to October but never guaranteed — a reputable operator works to a marine-wildlife code and will tell you so before you book. Mornings tend to be calmer and better for wildlife.

The eastern lagoon: Ria Formosa

Its quieter counterpart sits in the east. The Ria Formosa is a protected lagoon of channels, salt pans and barrier islands running from Faro to Tavira, sheltering seahorses, clams and flamingos. Small-boat and solar-ferry trips from Faro and Olhão reach the islands and the birdlife and make an easy, inexpensive half-day with children.

Inland and the wild coast

Into the Monchique hills

Turn away from the beach and the Algarve changes character within twenty minutes. A jeep safari climbs the cork-oak and eucalyptus slopes of Monchique to Fóia, at 902 m the region's highest point, usually stopping for honey, cheese and a shot of medronho, the local fruit spirit. The thermal village of Caldas de Monchique adds spa baths to the day.

Surf on the Costa Vicentina

The south-west is where the Atlantic arrives with force. Surf schools at Sagres, Arrifana and Praia do Amado on the Costa Vicentina teach beginners through the summer and chase real swell from autumn to spring. Inside a natural park, this wilder shore is also the region's best for walking and for near-empty beaches.

With kids — and what's free

Families are well served. The three big water parks — Slide & Splash near Lagoa, Aqualand at Alcantarilha and the marine park Zoomarine at Guia — each fill a full day from June to September. Gentle, shallow beaches such as Dona Ana, Meia Praia and the eastern island strands suit small children, and a short dolphin or Ria Formosa trip breaks up the beach routine.

A lot of the very best costs nothing. The Seven Hanging Valleys walk is among Europe's finest coastal trails; the boardwalks at Ponta da Piedade deliver those golden stacks without a boat fare; the beaches are free; and sunset at Cabo de São Vicente near Sagres — the south-westernmost point of mainland Europe — is the region's grandest free spectacle. Inland, the walled old quarters of Lagos and Faro, the riverside castle at Silves, and the weekly markets of Loulé and Olhão fill half-days for the price of a coffee.

Where to base yourself, and how far from Faro

Because almost everything sits within an hour or so of the airport, your base shapes your days more than your budget does. Vilamoura and Albufeira sit nearest the tour marinas; Lagos and Carvoeiro are closest to the cave coast; Sagres trades convenience for surf and space; and Tavira anchors the quieter, island-fringed east.

When to go

The Algarve is Portugal's busiest holiday coast, and demand stacks up in July and August. The upside is simple: the shoulder months hand you the same experiences with room to breathe, and often noticeably lower prices. One quirk worth planning around — the sea lags the air, so it is warmest in September; the surf sharpens from autumn into winter; and the caves, dolphins and walking are at their best in spring and early autumn.

Beating the crowds

Popularity is the Algarve's one real drawback, and it is easy to sidestep. Reach Benagil at first light or after 5 pm, when the fleet thins and the light improves. Skip the water parks and marquee beaches at midday in August — go early or late instead. For genuine space, lean east to Tavira, Cabanas and the islands, or west to the Costa Vicentina; both stay calm even in peak week. And book the signature boat and cave tours a day or two ahead in summer, when small-group and early departures sell out on the day.

Beyond the coast: golf and the table

Two more draws deserve a day of their own. The Algarve is one of Europe's premier golf destinations, with 40-plus courses within an hour's drive — the Golden Triangle around Quinta do Lago and Vale do Lobo, and Vilamoura's Dom Pedro layouts, chief among them; winter is prime playing season. And Algarve food and wine runs from Santa Luzia octopus and coastal cataplana to the D.O.C. wines of the Lagoa hills and the morning market at Olhão — a guided food or wine tour is the quickest route to eating where locals do.

How to visit the Benagil sea cave

There is no road to Benagil — you reach the cave only from the water. Here is the reliable way to see it.

1. Pick your craft. Take a short grotto boat from Benagil or Carvoeiro for the quickest visit, a kayak or SUP to get closest to the rock, or a catamaran for a longer cruise that includes it.
2. Book a morning departure. Seas are calmest and the light is best early. In July and August, reserve a day or two ahead, as slots sell out on the day.
3. Go with a licensed operator. Swimming into the cave and landing on its inner beach unsupervised are now restricted, so a licensed guide is the dependable, legal way in.
4. Pack for the water. Bring water, high-factor sun protection, a hat, a dry bag and non-slip shoes; mornings at sea run cooler than the beach.
5. Add the clifftops. Pair the cave with Praia da Marinha and the Seven Hanging Valleys trail to see the same coast from above, for free.
