The Best Algarve Boat Trips: Benagil, Dolphins and Grottos

The best of the Algarve is seen from the water: sea caves, golden grottos, hidden beaches and dolphins playing alongside the boat. There are dozens of trips to choose from, so here are the best Algarve boat trips, where they leave from and what they cost in 2026, plus the Benagil rules you need to know.

Quick answer: for Benagil Cave, take a short boat from Portimão or Armação de Pêra (from about €20) or a guided kayak from Benagil beach. In Lagos, explore the Ponta da Piedade grottos by small boat or kayak. For wildlife, book dolphin watching (about €30–45). In the east, go island hopping in the Ria Formosa from Faro or Olhão.

How to choose your trip

The Algarve coast changes a lot from west to east, and so do the boat trips. Pick the trip by what you want to see, then pick the town it leaves from.

• Caves and cliffs: the central coast between Portimão and Albufeira, with Benagil in the middle, and Ponta da Piedade near Lagos.
• Wildlife: dolphin trips run from most marinas. For birds, the Ria Formosa lagoons in the east are best.
• Calm water: the Ria Formosa is sheltered behind its barrier islands, so it suits young children and anyone who gets seasick.
• A day out: catamaran cruises with lunch and swim stops are the easiest choice for groups and families.

1. Benagil Cave boat tours

The Algarve’s most famous trip: a boat into the cathedral-like cave with the hole in its roof. Since 2024, no one can land on the beach inside or swim into the cave, and the time boats can spend inside is limited. Boats run from several towns:

• Benagil beach: the shortest trips, just minutes to the cave.
• Portimão: cheap and frequent, often from €15–30, passing the caves of Carvoeiro on the way.
• Armação de Pêra: about 15 minutes away, from around €20, with fishermen’s boats right off the beach.
• Albufeira: from about €35, longer trips.
• Lagos: speedboats take about 25 minutes each way (1h45–2h total), from about €25.

What to expect

The rules that came into force on 13 August 2024 cap each boat’s visit inside the main cave at two minutes, and they limit how many boats can be inside at once (reports say three small boats or one larger one). So the cave itself is a short, busy moment. The real value of a good trip is the coast around it: a string of smaller caves, arches and empty coves between Carvoeiro and Armação de Pêra that you can’t reach on foot. Longer trips show you many more caves than the quick runs from Benagil beach.

In summer, the small car park at Benagil fills early, so a trip from Armação de Pêra or Portimão is often easier.

See Benagil boat tours. Full details in our Benagil Cave guide.

2. Benagil by kayak or paddleboard

Paddling into the cave is magical, but since 2024 it’s only allowed on licensed guided tours (renting a kayak and going alone is banned in the cave area). Tours leave from Benagil beach, last 1.5–2 hours and cost about €30–40, visiting several caves along the way. Go early when the sea is calm. See Benagil kayak tours.

You don’t need experience: guides give a short lesson on the beach, and most tours use stable sit-on-top kayaks for two. You will get wet, so wear a swimsuit and use a dry bag. Check the operator’s minimum age if you have children.

3. Ponta da Piedade grottos (Lagos)

Small boats from Lagos marina weave through the arches, grottos and rock stacks of Ponta da Piedade, with the skippers pointing out shapes in the rocks. About 75 minutes from around €20–25, or longer trips with snorkelling. Kayak tours are fantastic too. See Ponta da Piedade trips.

The headland is a jumble of honey-coloured sandstone pillars just south of Lagos, with a lighthouse on top. Small boats are the point here: the bigger ones can’t fit through the narrow arches. Many trips also pass the coves of Dona Ana and Camilo. The wooden stairs down to Praia do Camilo have been closed since storm damage in the winter of 2025–26, so a boat is the only way to see it close up for now. You can also walk the clifftop paths afterwards for the view from above. See our Ponta da Piedade guide.

4. Dolphin watching

Common and bottlenose dolphins are regularly seen off the Algarve, and many operators work with marine biologists. Trips last 1.5–2.5 hours on fast RIBs or larger boats. Prices are about €30–35 from Albufeira and Vilamoura, and €40–45 from Lagos and Portimão. Sightings are common but never guaranteed; some trips offer a free retry. See dolphin-watching trips.

RIBs are fast, open boats that bounce a lot, so they are not ideal for back problems, pregnancy or very young children. Good operators keep their distance and don’t chase the animals.

5. Albufeira coast and caves

From Albufeira marina, trips head west to Benagil and the sea caves of the central Algarve, or east along the red cliffs, with swim stops. See Albufeira boat trips.

Because Albufeira is further from Benagil, westbound trips are longer than those from nearer towns: expect about 2 to 3 hours.

6. Catamaran and sailing cruises

Bigger, more comfortable boats for half-day or day cruises, often with a barbecue lunch, drinks and swimming stops. Great for families and anyone worried about seasickness. Sunset cruises run from Lagos, Portimão, Albufeira and Vilamoura. See Algarve catamaran cruises.

Catamarans are too big to go inside the caves, so you see them from the outside, and some include a transfer to a smaller boat or a swim near the cliffs. In return you get space, shade, a toilet and a smoother ride. Check whether lunch and drinks are included before you book.

7. Ria Formosa island hopping

In the east, the calm lagoons of the Ria Formosa natural park are perfect for relaxed trips to car-free islands, with birdwatching (look for flamingos and spoonbills) and beach stops.

• Faro to Ilha Deserta: a ferry of about 45 minutes from the pier by Faro’s old town, around €10–12 return.
• Island-hopping tours from Faro or Olhão visit two to four islands, from about €40.
• Eco tours with a biologist explain the oyster beds and wildlife.

The Ria Formosa is a long chain of sandbank islands, channels and salt marsh running for about 60km along the coast from west of Faro to Manta Rota, beyond Cacela Velha. It is a different Algarve: flat, quiet and full of birds. Ilha Deserta (also called Barreta) is the most southerly point of mainland Portugal. If you prefer to do it yourself, cheap public ferries run from Olhão to Armona and Culatra, and from Tavira to Ilha de Tavira. See the Ria Formosa natural park guide.

Tips

• Go in the morning: the sea is usually calmer and the light in the caves is better.
• Seasickness? Choose bigger boats or calm-water trips like the Ria Formosa, and take tablets before you board.
• Bring: sun cream, a hat, a towel, water and a dry bag or waterproof phone case.
• Weather: trips are cancelled if the sea is rough, so book with free cancellation and keep a backup day.
• Only use licensed operators, especially for Benagil, as fines are heavy and unlicensed boats are being cracked down on.
• Best season: May to October, though many trips run all year in good weather.
• Book ahead in July and August: the best morning slots sell out days in advance. In spring and autumn you can often book the day before.
• Getting there without a car: Lagos, Portimão and Albufeira all have bus links, and Lagos and Portimão have stations on the Algarve line. The A22 motorway along the coast has been toll-free since January 2025.

FAQ

Can you swim or kayak into Benagil cave on your own?

No. Since August 2024 swimming into the cave, landing on its beach and renting a kayak or paddleboard to go in alone are all banned. You can still go in by licensed boat or on a guided kayak tour.

Which town is best for a Benagil boat trip?

Benagil beach gives the shortest trips, Armação de Pêra and Portimão are close and cheaper, and Lagos and Albufeira suit you if you’re staying there. Longer trips show you more caves along the way.

Do boat trips run in winter?

Many do, on calm days, though there are fewer departures and more cancellations. Book with free cancellation and keep a spare day.

Will I definitely see dolphins?

Sightings are common but never guaranteed. Some operators offer a free second trip if you see none, so ask before you book.
