Which boat trip along the Arrábida coast is right for you?
Pick by harbour: Sesimbra for caves and snorkeling, Setúbal for the Sado dolphins, Portinho da Arrábida for a slow sail. Part of the Arrábida coast road, the Figueirinha to Galápos stretch, has been shut to cars since 2023, so a boat is often the only way into the hidden coves and sea caves under the Serra da Arrábida.
Where do the Sesimbra boat trips go?
Sesimbra boats run west along the Arrábida Natural Park to hidden beaches and sea caves, with snorkeling stops in clear water. This is the trip most people mean when they look up a boat trip in Sesimbra: about three hours, gear included, right along the edge of the park.
Can you see dolphins from Setúbal?
Yes. A resident pod of bottlenose dolphins lives year-round in the Sado estuary off Setúbal and Tróia, one of the few places in Europe to see wild dolphins on a short boat trip. Boats from Setúbal pair the estuary with the turquoise Arrábida bays. Sightings are frequent but not guaranteed, and the water is usually calmest first thing in the morning.
Is the Portinho trip quieter?
Yes. Portinho da Arrábida is where the sailing trips leave, drifting along the coastline with swim stops in secluded coves. They run slower and quieter than the fast RIB boats, good for a lazy afternoon anchored in a cove.
When should you go, and what should you bring?
The season runs roughly May to October, when the water is warmest. Even then the Atlantic stays cool, around 18–20°C by late summer and colder the rest of the year, so pack a layer for the ride back. The dolphins are in the estuary all year, so a Setúbal trip still works outside high season. In July and August the cave and snorkeling trips sell out days in advance, so book before you arrive, and note which harbour your trip leaves from: Sesimbra, Setúbal and Portinho are three different ports.
