Sesimbra & Arrábida

Where this is

Sesimbra sits on the south-western tip of the Setúbal peninsula, facing south, tucked into a bay between two forts. To the north rises the Serra da Arrábida, grey limestone and green scrub up to 500 metres; to the west, the coast runs wild as far as Cape Espichel, land's end for anyone coming from Lisbon. All of it has been a Natural Park since 1976 and a UNESCO Biosphere Reserve since 2025, and the sea in front is the Professor Luiz Saldanha Marine Park, the first in mainland Portugal.

The town has lived off the sea for eight hundred years. First up on the hill, in the castle, for fear of pirates; then down here, once the seventeenth-century forts made the beach safe. The boats still go out at night from the fishing harbour and the catch reaches the market in the morning. That is why you eat here as you do in few other places: line-caught fish, landed the same day.

Getting there

By car, forty minutes from Lisbon over the 25 de Abril bridge, then the A2 and the N378. By bus, Carris Metropolitana links Lisbon to Sesimbra in one to one and a half hours. Inside the town you walk; for Cape Espichel and Azóia you need a car, or the local bus. In summer, park in the car parks at the entrance to the town and walk down.

When to go

Spring and early autumn are the best months: calm sea, good light, few queues. July and August are for the beach and the boat, with the town full. In winter, a clear day at Cape Espichel or up at the castle is worth the trip, and the paths are empty.

What to see, and how to do it on your own

We made five free audio tours, guided by GPS, so you can walk all this at your own pace. You scan a QR code or tap “Start”, the tour opens straight away on your phone (nothing to install), you put your headphones on and the audio plays by itself at each stop. They are in six languages.

Rules of the park

You are in a protected area. Stay on the paths, pick no plants and no fossils, light no fires, fly no drones without permission and take your litter with you. At sea, there are zones where fishing and anchoring are forbidden. On the cliffs, keep back from the edge: the limestone crumbles. In the natural pools, only with a calm sea and a low tide.
