Boat Tours in Cascais

6 tours · €38–€50 per person · ★ 5.0

Boat tours in Cascais swap the busy marina for the open Atlantic, and the coastline pays you back for it. Heading out by water is the easiest way to see the cliffs west of town, the sandy curve of Guincho and the rugged edge of the Sintra-Cascais coast you can't reach on foot.

When you compare Cascais boat tours, start with what you want from the afternoon. A sunset cruise points you toward Cabo da Roca with a drink in hand as the light drops; a short coastal cruise glides past Boca do Inferno and the bay's quiet coves. Surf-focused trips lean active, chasing the swell off Guincho. We'd book a private charter so the skipper slows down for swimming stops, and a small-group sail if you'd rather meet people. Most run half-day or shorter, easy to slot around a Sintra day trip.
