More ways to explore the area's outdoor wonders
You step off the quay in Sesimbra and the harbor’s chatter fades as the boat slips into blue water. The cliffs of the Arrábida rise like folded pages, and the hull noses toward shaded mouths cut into limestone where light and tide trade places. Waves probe the caves with steady patience; sunlight slips through narrow openings and paints the rock in sudden, cool blues.

Arrive Early
