The Portinho da Arrábida is one of the most beautiful beaches in the Portuguese coastline, with bright thin sand and luminous crystalline waters, contrasting with the luxuriant vegetation of the greenish Arrábida Mountain, situated in the astonishing Arrábida Mountain Natural Park. The beach is usually quite crowded during summer months, much frequented by families that find here the perfect calm waters for children, and shelter from the strong coastal winds. It is also quite frequented by divers, sport fishers and other sport practitioners.
