Suitable for most people with basic mobility; able to climb a short ladder to swim.
Set sail from Cascais on a private Dufour 460 for a three‑hour Atlantic cruise that passes Estoril, Carcavelos, and the dramatic cliffs of Boca do Inferno. Swim in sheltered bays, enjoy optional onboard meals, and take in Lisbon’s skyline from the water.
The bow parts the Atlantic with a soft, salty hiss; Lisbon’s skyline hangs low on the horizon like a distant promise. Onboard a Dufour 460 Grand Large, up to ten people trade the marina’s tiled promenade for an open-deck rhythm where wind and wake set the pace. You leave Cascais harbor, the town’s 19th‑century mansions shrinking behind you, and head west along a coastline that alternates between wide sandy beaches and jagged cliffs that seem to test the Atlantic’s patience.

Mornings are usually calmer; take preventative seasickness medication if you’re prone to motion sensitivity.
Even on overcast days UV reflects off the water—use high‑SPF sunscreen and a brimmed hat.
Wear soft‑soled, non‑marking shoes to move safely on wet decks and avoid damaging the boat.
Follow crew instructions when swimming or anchoring to protect seagrass and marine life.
Cascais transformed from a working fishing village into a royal coastal retreat in the 19th century; maritime routes have long linked it to Lisbon through the Barra de Lisboa.
Operators are encouraged to avoid anchoring on seagrass beds and to minimize single‑use plastics to protect local marine habitats.
Protects your footing on wet decks and protects boat surfaces.
Keeps skin protected from reflected UV over the open water.
