Boat Sea Tour with Submarine Vision

Board at Pier nº1 of Sesimbra’s Harbor and discover an unforgettable tour aboard the APNEA vessel.

The route includes 3 strategic stops, perfect for observing marine life up close through the underwater windows.

Along the way, you’ll enjoy the stunning Sesimbra coastline, hidden beaches, and the breathtaking greenery of the Arrábida Mountains, with the chance to spot marine species in their natural habitat.

A highlight of the tour is the famous Ribeiro do Cavalo Beach, often called the “most Thai-like beach in Portugal.” With its white sand, crystal-clear waters, and unique scenery, it’s the perfect spot for truly unforgettable moments.
