The hills surrounding Sesimbra offer fabulous walks and scenic views, part of the Arrábida National Park. Sesimbra is a popular diving location close to Lisbon and the most famous dive site is the wreck of the River Gurara, a Nigerian cargo ship, that sunk in 1989 with the loss of 45 sailors. Besides professional fishing and sports fishing (mainly of swordfish), the most significant revenue in Sesimbra comes from tourism. The town is known for its beaches, fish restaurants and nightlife.
Residents of nearby Lisbon flock here on weekends to relax on its long sandy beach and dine in the excellent beach-front fish and seafood restaurants following an appetizing evening stroll along the town’s extensive promenade. A popular choice of dish is the locally-caught swordfish (espadarte) which is cooked to perfection on the many charcoal grills lined along the pavements.
