If you venture out to Santiago do Cacém, a few kilometers inland from Sines, you have another opportunity to visit some castles, have lookout viewpoints from the top of mountains and see some old windmills.
The visit to Santiago do Cacém will not take long, and is best if you have your own transportation. The town is very small and most of the attractions, if not in the center, are on the top of the surrounding hills. There is a small tourist information building in the center.
Sines’ main attraction for the tourist is its coast. But the inland, more than visited, deserves to be enjoyed. On foot, on bicycle or by car, there are many interesting places to discover. In the north, the Sancha Lagoon area is an ecological treasure connected to the Santo André Lagoon’s ecosystem.
Pessegueiro Island is one of the municipality’s most interesting places, either from the historic or from the landscape point of view. The island has ruins of a Roman port and in the cliff in front of it stands the Pessegueiro Fort. A channel separates the island from mainland, crating a beautiful beach with good conditions for windsurfing and spear-fishing. During summer it’s possible to visit the island on organized boat trips from Sines and Porto Covo.
The municipality's southern coastline, preserved almost to its wild state, is protected by natural park. There are some of the finest Portuguese beaches, small bright sand sheets among huge rocks creating an ambience of intimacy and exclusiveness. The two main urban centres, Sines and Porto Covo, are charming little towns, calm, rich in history and offering superb gastronomy, based on the fish and seafood captured nearby.
