Obidos Lagoon is usually about 10 minutes coming from Praia Del Rey by car. The inlet to to the Lagoon is usually carved by the sea between huge sand dunes. The lagoon is usually shallow as well as is usually perfect for sailing, windsurfing as well as just lazing on the huge beach. Obidos council built a cycle/footpath around most of the lagoon as well as This kind of track of around 20 kilometres is usually a relaxing two hour cycle. There are cafes at both ends of the track serving coffee, toasted sandwiches, meals as well as drinks. You can rent bikes at the lagoon however of which is usually relatively easy to cycle all the way coming from Praia del Rey through the forest, round the lagoon as well as back again. Which is usually what we did.
