Swimming:
Castelo do Bode (castle of the billy goat) lake is 300m away. The water is refreshingly cool in the summer and it is wonderful to swim in it.
There are plenty of fluvial beaches to choose from and there is a map in the house. They are all very close.
Fishing is also possible and there are boat hire facilities in Ferreira do Zêzêre, approximately 20 mins by car.
Cycling:
The Ribatejo countryside is unexplored and there are plenty of tracks you can follow. There are two bicycles in the garage that are freely available for guests' use. It's an ideal way of exploring the countryside.
Sightseeing:
Tomar, the historical town of the Order of the Templars is a short drive away. The Convent of Christ on the hilltop is a must. The Sanctuary of Fátima, holy place of pilgrimage is around 30kms away. Castelo de Almoural, set on a tiny island of the Tagus was built as a fortress in 1171. Lovely spot for a picnic.
Torres Novas has many fine churches within its castle walls.
There are many small villages around the lake that are worth visiting such as Dornes, a UNESCO protected village and Constância, right on the banks of the River Tagus.
