Covão dos Musaranhos. A very pleasant space next to the Óbidos Lagoon, it has a picnic area, barbecue and public toilets (unfortunately almost always closed). There is also a bar restaurant with a pleasant terrace (they do not serve dinner).

The Arnóia River rises in the Serra de Todo o Mundo and flows for 30 km before flowing into the Óbidos Lagoon. A dam was built about one and a half kilometres from Óbidos, in the Horta Valley, whose reservoir was used to irrigate the area's crops.

Covering around 35 hectares, the Bacalhôa Buddha Eden garden was created in response to the destruction of the Giant Buddhas of Bamyan, in what was one of the greatest acts of cultural barbarity, erasing from memory masterpieces of the late period of Gandhara Art. Among Buddhas, pagodas, terracotta statues and various sculptures carefully placed among the vegetation, it is estimated that more than 6 thousand tons of marble and granite were used to build this monumental work. The central staircase is the focal point of the garden, where the golden Buddhas calmly welcome visitors. In the central lake, you can see KOI fish and sculpted dragons rising from the water. You will also have the opportunity to observe around 600 hand-painted terracotta soldiers, each one unique, some of which are buried, just as they were 2,200 years ago.
