Poorly maintained, some sections dangerous because of landslides due to the water and rain. If you like to bike in dense vegetation and get your face smacked, this is for you. If else, take the road nearby

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).
