The sanctuary has eight well-laid-out nature trails traversing it. The length of the nature trails ranges from 500 metres to 5 kilometres. There are six watchtowers in the sanctuary. Also there is one 'tree top;' it is situated about 20 metres high on a tree overlooking a waterhole. Both the Gal and Talpona rivers of Canacona Taluka originate from the sanctuary. At the entrance to the sanctuary there is an ecotourism complex that houses the nature interpretation centre, cottages, toilets, library, reception area and rescue centre, canteen and range forest office.

One air-conditioned suite is there called Peacock Cottage, a beautiful villa in nicely set-up surroundings with its own courtyard.
The sanctuary is situated about 3 km from the ecotourism complex by road but the forest area is continuous, the early morning walk in sanctuary area is rewarding and can witness rich bird life of the area. Sighting big animals is difficult because of dense vegetation. sighting is difficult only when animals come in open sighting of animals is there. Amid the treetops is a unique type of watchtower in the sanctuary. The watchtower is entirely balanced on trees and the climb is quite steep. The watch tower 20 m above ground level. It overlooks a water hole where animals come to drink.
