This well-manged regional reserve was set up to ensure a supply of drinking water for Buenaventura. The crystal-clear river attacks many local tourists from Cali, who come for a picnic, a swim or rubbing down the river. At this site you can find many Choco lowland and Foothill species such as Rose-faced Parrot, Blue-fronted Parrotlet, Five-coloured Barbet, Striped-billed Aracari.
