Experience nature at her finest along the cottonwood-willow draped banks of the Hassayampa River. Our 730-acre preserve is a birder's paradise, with some 280 species of birds living, nesting, or migrating along the riparian corridor.Trails at the Hassayampa are self-guided, leading you along the lush river bottoms, across the river's floodplain, through majestic cottonwood-willow forests and dense mesquite bosques (the Spanish word for forest) found only near desert waterways. Continuing along the trail is a loop around Palm Lake where waterfowl, otherwise uncommon in the desert, are a major attraction.
