Buckskin Mountain State Park, State park on Colorado River near Parker, Arizona, US.

Buckskin Mountain State Park is a public recreation area near Parker, Arizona, with a second developed area called the River Island Unit or River Island State Park. Both units have shoreline on the Colorado River and views of the Buckskin Mountains. The park offers camping and water recreation.

The park was created in 1967 on land within the ancestral territory of the Mohave and Chemehuevi peoples along the Colorado River. The region served as a home for these communities long before becoming a modern recreational facility.

The park serves as a gathering place where visitors connect with the Colorado River landscape that has been home to Indigenous peoples for centuries. Families and groups use the riverside setting for recreation while being part of the same land that shaped the region's history.

The park lies along the Colorado River near Parker, reached by road from the town about 16 km away. Two developed areas, the main park and the River Island Unit, both have shoreline for camping and water recreation. Summer daytime temperatures average around 26 °C but can climb far higher, so carry water and sun protection.

The Lightning Bolt Trail is a steep short walk that leads to elevated viewpoints overlooking the river's blue-green water and surrounding desert landscape. Many visitors overlook this path, preferring instead to stay in the flatter areas along the shore.
