Find Campsites

ATTENTION: Please note beginning with 2015 stays, Idaho State Park fees will charge different rates for resident and non- resident customers. This change requires the collection of unique primary site occupant information (name, address, and telephone number) for all sites. This includes cabins, campsites, yurts and group facilities. Customers booking multiple sites under one name should expect a follow up call from IDPR staff requesting primary occupant information.

Massacre Rocks State Park was established and classified as a Historical Park in 1968 and opened to the public in 1970.
