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.

Located 15 miles west of Yellowstone National Park, this high mountain lake is the kind of place fishermen dream about.
