Camping under a stand of mature ponderosa pine and juniper is a major attraction and the long beach is popular with sunbathers and swimmers. A nature trail provides excellent bird watching opportunities. There are no ADA accessible campsites at this park. Pets on leash are allowed. Tribal Fishing License Required.
