There are no established campsites or amenities—no toilets, water, picnic tables, or fire rings—so campers must be fully self-sufficient and follow Leave No Trace principles. No reservations are needed, and camping is free, though a Wyoming State Parks day-use fee may apply. The area is accessible by vehicle but not suitable for large RVs or those needing hookups. Expect expansive lake views, open skies, and minimal crowds. Ideal for boaters, anglers, and solitude seekers. Best visited late spring to early fall for mild weather and full lake access.
