Go if

Anglers chasing trout and bass on the reservoir will find the boat ramp and shoreline access hard to beat for the price of zero dollars a night. Arrive early on summer weekends; three sites disappear fast.

Skip if

No potable water means hauling your own supply for every meal and drink. With only three sites and no reservations, driving 21 miles from Mountain Home to find it full is a real risk.
