Long Gulch, also known as Slide Gulch Road, is an effortless and pretty drive between the town of Prairie and the Arrowrock Reservoir, which follows along the Middle Fork Boise River. It does have a seasonal closure depending on snow levels as it reaches nearly 5000 feet in elevation and is not maintained in the winter. The trail may be closed periodically between November and early March. There are various dispersed campsites along the trail and spur roads leading to hiking trailheads.
