About
Overview
Willow Flat is a popular campground, located on the banks of the Cub River, in southeastern Idaho. It sits in a pretty valley, surrounded by scenic mountain views, at an elevation of 6,300 feet. Visitors enjoy fishing the river and exploring numerous forested trails.
Recreation
The Cub River provides great fishing for wild cutthroat and hatchery rainbow trout.
Numerous trails begin within the campground, including a 1/2-mile nature trail to Sam Parkinson Spring.
The multi-use Cub River Trail also begins at the campground, offering great hiking, mountain and dirt biking, as well as off-road vehicle and horseback riding. The trail accesses the Highline Trail, the North Fork of St. Charles Creek and the Cub River Guard Station.
Facilities
This large campground contains six group campsites than can accommodate 24 to 100 people. Numerous single-family campsites are available at the campground as well.
Some single and group sites have picnic shelters. A few single sites must be accessed via footbridges over the river from the parking spur.
Amenities available at the campground include vault toilets and drinking water. An amphitheater with bleacher seating and a cement platform is located at group site G03. Roads and parking spurs within the campground are gravel.
Natural Features
A mixed forest of pines, spruce and hardwoods provides partial shade and beautiful scenery. The banks of the Cub River are lined with dense stands of willow, a favorite food of local moose. Deer and elk are often seen in the area as well.
