Overview: Willow Creek Campground is located along the Middle Fork of the Boise River Forest Service (FS) road 268 and the north end of the Arrowrock Reservior. There are 9 campsites at the campground. A stay at the campground enables guests to enjoy all the beauty and recreation offered along the river and reservoir. Weather is usually good from mid-May through late September and is easily accessible by car in good weather, although the road is sometimes rough and the drive can be seemingly long. Checking with the District on road conditions before heading out is recommended. Natural Features: Wildlife watchers may want to look for deer and elk. Waterfowl, eagles and osprey are attracted to the river. Recreation: There are several trails in the area including trail #189 beginning near Cottonwood Campground, leading to Bald Mountain Peak. Check the Idaho City Ranger District Motor Vehicle Use Map (MVUM) for trails in the area that are open to hikers, equestrians, mountain bikers and off-road vehicles.

Big game hunting is a popular activity in season.
Road to get to Willow Creek was a little rough, about 15 miles on a bumpy dirt road. The camp ground was great. No reservation, first come, no fee. Had a bathroom for the entire campground (maybe 9 spots), picnic table, fire pit with grill, small steel table. There was a water pump but it was locked. Great views, clear water, good fishing! If you’re willing to make the drive this is a great spot.
This campground is accessible by a long dirt/gravel road, with drop offs on one side to the reservoir. Just be prepared for that and drive safely / don't be jn a hurry.
Beautiful location close to Boise, river is claiming and relaxing. A few places to walk around and explore. No reservations, first come first serve location.
