Cottonwood Campground

A stay at the Cottonwood Campground enables guests to enjoy all the beauty and recreation offered around the Middle Fork Boise River and Arrowrock Reservoir.

This tiny campground hosts 3 campsites.

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.

Natural Features:

The campground is situated just north of the reservoir along Cottonwood Creek. There is at a switchback of Forest Service (FS) roads 268 and 377. It is located less than a mile along FS road 377.

Wildlife watchers may want to look for deer and elk. Waterfowl, eagles and osprey are attracted to the river.

Recreation:

Cottonwood Trail begins nearby, leading to Bald Mountain.

Arrowrock Reservoir is a premier fishing destination in southwest Idaho. It offers excellent trout fishing for rainbow and cutthroat trout. There are also good swimming holes. Big game hunting is a popular activity in season.

The Middle Fork Boise River is just north of the campground and also offers great fishing.
