You will have no trouble finding things to do here. The Anderson Ranch Reservoir has something for everyone, from experienced anglers to novice hikers. While hiking, boating, and fishing are the primary activities at the reservoir, there is also camping, biking, hunting, and lots of opportunity to try out different water sports.
With the wide expanse of water and the beautiful surroundings, Anderson Ranch Reservoir is a popular place for boating and waterskiing, especially during the summer months.
North of the Reservoir are two little campgrounds; Elks Flat and Dog Creek. It is only a short drive from these campgrounds to a boat ramp on the shores of Anderson Ranch Reservoir. While there is a collection of campgrounds around the Reservoir, the level sites, good drinking water, and abundant shade found at Elks Flat and Dog Creek campgrounds make them very popular with motorhome and recreational vehicle campers.
Camp Creek Trail is a moderately difficult 6 mile hiking/biking trail in the area. Elevation gain is 1,500 feet. Drive up Fall Creek Road about 3 miles then turn right on to FS Rd. 128 and go about a mile to reach the trailhead.
The fishing on the Anderson Ranch Reservoir is some of the best in the state of Idaho, offering plentiful kokanee, Rainbow trout, small mouth bass, and more. An experienced Idaho fishing guide can help you navigate the Anderson Ranch Reservoir area and provide fishing tips for certain hot spots and what bait or lure techniques to be used or find a spot to simply throw a party and have fun. Fishing Licenses are required.
