Idaho Centennial Road/Trail


The 900-mile Idaho Centennial Trail weaves through the most scenic portions of Idaho’s wild country, from high desert canyonlands in southern Idaho to wet mountain forests in North Idaho. Visitors will cross many mountains, streams and rivers in between. It was designated as the official state trail during Idaho’s Centennial year in 1990. Since that time, only a few people have actually completed the Idaho Centennial Trail, revealing the challenge and time-commitment involved. This area is comprised of mainly two track-roads and is enjoyed by a variety of recreationists. Two-wheel drive vehicles are sufficient to reach the Bruneau Canyon Overlook and the top of the Murphy Hot Springs Grade. However, if you are traveling from Murphy to Bruneau Canyon Overlook, a four-wheel-drive vehicle with clearance is recommended.
