Lima Dam Road takes you through the picturesque Centennial Valley, stretching from Lima on I-15 to the junction of North Valley Road and Blacktail Road. This easy trail offers pleasant scenery. Although the water in Lima Reservoir may not be suitable for swimming, remnants of cabins built around the same time as the dam in 1934, transport you back in time and ignite curiosity about life in this area a century ago. While camping is not available along this road, it serves as a gateway to numerous fantastic getaways along the Gravelly Range Road.
