Located approximately 14 miles eat of Basalt, CO, in the White River National Forest, Little Mattie Campground is situated on the Ruedi Reservoir at an elevation of 7800 feet. Sites are open to the starry nighttime skies and access to the lake and trails. It sits amid a mixed conifer forest and offers an ideal setting for guest seeking recreation and relaxation.
Little Mattie has 19 standard sites suitable for tents, trailers and RVs. There is a maximum length of 30 feet for RVs & trailers. The sites are equipped with picnic tables, campfire rings and bear boxes (food storage lockers). Guests also have access to vault toilets and drinking water, but electrical hook-ups are not available.
Renown for its fly fishing, Frying pan River flows below Ruedi Dam. Here, large rainbow, brown, cutthroat and brook trout are plentiful in an area nicknamed the “toilet bowl.” The fish feed on Mysis shrimp, a small freshwater shrimp stocked in the lake. The stretch of rive from below the dam down to the confluence of Frying Pan and the Roaring Fork River has been designated as Gold Medal Waters by the Colorado Wildlife Commission. Special regulations in this area include fishing only with artificial flies and lures, and releasing all trout except brown trout, with a limit of two fish over 14 inches. For hikers and bikers, the Ruedi Trail, located north of the reservoir, climbs to the top of Red Mountain. The trailhead is located 200 feet north of the Jeep trail near the boat ramp and parking lot. This eight mile trail gains over 3,000 feet in elevation, leading hikers to a spectacular panoramic view of the area. Boating, swimming, and water skiing are all possible. Interpretive programs are popular activities.
Take I-70 west of Denver to Glenwood Springs Exit 116, Highway 82 to Basalt. At Basalt, take Frying Pan Road 15 miles to the Ruedi Complex Entrance.
