Loop through the Santa Fe National Forest to the Valles Caldera National Preserve, a breathtaking expanse of mountain meadow and forest offering premium fishing, hunting, hiking, wildlife viewing, and snow sports by advance reservation. The loop continues through Los Alamos, Fenton Lake State Park, San Pedro Parks Wilderness, Chaco Culture National Historical Park, and a volcanic plug called Cabezon Peak. Short sides trip on lead to the Gilman Tunnels, blasted through rock during the 1920s, and Bandelier National Monument, housing several thousand ancestral Pueblo dwellings within almost 33,000 acres of steep-walled canyons, mesas, and wilderness.
