Tunnel Drive Trail

Tunnel Drive Trail ranks among Canon City's most beloved outdoor attractions, combining natural beauty, railroad history, and easy accessibility on a scenic 2.5-mile paved path. The trail follows the historic railroad bed of the Denver & Rio Grande Western Railroad, passing through three hand-carved tunnels that transported passengers along the Arkansas River in the late 1800s. The trail begins at the parking area on Tunnel Drive and follows the canyon rim at a gentle grade—a remnant of its railroad origins where steep grades were impractical for steam locomotives. This makes the trail accessible to hikers, joggers, cyclists, and families with strollers. The paved surface is maintained year-round, though winter ice can make portions slippery. Three tunnels punctuate the journey, each carved through solid granite by railroad workers over a century ago. The longest tunnel extends approximately 200 feet and provides a cool respite on hot summer days. Natural light filters through from both ends, but the interiors grow dark enough to appreciate the engineering effort required to create these passages. The trail offers exceptional views of the Arkansas River flowing through the canyon below. At several points, you can look down at the river's green waters winding through the granite walls. Wildlife viewing opportunities abound—keep your eyes on the opposite canyon walls for bighorn sheep, which frequently traverse the rocky terrain. Golden eagles, prairie falcons, and various raptors ride the thermals above the canyon. Historical markers along the trail explain the Denver & Rio Grande Western's role in opening the Royal Gorge region to tourism and commerce. The railroad war between the D&RG and the Santa Fe Railway for rights through the Royal Gorge is one of the most colorful chapters in Colorado railroad history. The trail is free and open year-round from dawn to dusk. Parking is available at the trailhead on Tunnel Drive. Restroom facilities are located at the parking area. The round-trip distance of approximately 5 miles typically takes 1.5 to 2.5 hours depending on pace and photo stops. Early morning and late afternoon offer the best lighting for photography and the coolest temperatures in summer. For a longer adventure, the trail connects to additional hiking routes in the area. Bring water, wear sun protection, and stay on designated paths to protect the fragile canyon ecosystem.
