Railroad Tunnel River Road

  • Featuring 36 Mountain Bike Trails and 18 Road Rides in and around Buena Vista & Salida, Colorado – beginner to expert, town to summit, smooth tarmac to extreme singletrack.

The Railroad Tunnel River Road runs north from downtown Buena Vista and follows the Midland Railroad grade along the Arkansas River. The road passes through several short railroad tunnels and offers excellent views of whitewater rapids, piñon pines and the Collegiate Peaks – Mt. Princeton (14,197 ft.), Mt. Yale (14,194 ft.) and Mt. Columbia (14,073 ft.). Since the ride is an out and back route, make the ride any length you want – just turn around when you start to tire. This is a great route if you want to ride out of town and have a picnic lunch.

Trailhead Access: At the stop light on US 24 in downtown Buena Vista, turn east on Main Street. Drive east on Main to the Buena Vista River Park. Pass the baseball field, keeping left, and park near the wooden building with bathrooms. If you are camping and want a shower, look for signs pointing to the coin-operated showers in the building as you enter the River Park.

Railroad Tunnel River Road Mileage Log

0.0 Retrace your driving route to Main Street.
0.5 Turn right on N. Colorado and follow it out of town. It changes to CR 371.
2.3 Cross the Arkansas River. This is a pretty area with huge rocks.
2.6 The road turns to smooth dirt. This is the Midland Railroad grade.
3.2 Railroad Tunnels – the first of four. These one-lane tunnels allowed the engines to pass through. Give cars the right of way since they can’t see you easily in the dark. The River Road leaves the river for a few miles after the final tunnel.
3.7 Bob’s Rock, a rock climbing area, on your right. Elephant Rock on your left.
6.0 Continue straight on CR 371.
6.8 The Railroad Bridge Recreation Site on your left. They have pit toilets here. This is a day-use fee area so if you plan to spend time here, register and pay at the self-service kiosk. The road narrows and closely follows the river. This section of the river includes part of the “Numbers”, a class V section of the whitewater. These rapids are an excellent spot for a close, dry view of whitewater action. This section has nice picnic spots along the road – find a spot you like and picnic.
10.1 Turn left at the end of the River Road and ride out on the bridge over the Arkansas. This is the turn-around spot for the out and back ride. Nice job!


We want you to have a safe and enjoyable trip into Colorado’s backcountry. Be prepared it could be a long walk out. Be sure to read this list of equipment you should bring on your ride along with tips to make your biking trip more enjoyable.


The Colorado backcountry is popular – bikers, hikers, motorcycle riders, hunters and equestrians use the trail system in the Arkansas Valley, and everyone wants a private piece of heaven. Even if you don’t agree with everyone’s motives or methods of travel, please treat them in a courteous manner.


If you require search and rescue services, it can be costly. Buy a Colorado Outdoor Recreation Search and Rescue (CORSAR) card to protect yourself. Funds from the CORSAR program go into the Colorado Search and Rescue (SAR) Fund. If a CORSAR card holder becomes lost or injured in the backcountry, the Colorado SAR Fund pays eligible search and rescue expenses.
