The Abandoned Railroad Bed Bike Trail is near Yellowstone National Park's North Entrance and offers an 8-mile (13 km) round-trip adventure along a historic railway corridor. Starting northwest of the Heritage and Research Center in Gardiner, Montana, the trail parallels the Yellowstone River and provides views of Electric Peak and opportunities to observe local wildlife such as pronghorn, elk, and bison. When you start out, you will need to walk your bike a short distance from Old Yellowstone Trail Road until you reach the old railroad bed that comprises the bike trail.
Mountain or gravel bikes are recommended because the trail a gently sloping gravel and dirt surface. Due to limited parking at the pullout on the old Yellowstone Road near the Heritage and Research Center, it's good to arrive early. Like everywhere in Yellowstone both black and grizzly bears are active in the area, so be aware and carry bear spray. Additionally, there are sometimes cactus along the roadbed; using tubeless tires with sealant can help prevent punctures.
