Biking in Yellowstone National Park makes for an incredible way to see the park from a different viewpoint (and get a great workout in!). We recommend biking in the less busy spring season, but even during lighter traffic weeks when the roads are still closed to the public, be aware of your surroundings. Park administrative vehicles will be using the roads, often driving heavy machinery construction vehicles and taking advantage of the time with fewer tourists.
General Safety Tips
Remember that cell phone service is spotty
Wear a helmet
Wear bright clothing easily visible to traffic around you
Carry an extra tube and a pump in case you get a flat tire, as well as other portable bike repair tools
Be aware that emergency medical service can be delayed because park rangers do not regularly patrol spring biking roads
Use front- and back-lights when riding before sunrise or after sunset
Avoid traveling at night
Weather can change quickly and unpredictably; bring extra clothing
Road safety tips
Obey the rules of the road
Be ready to encounter snow and ice on the roads occasionally
Ride on the right side of the road (you should be riding with traffic, not against it)
Some sections have little or no shoulder
Wildlife Safety Tips
Wildlife have the right of way; do not approach, chase, taunt, etc.
Modify your riding route if bison are on the road; do not cause them to run
Remain 25 yards away from all wildlife; stay 100 yards away from bears
Bring bear spray
