This is information about cycling and mountain biking in Grand Teton National Park and the Jackson Hole, Wyoming, vicinity for De Anza College Outdoor Club trips. It can’t be kept completely up to the minute, so check with Rangers for the most current rules and any trail closures, especially due to animal activity.
Bike riding in Grand Teton park can be as safe as at home, but has a few risks different and greater than in other places.
Please note that vehicles on the road will be very busy watching the scenery, not you on your bike.
Riding on the main highway with it’s often narrow shoulders could be dangerous.
Vehicles kill dozens of animals every year in the Tetons and Yellowstone despite warnings:
The park service warns:
“Some roads in the park predate today’s bicycling popularity. Most roads have a paved marked shoulder, providing limited space for safe bicycling. Some roads have only a very narrow shoulder, or lack one altogether. Use extreme caution.” . . .”Riding a bicycle abreast of another bicycle on paved roads within the park and parkway is prohibited. Ride single file for your safety and compliance. During low visibility and between sunset and sunrise, bicyclists must display a white light or reflector from the front and a red light or reflector from the rear. Drivers are often distracted when driving through the park, ride defensively.”
Don’t bike or jog/run by yourself, it is safer to bike in groups since there are very large, potentially dangerous and unpredictable animals potentially everywhere.
Please, no trail running Grand Teton National park: “Trail running is strongly discouraged; you may startle a bear.” Glacier National Park: “Trail running is discouraged as there have been an increasing number of injuries and fatalities due to runners surprising bears at close range.”
It is safer to enjoy a bike ride on a designated bike/roller blade/walk path like the Teton multi-use pathway, than on the road/highway with drivers looking at scenery instead of you on your bike, and there is an 8 mile long pathway from South Jenny Lake to the Moose Visitor Center, then under the highway and into town along the east side of highway 191/89/26. This section is usually closed Dec. 1 to April 30 to protect migrating elk.
Please walk your bike in the parking lots. Bikes yield to others.
Only NON-MOTORIZED METHODS of transportation are permitted on the multi-use pathway. Persons with physical disabilities may use electric and battery operated transportation. Pets (except guide dogs) are prohibited and the pathway is closed from dusk to dawn for wildlife and public safety. The pathway is open whenever it is predominantly free of snow and ice.
Whoooooa, stay alert. . . occasionally a driver gets lost and ends up driving on the pathway.
To be safe wear a helmet at all times (all ages of riders).
Announce your presence before passing (you could say something like ‘passing on your left’ as you approach a pedestrian, slower biker, or someone stopped by the side of the pathway).
Park rules say do not approach wildlife, stay 100 yards from bears or wolves and 25 yards from other wildlife including nesting birds. If you have an accidental, surprise or inadvertent closer encounter with wildlife you must remove yourself to those distances.

Studies suggest that rates of sudden encounters with bears are much higher among cyclists than hikers, due to the speed at which bikers come up on animals. Some of these incidents have been fatal to the human. Read on to find ‘grizzly bears and cyclists’ below.
For your safety hiking, the Rangers warn “Always carry bear spray and know how to use it,” which applies to cyclists as well.

Grand Canyon National Park (AZ)
Runner Charged, Struck By Bull Elk
A long-time park resident was running on a trail behind the Albright Training Center between Center Road and the Grand Canyon School around 6 a.m. on September 19th when he was charged by a large bull elk. He saw that the elk was rubbing its antlers on a tree and acting aggressively, so he took evasive action and ran off trail into the woods around it. The elk pursued, though, and knocked him down. He was able to get away and flagged down a passerby, who called for assistance. The runner suffered scrapes and bruises along with an ankle injury and was transported by ambulance to the Flagstaff Medical Center. Park wildlife biologists and rangers will spend the next several days in the area where the incident occurred and will attempt to move the elk out of the area using aversive conditioning. Although encounters with bull elk have not been common within the park, rangers are reminding residents and park visitors that it is rutting season for both deer and elk. During this period, generally September/October, these animals become increasingly aggressive and may become angered by any intrusion into their territory. Elk, which can weigh as much as 1,000 pounds, have been known to injure or kill people who approach them. [Submitted by Maureen Oltrogge, Public Affairs Officer]
Bikes or other wheeled vehicles are not allowed on hiking trails or in the backcountry on or off trail. They are only allowed in the park on paved and unpaved roads where cars can legally go, on designated bike/walk pathways and on the Colter Bay Marina breakwater. Keep reading to find legal mountain biking trails outside of the park.
The park says about safe biking: ride single file on the right hand road shoulder, use hand signals to communicate with drivers, wear a helmet at all times (all ages of riders). Please also wear highly visible clothing. Bright colored, preferably reflectively enhanced, clothing is best.
The Park Service does not recommend biking at night , but if you do bike before sunrise of after sunset you will need a foreward facing white light/reflector and a rear facing red light/reflector.

The Teton Wilderness and the Gros Ventre Wilderness are much of the land to the east of Grand Teton National Park up to Yellowstone and to the east of and below the town of Jackson. Go to:
http://www.fs.usda.gov/btnf/ click on recreation, then bicycling, then the appropriate section.
Please remember bikes yield to hikers and horses, hikers yield to horses.
The local Forest Service office reminds us:
YOU ARE TOO CLOSE TO WILDLIFE IF:
· The animal stops feeding or resting.
· The animal starts moving either toward or away from you.
· The animal starts panting, huffing or making unusual sounds.
· The animal begins pawing the ground or swinging its head.
· Neck hair or feathers stand up.
· The animal appears nervous, uneasy or stressed.
If you notice these signs you are disturbing the animal and it is time
to slowly move away. The safest way to view wildlife is through
binoculars or spotting scopes.”
Grizzly bears and cyclists
The following info is from a study of the effect planned road improvements could have on animals in the park. The study of bears mentioned is from Canadian parks, but the same incidents could happen to cyclists anywhere.
“Some information on cyclist encounters with grizzly bears is available from Herrero and Herrero (2000), from which the following information was taken. In North America, 33 records were found for cyclist encounters with grizzly bears in which the bear responded aggressively. Five of these occurred on roads used by cars and the remaining occurred on trials or nearby.
In most cases grizzly bears charged or chased cyclists. In 12% (4 of 33) of encounters, cyclists were injured by grizzly bears; in 75% of these cases(3 of 4), injuries were serious (requiring more than 24 hours in a hospital).
The majority (22 of 33) of encounters occurred in Banff and Jasper National Parks, where mountain biking is allowed on some trails.
Ninety-five percent of encounters in which distance was estimated, the cyclist first became aware of the bear at less than 50 meters, “which Herrero (1985) defined as a sudden encounter.
Importantly, while not conclusive, the data suggest that rates of sudden encounters with bears are much higher among cyclists than hikers.
“Indeed, in Canada’s Kluane National Park, park managers state that “Mountain bikers travel quickly and quietly on the trails. As a result, they are much more likely to have surprise encounters with bears and other wildlife, than hikers, and horses” (Kluane National Park 1997).
Most of the encounters documented by Herrero and Herrero (2000) and discussed above occurred on dirt trails, where bicycles would be expected to travel slower and make more noise than they would on a paved pathway.”
Grizzlys can run as fast as 30 mph in short distances.
