Natural Bridge Bike Trail

The Natural Bridge bike trail is 2.5 mi (4km) round-trip ride and begins just south of the Bridge Bay marina off the Grand Loop Road. Most of the trail follows an old paved road (mostly disintegrated but fairly level with an elevation gain of 317 feet). The trail meanders through the forest then joins a service road and continues west. There is no biking beyond the service road portion of the trail. ONLY HIKING is allowed from this point to the Natural Bridge. The short but steep switchback loop trail to the top of the bridge starts in front of the interpretive exhibit. The natural bridge is a 51 foot (18 m) cliff of rhyolite rock cut through by Bridge Creek. To protect this fragile resource, the top of the bridge is closed to off-trail hiking. Exercise caution along the creek bed for wet and slippery rocks. Mountain bikes are recommended. Alerts: Be alert for bears: both black and grizzly bears forage in this area. The trail is generally closed until early summer while bears feed on spawning trout in Bridge Creek. Federal regulations require you to stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from bison and all other wild animals. Wear bear spray while riding. Inquire at the Fishing Bridge Visitor Center for opening dates and other closures.
