As of yesterday, bicyclists willing to brave the unpredictable elements of spring in Yellowstone National Park can ride along any of the 49 miles between the West Entrance and Mammoth Hot Springs.
Areas of the road now open include the West Entrance to Madison Junction, Madison Junction to Norris Junction, and Norris Junction to Mammoth Hot Springs.
Tomorrow, the road from Norris Junction to Mammoth Hot Springs will close to all travel from 8:00 am to 4:30 pm to allow for heavy equipment operations and then will reopen at 4:30 pm.
As conditions permit, bicycles may be allowed on two additional park roads. That includes the East Entrance to the east side of Sylvan Pass and South Entrance to West Thumb.
Bikes are not allowed on the remaining interior park roads until they start to open to motorized vehicle access at 8:00 am Friday, April 16th.
