John Day Fossil Beds Classic is a 118.4 mile loop trail located near Mt Vernon, OR and is only recommended for very experienced adventurers. The trail is primarily used for road biking and is accessible from June until October.
I am an avid cyclists and have lived in Mt Vernon and the John Day area for 16 years. I know of no such 118.4 mile loop called John Day Fossil Beds. If it exits I would like to ride it.
