The Ruby Jack Trail - a 16 mile "Rails to Trails" project that starts at Carthage, MO and goes through the towns of Oronogo and Carl Junction, and extends all the way to the Kansas State Line.
The Ruby Jack Trail is now officially open to the public! All 16 miles of the trail are currently open for hiking and mountain biking, but the trail is very rough and a lot of work needs to be done before it can be used by all types of bikes. Please be careful when hiking or biking on the trail. Remember, use of any motorized vehicle on the trail is expressly forbidden. Please report any use of motorized vehicles on the trail to the JTC (contact@joplintrailscoalition.org) or the Jasper County Sherrif's Dept.
