A switchbacking railroad grade travels through the east side of Tiger Mountain. Expect mountain bikes for company.

This trail is open to hikers, equestrians and mountain bikers. The climb is gentle enough and the forest scenery your constant companion. Eventually the trail levels out and just past a small creek is a junction for the East Tiger Trail heading downhill to the northwest.
