Primitive camping sites and water are available at Flat Springs Gap and Balsam Gap. The trail is blazed with white paint on the trunks of trees. The first half mile north of Balsam Gap goes through a Fraser fir stand. No shelters exist on this trail. Extra care should be taken when hiking in the switchback section of the trail, as it is eroded by horseback use.
Parking is available at both ends of the trail.
Big Butt Trail starts at Cane River Gap and ascends in a southeastemly direction to the southern end of Wilson Ridge with switchbacks. This section has ramps in solid massing along the trail. The ramps start to get ripe in April and will run into May at higher elevations. Beware of the taste that may linger for days. The trail continues to climb to Flat Spring Knob and then descends to Flat Spring Gap.
