Trail Overview

The Pine Union Hill FSR 2137 is the first portion of the Pine Union in Mark Twain National Forest before it spilts to the 2137A and the Hilltop portion of the 2137. It begins at the Bo-Co Road 872 in the bottoms of the Grounds Creek, leading you past the Sycamore Valley Artisan Well where the Pine Union trail begins, it quickly climbs a mostly dirt trail with natural rock inter laced throughout. The hill includes ruts roughly 18" deep and off camber mounds of dirt. This trails difficulty is amplified by heavy rains and wet conditions.

Difficulty

The hill is a climb and takes some wise choices from the driver, the ruts are deep and the off camber spots make the suspension work to keep your tires traction. The hill can become extremely muddy and wet amplifying the difficulty.

Not sure the last time this was rated but the ruts are 24”+ in spots going up the climb now. Off camber and loose moderate grade climb.
