“A rocky, wooded single/doubletrack on the bottom section and a long steep fire road at the top.
— Craig Gleason
From the dam at Lexington Reservoir, take Alma Bridge Road around the east side of the reservoir. The Limekiln Trailhead is just after the first hairpin. The trail begins with a climb on broken pavement and then turns to single and doubletrack, eventually descending into the woods. After the descent, the real climb begins. This lower section of Limekiln is known as Overgrown. It follows a pattern of bending to the right and increasing grade, then back to the left and moderating. There are several challenging, loose, and rocky pitches on this part.
At the top of Overgrown, the trail emerges from the woods and crosses the Priest Rock Trail
. From this point there are two climbing options, up the very steep and loose "Dogmeat" section of Priest Rock or continuing on the Limekiln Trail. There are two options to descend, either back down Overgrown (loose and rocky) or down the Priest Rock fire road (steep but a bit boring).
Continuing on, Limekiln becomes a fire road and begins to descend at this point, and then begins a long, steep climb to the junction with Kennedy Road. This part of the trail is known as Power Poles. From the top there are three ways to descend: Back on Limekiln, down the Kennedy Trail
, or over the top of El Sombroso to Woods Road.
