The top of Sidewinder Trail splits off from AARP Trail, the bottom empties onto Big Ditch Trail. Sidewinder Trail is the most technical and difficult of the Greenhorn Park trails- there are some notable steep sections, several switchback and hairpin turns, the trail is build on the side of a steep slope, and there many rocks and roots to avoid.<br><br>The trail surface is mostly hardpack. This one can get muddy with rain, but not as bad as the lower trails in Greenhorn Park. <br><br>The trail is popular with hikers, dogs, other bikes, and runners, please stay in control and be careful. Have fun!
