Description: Rolling Hills Park (RHP) is part of the Washtenaw County Parks system. The park includes several miles of hiking/ski trails, paved walking paths, a disc golf course and a water park. The single track mountain bike trail was built by Potawatomi Chapter volunteers. Phase 1 of the RHP trail which was completed in November 2009 measures out at 3.0 miles long. The trail was designed to take maximum advantage of the “rolling hills” left behind from glacial deposits. The terrain continually ungulates and the trail twists and meanders to follow it. The trail is technical, but not difficult while forcing the rider to pay attention to the terrain ahead and constantly maneuver the bike around the next obstacle or turn. In several locations, there are log piles or more technical riding challenges, most of which have easier ‘ride arounds’. Notable features include the S-bend at ~0.3 miles, the Crater at ~1 mile, the Bluff at ~1.5 miles and a very large log pile at ~2.5 miles. The RHP single track can be easily combined with the nearby Hewens Creek MTB trail (~2 miles on Bemis Road) for a combined ride of ~11 miles.

The current Phase 1 trail layout temporarily connects the western edge of the park to the finish section by ~300 yards of the park walking paths. In late 2010 and early 2011, both the park and the MTB trail will expand significantly to the north and northwest, connecting the current trail on the park’s west edge to 2-3 miles of additional trail. The MTB expansion is also planned to include a ‘skills park’ in and around the old gravel pit to the northwest and some higher speed sections in the flatter terrain to the north. At some point in the not too distant future, it is hoped there will be a connector trail from RHP to Hewens Creek.
