Ruby Loop
This is a 5.3-mile loop in Empire Canyon, starting just a little uphill from the Empire Canyon Lodge. The loop starts at 8300 feet elevation on the road to Guardsman Pass and climbs to 9000 feet at the top of the Ruby lift. You can reach the loop from other Park City and Deer Valley trails for a longer ride. Over half of this loop is brand new trail, just opened in September 2011. Most of the riding is in forest, with occasional breakouts with views over Park City. At the top, there are views south over the Heber Valley as well.

Getting there:
As you enter Park City, follow the signs for Deer Valley and Guardsman Road. Get on Bonanza Drive heading south uphill. At the roundabout, turn toward Empire Canyon (SR 224). Stay on that road for about 3.5 miles. Go through the roundabout in front of Empire Canyon Lodge and head uphill on 224. Just after the turn to the right, park on the left side of the road. The Midmountain Trail is back downhill just above the turn. Head left (west).
