Pleasant out n back bike ride on the mostly gravel/dirt surface of an old railroad bed. The trail follows an old railroad grade 25 miles from Park City to Echo Utah. If ridden from south to north it is an easy flat to downhill ride. The northern section from Coalville to Echo is somewhat overgrown with lots of puncture causing stickers.For those who want more adventure, make this a 64 mile loop by continuing north at Echo Reservoir to Henefer, west to East Canyon Resort, south on Jeremy Ranch Rd to Summit and then back to PC.
