Great hiking.
Approximately 35 miles east of Salt Lake City. Hailstone (main boat ramp) - Take I-80 east to US 40 south, then take the Mayflower exit (#8); Rock Cliff (nature center) - Take I-80 east to US 40 south, at the traffic light turn left to U 32 east, travel about 7.5 miles then left on Rock Cliff Road.
