Richards Hollow is a downhill trail in the Blacksmith Fork area near Logan, usually done after climbing dirt roads in a long loop ride. The Richards Hollow downhill segment itself has 5.6-mile/2000-vertical and 7.5-mile/2300-vertical options. As a loop ride, it's 15 miles with 9.3 on rocky gravel road, or 19 with 11.8 on-road.
The trail should clear by early June, but may still be a bit boggy in places with deep creek-crossings. Early July is probably ideal in terms of pretty flowers, enough water to play in, and not too much cow-damage. (The road closes November 15, and opens when conditions allow, usually June 1.)
The longer ride drops steeply to White Bedground Spring on doubletrack, then continues on singletrack along the creek. The singletrack here is narrow and much less-traveled, but it was buff and fun.
I found the uphill on the loop ride to be a very long and unexciting 10-mile commute. (But understand: I absolutely hate riding on crushed-rock roadway, and it was 95 degrees at the trailhead as I set out.) After the long grind uphill, Richards Hollow flew past way too quickly.
On the other hand, the road is rough enough that riding the trail as a DH with a shuttle vehicle could be tediously long. But maybe you're fortunate enough to have a volunteer to do all the driving...0.0 Parking area, bathroom. Alt=5500
