Don't let the "Mud Flats" name fool you. This is a nice ride with a shady singletrack climb up the canyon along Willow Creek. There's a fast ride along a dirt-road connector, then a singletrack descent down Little Cottonwood Creek to the trailhead. The loop starts at an altitude of 5500 feet, climbing to 6850. Total climbing will be around 1400 feet.

The trail starts in the right fork of Logan Canyon. Go 0.7 miles up the paved road, then veer left just past the campground and enter a gravel road.

At the far end of a turn-around, about 1/2 mile from the fork, is the singletrack. There's a bathroom in the middle of the turn-around.

The trail maintains a steady rate of climb. At first it's a middle chainring sort of thing, but as you near the top, you may want to slip into granny. The trail is mostly shaded with aspen and occasional fir or pine. There are several bridges over the creek, or you can follow the "horse route" and plunge right through.

Your first fork is at Ricks Hollow at mile 0.6. Head left along Willow Creek.

Next, keep left as you pass Ephraims Cutoff at mile 2.5. This trail is a 3.5-mile long connector to the road at Long Hollow.

From what I hear, this trail is a reasonable route back from Old Ephraims Grave, but it's too steep to climb. (If you want to pay Ephraim your respects, continue up Willow Creek then turn RIGHT toward Long Hollow when you get to the top.)

At 3.5 miles the Willow Creek singletrack reaches the dirt Temple Fork - Long Hollow road. Go left, then left when you reach a smaller dirt road near the top of the hill.

You're not through climbing yet. Once you're on the smaller dirt road, you'll climb, then descend a total of 3.5 miles. Keep left at two intersections. Then the road turns 90 degrees left at a fence.

Descend to a water trough, where the road ends. Follow one of the cow-path tracks downhill until you hit true singletrack as you enter the trees along the creek.

You've now got one mile of nice singletrack downhill. You'll hit bottom behind the corral you passed just before the parking area. Go left behind the corral and head for your car.

Getting there:
From Logan's main street, turn east towards the mountains on US-89 (4th North). Pass Utah State University and enter Logan Canyon. 8.5 miles from the canyon mouth, turn right to Right Fork Logan Canyon. 0.7 miles later, fork L and the road becomes gravel. 0.6 miles further, just past a large corral, that road loops around a bathroom. The trailhead is at the end of the loop. N41 46.508 W111 36.637.
