The Brim trailhead altitude is 8600 feet, with 300 feet of elevation loss on the downslope to the south end of the loop. The slopes on the singletrack are gradual enough that, despite the elevation, the ride is easy aerobically. The trail is well-built and is a great ride for all ability levels.

In 2021, the trailhead has ample parking and is well-marked. The trail is the singletrack between the big boulders on the west (downhill) side. Note that a second trail, about 50 feet to the right (north) is Baggage Claim. While it does link to Brim via a connector lower on the mountain, this trail is NOT Brim.
The return route -- or the outgoing track for a clockwise ride -- is the doubletrack at 90 degrees to your left, not the doubletrack straight ahead. First-timers should take the singletrack counterclockwise to avoid getting lost.

This is one of the most scenic trails in Utah. It's the perfect mix of alpine meadows, groves of aspen and fir, and distant views. Just one gorgeous epic spectacle of scenery after another. You may find yourself stopping so often, it will get annoying. Beautiful scenery, interfering with your bike ride.
For wildflower fans, I'd give the meadows of Powder Mountain a top ranking among Utah's bike trails, if you can catch it at the right time. In late June to early July, it's real eye candy. Lots of flower-filled meadows in front of distant mountains.

The trail is easily done by experienced beginner riders. The flow of the trail is smooth. Turns are generous in radius and well-bermed. The few bumpy spots are short enough that beginning riders can cruise on through. In fact, these areas of rock-slab armored trail will be a highlight for young riders.

About 80% of the trail is in open meadow with clay-like soil. Avoid riding here when the soil is damp. This trail is closed to horses, so you won't have to contend with the chatter of post-hole hoof prints. But there were a few petrified rut spots where early-season riders found the dirt not quite ready for their tires.

As a concession to more advanced riders, there are frequent A/B splits. An easy line flows through, while the alternative line lets you launch off a bump or bang over a series of rocks.
At mile 0.1 of the loop when riding counterclockwise, keep straight (uphill and to the left) as the connector trail from Paper Airplane joins the Brim Loop.

As you near the south end of the loop riding counterclockwise, you'll run into a trail fork in fir forest. Keep right for the longer loop. The left fork is shorter and steeper (although still fairly mellow by Wasatch Mountain standards), and a tad more techy with roots and rocks.

At the south end of the loop you'll enter an area of quartzite boulders. Many form slabs, which in a few spots have been laid horizontally to form a trail base.

As you head back northbound, you'll cross the biggest mules ear meadow you've ever seen. Then the trail contours along the slope on the east side of the ridge as it slowly climbs northbound.

You'll reach trail fork at mile 7.9 of the ride below. To the right is the Doctor's Dozen trail , which circles the mountain before descending to Hidden Lake. If you're only doing the Brim loop, keep left. When the trail ends 100 feet later on dirt road, keep straight (right) and northbound. This dirt road will take you back to the spot where you entered the singletrack. Just keep straight at all forks in the road.

Getting there:  From I-15, take Exit 347 to Ogden Canyon. Drive 7 miles up Highway 39 and turn left across the Pine View dam onto Highway 158. Four miles later as you pass the gas station in Eden, keep straight at the stop sign. Drive steep uphill 7 more miles to Powder Mountain. Pass the lower lifts on your left as you follow a turn in the road. The next road on your right is Powder Ridge. Turn and climb.
Brim Trailhead:  Drive 1.2 miles uphill on Powder Ridge Road. Keep straight and level as a road forks away to the right and another forks left uphill to Hidden Lake Lodge parking. Follow the road for one mile as it traverses a wide canyon and ends at the Brim Trailhead.

No water or bathroom at trailhead.
