The trail here is nontechnical and climbs steadily along a stream up toward Bear Peak. This is a great trail to descend.

The ridgeline portion of Fern Canyon Trail offers excellent views of Boulder and the surrounding mountains, but the part of Fern Canyon Trail below treeline is not for the faint of heart. The trail is steep, rooty, rocky, and holds snow into the spring months.

The trail here gets rock and technical. The dappled from the shadows can obscure footing, so keep a sharp eye on the trail.

There is a charming stone bridge over Bear Creek that has small cascades flowing beneath it. Although power lines somewhat detract from its natural beauty, it is still a lovely spot to appreciate.

Bear Creek crosses the Mesa Trail between the Bear Canyon and Mallory Cave trails. If doing a longer hiking loop, this is a good spot to filter water so that you don't have to carry so much at the start. There are several other small streams that you will cross on the Mesa Trail, but some are seasonal and others are not strong enough to refill your bottle.

A big parking lot with restrooms and picnic tables. If this parking lot is full try the Meyers Gulch Trailhead instead โ it usually has available parking.

The stream runs through a narrow, rocky valley โ Rocky Mountain nature at its best. Right next to the river is a beatiful, well maintained trail.
