The trail starts at the Fossil Ridge Trailhead and follows the Fossil Ridge Trail northwest. You will soon encounter an intersection, where you will keep left and continue climbing steadily through a dense forest of lodgepole pines. The trail is rocky and steep in places, so be prepared for some strenuous sections.
After about 3 miles, you will reach a junction with the Boulder Lake Trail, which branches off to the right. Follow this trail as it ascends more steeply through open meadows filled with wildflowers in the summer. You will also enjoy some spectacular views of the surrounding peaks and valleys as you hike.
The final stretch of the trail is the most challenging, as it traverses a rocky ridge with some exposure and loose gravel. Be careful and watch your footing as you make your way to the lake. You will be rewarded with a stunning sight of Boulder Lake, a clear and cold alpine lake surrounded by rugged mountains. You can relax by the shore, have a picnic, fish, or explore the area before retracing your steps back to the trailhead.
