The hike to Blue Lake is less than 4 miles on good trails with an elevation gain of about 2,200 ft.

The northern section of the Porcupine Ibex trail was opened for public use in late 2019. This 2.9-mile trail departs from the Porcupine Cabin and crosses the forested west slopes of the Crazy Mountains. The trail leads to a junction with the North Fork Elk Creek Trail #195 which heads to Campfire Lake and deep into the Crazies. The trailhead and parking area are right at the Porcupine Cabin which is a USFS rental unit.
