Porcupine Gulch is a 7 mile lightly trafficked out and back trail located near Dillon, CO that features a river and is rated as difficult. The trail is primarily used for hiking and downhill skiing and is accessible from June until October.
An infrequently used trail from US Hwy 6 to the ridge overlooking I-70 just West of the Eisenhower Tunnel. Beginning with an old jeep track, this long neglected trail has numerous deadfall obstacles, stream crossings and challenging route finding (and ascent) as the valley forks near the 1.5 mile mark. Solitude, a cascading stream and expansive views from the ridge.
Really nice trail. Stays fairly close to fast running streams which you cross and under the trees making for a cool hike in the summer. Nice variety of terrain. Steep at first but mostly a mild elevation gain.
I like the solitude of this hike. The forest is also very healthy, unusual for this area with the pine beetle infestation throughout summit county. This looks like it may be a good ski tour when the snow flies although parking may be an issue.
