Description

The trail departs from New Fork Lakes and ascends through New Fork Park. It then crosses Porcupine Pass and follows Porcupine Creek to T into the Highline Trail / CDT: Summit Lake to Union Pass (WY Sec. 15) between Upper Green River Lake and Lower Green River Lake. The full trail is long, and the terrain is tough, with much elevation gain along the way. However, if broken into smaller sections, the route can be a pleasant way to explore the area.

Be sure to either arrange a shuttle back to your starting point or be prepared to make the return journey on foot.

Last light of the evening on the cliffs, as the sun drops below the mountains.  Here, the New Fork River runs through the meadows and brush of New Fork Park, a good place to camp.
