This hike starts at the north end of Swan Lake Flat and goes through a forest and then down the mountain into a large field of tumbled travertine rock. At the north end of Swan Lake Flat, hike until you reach the sign that says Fawn Pass, and head right to the north. You'll hike through lodgepole pine and Engelmann spruce and then you'll see a couple great views--one of Swan Lake Flat and the surrounding mountains, and then after that, of the area to the north. Hike down the mountain carefully through the Hoodoos. At the end of them, turn around and come back.
This is a great “triangle loop” trail across a prairie field, over a mountain pass, then along a portion of the Howard Eaton Trail through the fascinating Hoodoos. From Glen Creek trailhead, first segment along Fawn Pass Trail features terrific mountain scenery. Bear right at first trail junction to head up to Snow Pass (not terribly steep), then down (long, steep descent). You DO NOT want to attempt this route counterclockwise – this long, steady climb would be a killer! At junction with Howard Eaton Trail, turn right to head through a section featuring lovely mountain scenery, with Bunsen Peak looming ahead. Hiking through the Hoodoos is a truly unique experience, walking among the jumble of huge boulders from the nearby cliff. After leaving the Hoodoos, trail narrows and climbs gradually along mountainside until topping out near Golden Gate. (Highway is visible below through much of this segment.) From the windy highpoint, trail winds leisurely through pretty forest back to junction near highway. This was a thoroughly enjoyable hike with lots of variety! Carry (and drink) plenty of water, make lots of noise (“Hey, bear – comin’ through!”) and ALWAYS carry bear spray.
This is a really great hike. There's only one really steep part that needs to have careful attention when walking. In the Hoodoos, there are pika. If you stay for a few minutes and stay quite, they'll come out of their little holes and start making noises and eating. I consider this hike to be 4 miles.
OK I'm giving another secret away. Look for the Hoodoos turnout on the West side of the road, the turnout is a small road that goes behind the rocks so look closely for it. If you grab a flashlight and start rock climbing onto the hill to the West of the turnout you will start finding holes in the rocks, everywhere! Climb into them and you will find connecting rooms and paths all through the rocks making this place a blast for kids and the young at heart to explore. You will be surprised at the size of this place, it is similiar but larger then the Indian Caves in Yosemite Valley.
