Features Birding · Geological Significance

This 9.1 mile out-and-back trail is a quiet and beautiful run located just outside Bryce National Park. This run takes you on ridgelines and through awe inspiring hoodoos similar to those of Bryce. The surrounding terrain is filled with ponderosa and bristlecone pines. These ancient trees live so long the ground tends to erode around the base of them. This makes the trees seem like they're clawing at the ground to hang on. Bring plenty of water and snacks as you are entering the backcountry where there tends to be fewer people. Horseback riders and mountain bikers use this trail, keep an eye out for them and be respectful.

Thunderstorms are common and can roll in quickly, especially in the summer months. Check the forecast, be observant, and make sure to get off the trail in the event of a thunderstorm.

This is runnable but has few steep sections, running it from top to bottom would be a great option if you have a someone to drive you to the top.

Park at the Thunder Mountain trailhead and start running south out of the parking lot on the well-marked path. Meander through ancient ponderosa pines, and juniper trees 1.4 where you intersect Grandview trail and Thunder Mountain. Here take a left onto Thunder Mountain Trail.

From this point follow the well defined trail through a few small washes before ascending a steep hill with many switchbacks. Once on top you'll find yourself running exposed ridgelines and through iconic hoodoos. The surrounding terrain makes you feel like you're on a different planet. Bristlecone pines cling steadfastly to eroding earth on the steep hillsides. These trees are ancient and can vary in age, but some live to be thousands of years old.

Continue on the trail until reaching a small outhouse and picnic area. This is a great place to turn around as it offers a good resting spot and some of the best running the trail has to offer. If feeling inspired, continue running the trail, another 3.5 miles to an obvious campground, with another pit toilet. This marks the end of the Thunder Mountain trailhead and a great place to turn around.

Along with the bristlecone pines, other magnificent conifers like ponderosa pines and large juniper trees thrive in this area.
