Seven Mile Hole Trail

Route Description for Seven Mile Hole Trail

The Seven Mile Hole Trail is a challenging adventure in the Wyoming wilderness. This trail is difficult with a steep and loose descent that turns into a strenuous ascent on the way back out. Proper hiking footwear and lots of water is essential, and we strongly recommend bringing hiking poles on this trail to provide some support. As with any hike in Yellowstone, there is a chance that you will encounter bears. Before you set out on your hike, make sure that everyone in your hiking party is familiar with bear safety protocols. At least one member of your group should carry bear spray and know how to use it properly. If you do encounter wild animals on the trail, do not approach or feed them and be sure to admire them from a safe distance.

The Seven Mile Hole Trail is a fabulous hike through Yellowstone National Park. This trail has it all: cascading waterfalls, geothermal wonders, and spectacular views. The Seven Mile Hole Trail is totally worth the effort if you are up for a challenge.

Beginning at the Glacial Boulder Trailhead, follow the path past the impressive 500-ton rock. This boulder was dropped here by a receding glacier over 80 000 years ago. Approximately one mile past the boulder, look for the Silvercord Cascade, a 366 m ribbon waterfall on the right-hand side of the trail. Past the Silvercord Cascade, you will enter the Geothermal Area, a zone with several dormant and active hot springs. For your safety, do not venture off the trail in this area. Thermal features can be dangerous and deadly.

After venturing through the Geothermal Area, the trail will descend sharply down to the Yellowstone River. Check out the campgrounds along the river; the campgrounds are a great place to enjoy your lunch before heading back to the trailhead. Alternatively, you can find a good spot in the campground and set up your tent for a night along the bank of the Yellowstone River.
When you are ready to head home, simply retrace your steps back to the Glacial Boulder Trailhead, where you began.
