This trailhead is located on the Glacial Boulder pullout on the road to Inspiration Point of the Grand Canyon of the Yellowstone. From this trailhead, you can access the following trails:

• Seven Mile Hole Trail
• Mount Washburn Spur Trail

Seven Mile Hole Trail

This strenuous 10-mile (16-km) there-and-back trail that begins and ends at the same trailhead. It traverses through trees near the canyon rim and with some views of Silver Cord Cascade across the canyon. It descends a steep 1,200 feet (365 m) to the Yellowstone river and the return is just as steep! CAUTION Grizzly bears frequent this area. Watch your footing and conserve your energy. Be especially careful where the trail passes both dormant and active hot springs. Stay on the trail. The only reliable water source on the trail is the Yellowstone River (filter water before drinking).

Mount Washburn Spur Trail

This 10.4-mile (16.7-km) there-and-back trail runs from the junction of the Seven Mile Hole Trail, past the Washburn Hot Springs, and on up to the top of Mount Washburn.

Be Prepared for a Bear Encounter

Grizzly and black bears inhabit all of Yellowstone National Park.

Make Noise: Avoid surprising a bear by calling out and clapping your hands at regular intervals to make your presence known.

Carry Bear Spray: Carry bear spray and know how to use it. Keep it immediately available, not inside your pack.

Hike in Groups: Travel in groups of 3 or more is recommended. Stay with your group at all times.

What to do...

If You Encounter a Bear: Stay calm, do not run. Quietly detour or back away; stop if this seems to agitate the bear. Stay at least 100 yards (91 m) from bears. Do NOT feed bears or other animals.

If a Bear Charges You: Stand still, do not run. Stand your ground and use your bear spray. Spray when the bear is 60 feet (18 m) away or closer. If a bear charges, it may be a bluff charge.

If a Bear Makes Contact: Drop to the ground; play dead. Lie face down and clasp your hands over the back of your neck; stay still and silent. Wait several minutes after the bear leaves before getting up and leaving the area.
