Seven Mile Hole Trail
What to Expect
Safety Advisory
Active thermal features border the trail during the descent — the ground near hot springs is dangerously thin and scalding water sits just below the surface. Stay on the established path even when it seems unnecessarily narrow.
The climb back out gains over a thousand feet with almost no shade. Heat exhaustion is a real risk on summer afternoons. If you're feeling dizzy or your skin stops sweating, stop immediately, find shade, and hydrate.
Loose volcanic rock on the switchbacks makes footing treacherous, especially on the descent. Trekking poles are not optional here — they're the difference between a controlled hike and a sketchy scramble.

Pro Tips
Start by 7 AM from the Glacial Boulder trailhead near Inspiration Point — you want to make the steep return climb before the afternoon sun turns the exposed switchbacks into a convection oven.
Carry at least three liters of water per person. The only water source at the bottom is the Yellowstone River, which needs filtering and is not always easily accessible depending on seasonal flow. There is nothing drinkable on the climb back out.
The best photography of Silver Cord Cascade happens within the first mile, around mid-morning when the sun lights up the opposite canyon wall. Don't rush past it thinking the bottom is the only prize — many hikers say the rim views outshine the destination.
