Mystic Falls

Overview

Mystic Falls is the kind of Yellowstone payoff everyone loves: a quick, pretty hike that ends at a 70‑foot waterfall, with the option to push a little higher for a sweeping view across the Upper Geyser Basin. It starts through Biscuit Basin’s boardwalk of vivid hot springs and frequent‑erupting Jewel Geyser before the dirt trail follows the Little Firehole River to the falls.

The Hike

• Out‑and‑back: about 2.4 miles round‑trip with roughly 250 feet of gain to the base views of the falls—easy to moderate and great for most hikers.
• Loop option: extend to roughly 3.4–3.5 miles via steep switchbacks (about 500–600 feet of total gain) to an overlook, then return on the Fairy Creek Trail. It’s a short, punchy climb with big rewards. Times right, you can even spot Old Faithful erupting from up high.
• Expect occasional narrow tread and spots that can be muddy or slick after rain or early‑season melt.

Why It’s Special

You get a two‑for‑one: classic Yellowstone hydrothermal scenery on the approach, then a lively river canyon and waterfall. From the overlook, the panorama over the Upper Geyser Basin ties the whole area together—geysers, river, lodgepole forest—the works. Biscuit Basin itself has a cool backstory; historic eruptions reshaped features here, and Sapphire Pool’s once‑famous “biscuits” were blasted away decades ago.

Wildlife

This is bear country. Carry bear spray and know how to use it, make noise in brushy sections, and give all wildlife space (think 100 yards from bears/wolves, 25 yards from everything else). Early and late in the day are best for sightings. Mosquitoes can be feisty in late spring and early summer—repellent helps.

Logistics & Safety

• Start at Biscuit Basin: cross the bridge over the Firehole River and walk the boardwalk to the signed trail.
• No facilities at the trailhead—plan bathroom breaks and water fills in the Old Faithful area before you go.
• Stay on boardwalks and maintained trails in thermal areas; the ground can be thin and water scalding. Don’t soak in thermal outflows.
• Pets aren’t allowed on this trail.

Seasonal Notes

Mystic Falls is typically a fair‑weather favorite, but it’s also a beautiful snowshoe or cross‑country ski outing in winter when steam hangs over the river. Biscuit Basin experienced a hydrothermal explosion in 2024—check current conditions in case of any lingering closures that affect access.

Best Time to Visit

Aim for early morning or late afternoon for cooler temps, softer light, and fewer people. Shoulder seasons (just before Memorial Day or after Labor Day) are pleasantly quieter. Want the overlook moment? Grab eruption predictions at the Old Faithful area and time your loop accordingly.
