Mystic Falls Trail

A waterfall cascades over a cliff and flows into a stream down a rocky creek.

The 70-foot Mystic Falls is your objective on this 2.4-mile out-and-back through mixed conifer forest. Moderately strenuous with creek crossings; hydrothermal features nearby demand strict trail discipline. Most hikers complete it in 2-4 hours; the optional switchback loop adds 1.5 miles of elevation-gain punishment and an Upper Geyser Basin overlook.

Trailhead & access

Trailhead Location: Upper Geyser Basin, western Yellowstone. Primary access: far side of Biscuit Basin boardwalk (0.3 miles walk from parking). Alternate access: park in pullouts 0.25 miles south of Biscuit Basin, walk 0.5 miles north on Upper Geyser Basin–Biscuit Basin Trail to reach trailhead.
Parking Fill Time: Full by 8:30 AM in peak season (late June-August); moderate availability in shoulder seasons
Shuttle Required: 0
Shuttle Details: No shuttle required. Park at Biscuit Basin lot or in pullouts on either side of the road. Short walk to trailhead from either location.

Facilities & rules

Restrooms At Trailhead: 0
Water Sources: The trail follows a creek, but do not drink untreated water. Carry 2L from the trailhead.

Safety & strategy

Hazards: Hydrothermal water (boiling springs near trail)
Creek crossings
Uneven/rocky terrain
Crowds
Weather exposure at higher elevations
Hazard Details: The Upper Geyser Basin contains boiling springs and thermal features. Stay on the trail at all times—off-trail exploration can be fatal. Creek crossings are passable but slippery. Weather can shift rapidly; hypothermia is a real risk if you fall in and get wet.
Crowd Level: Conga line—this is the Upper Geyser Basin, the busiest section of Yellowstone
Peak Crowd Times: 8 AM-4 PM daily in summer; weekends July-August are maximum chaos
Best Season: Late spring through fall (May-October). Summer (June-August) is prime. Winter access possible but roads may be closed.
Best Time To Visit: Early morning (before 7 AM) to beat crowds and thermal steam. Summer and fall are prime; winter access depends on road conditions. Start by 6:30 AM if you want solitude in peak season.
Tips Advice: Carry 2L water minimum; creek is not reliably safe to drink untreated
Stay on maintained trail in hydrothermal areas—boiling water is close
Wear sturdy boots for uneven terrain and creek crossings
Start early; parking fills by 8:30 AM in peak season
Switchback loop adds serious elevation—only attempt if you're genuinely fit

More details

Park Area: Upper Geyser Basin
Trail Markers: Well-marked with cairns and maintained tread; easy to follow despite popular area wear
Dogs Allowed: No. Dogs are not permitted on trails in Yellowstone.
Biking Allowed: No. This is foot-traffic-only.
Shade Level: Partial shade from mixed conifer forest; open areas and full-sun exposure at overlook. Wear a hat.
Emergency Contacts: Park ranger stations and emergency radio at visitor areas. Mammoth District Ranger Station coordinates regional emergency response.
Map Recommended: 1
Snow Dates: Winter hiking via snowshoe possible after late-November closure, depending on conditions and permits
Mud Season: Late spring (May-early June) has muddy sections from snowmelt
Insider Tips: The false trailhead at the Biscuit Basin boardwalk overlook is not the real start—walk the full 0.3 miles to the far side
Most hikers turn around at the falls; the switchback loop is a serious lung-buster
Visit early morning to avoid thermal steam obscuring views and escaping the conga line
The creek crossing near the falls is slippery in summer—water shoes or extreme caution mandatory
Family Friendly Notes: The moderate difficulty and creek crossings challenge young children. Hand-holding mandatory near the falls and switchback overlook due to exposure. Older kids (10+) with hiking experience can manage it; make clear the thermal-hazard rules and enforce strictly.
Nearby Facilities: Biscuit Basin visitor area nearby. Midway Geyser Basin (6 miles south) has lodging and services.
Review Summary: Hikers consistently report the 70-foot falls deliver the promised payoff. Access is straightforward but hydrothermal hazards and creek exposure demand respect. Most fit hikers complete the base route in 2-3 hours.

Frequently asked questions

Are there bears in this area?

Yes. Make noise constantly—talk, clap, carry bear spray. This is active wildlife zone. Alone or small group, you're prey-sized. Never run.

How hard is the main trail really?

Steady climb, nothing technical. If you're breathless after a half-mile, slow down and hydrate. The switchback loop is where fitness matters.

Can I do this solo?

Yes. Tell someone your plan. Carry your phone (even if no signal) and bear spray. The trail is well-traveled. Thermal hazards are the real danger, not isolation.

Are the creek crossings dangerous?

Not if you're careful. Shallow and manageable, but slippery rocks in summer. Wear water shoes or cross carefully. One slip means a cold soak.

What if I'm not fit enough for the switchback loop?

Don't force it. The waterfall at 1.2 miles is the payoff. Retreat with dignity, hydrate, and come back when you're stronger. Pride dies on the descent; hypothermia kills.

Do I need trekking poles?

Smart move. The descent hammers your knees, especially if you do the full loop. Poles help with creek crossings too. Carry them.
