Mystic Falls

Mystic Falls Trail

General Description

The Mystic Falls trail leads you past the unique features of Biscuit Basin, through a peaceful forest path, and alongside the glimmering Little Firehole River. After just 1.5 miles you’ve reached the 70-foot cascade of Mystic Falls. The falls, river, and riparian foliage all create a picturesque scene. A heart pounding climb to the plateau above the falls gives you great views before looping back down to Biscuit Basin. This trail offers many dynamic rewards for such short mileage.

Getting to the Mystic Falls Trailhead

The Mystic Falls Trailhead is located behind the west side of the Biscuit Basin boardwalks. Park at the Biscuit Basin parking area, cross the Firehole River, and walk the boardwalks through the basin to access the trail. There are no restrooms or water at the trailhead. The nearest potable water is located at the Old Faithful Visitor Center. Click here for directions to the parking area.

History of the Mystic Falls Trail

Though the short trail to the waterfall bears little historical significance, geologists and historians have been keeping their eye on its trailhead since the Hayden Expedition of 1871. Biscuit Basin has always been a significant branch of the Upper Geyser Basin. One of its crown jewels, Sapphire Pool, was originally encrusted with connected pearls of siliceous sinter. These dollops reminded visitors of little biscuits, earning the basin its name. In 1959, the Hebgen Lake Earthquake caused a shift in thermal plumbing throughout the Western side of the park. The biggest change to Biscuit Basin was the placid Sapphire Pool’s transformation to a vivacious geyser. Every 2 hours, she would erupt to heights of 150 to 200 feet, sometimes lasting for 5 minutes. The violent bursts broke apart the iconic biscuits, sending most into the Firehole River never to be seen again. The pressure fueling Sapphire’s rage eventually waned, appearing to cease entirely in 1968. Today, she is simply a deep blue hot spring with no siliceous adornments or powerful eruptions.

3 Best Day Hikes on the Mystic Falls Trail

A short day hike on the Mystic Falls trail is a great way to experience how easy it is to leave the crowds behind.

Below are the primary options for day hiking the Mystic Falls Trail:

Destination Miles Elev Difficulty Style
Mystic Falls 3.5 mi +/-500 ft Easy Loop
Old Faithful to Mystic Falls 8 mi +/-550 ft Moderate Loop
Mystic + Precipitous Falls 10 mi +/-1400 ft Strenuous Out and Back

1. Mystic Falls

This is a short but rewarding loop that combines a well-known attraction with a lesser known gem. From the Biscuit Basin parking lot, you immediately cross the bridge over the Firehole River. The first features on your right will be the impossibly blue Sapphire pool and Jewel geyser with her pearl shaped sinter formations. On the other side of the boardwalk, runoff from Shell Geyser has created spongey orange terraces known as bacterial mats. The closer you look, the more bizarre these thermophilic colonies appear. You will pass a few more features before reaching a fork in the boardwalk. Turn left and continue on the dirt path into the forest. From here on, you will likely pass no more than a few hiking groups.

After .3 miles through this mixed conifer forest, you will reach a junction and turn left. Shortly thereafter, you will receive another option to head South along the Summit Lake trail. Stay right to continue toward Mystic Falls. Soon the trail will open up on your left side as you head upstream along the Little Firehole river. After 1 mile you will reach the beautiful 70-foot cascade of Mystic falls. Find a spot to roost and enjoy the rushing falls, sparkling river, and varnished rock walls. The riverside is adorned with wildflowers in August and fall foliage in September.

When you’re ready, continue along the trail as it makes steep switchbacks up the canyon wall. You will climb 500 feet in less than half a mile. At the top of the climb you will reach a junction with Fairy Creek trail. Turn right to head for the Biscuit Basin Overlook. This is an awesome viewpoint stretching to Old Faithful and beyond. From the overlook, you will descend a couple of switchbacks and then a straight gradual down climb to return to your first junction. Continue straight toward Biscuit Basin where we recommend completing the other side of the boardwalk loop. This hike will take most people 2-3 hours.

2. Old Faithful to Mystic Falls

This route combines 2 must-see geyser basins with the relief of a quiet hike to a water fall and aerial viewpoint in between. The loop will start and end at the Old Faithful Visitor’s Center. We recommend checking eruption times before leaving so you can adjust your route to catch any upcoming displays. Turning left from the Visitor’s Center, take the 1.3 mile bike path to Morning Glory Pool, stopping to admire whichever geysers excite you along the way. Use the compost toilet across from Morning Glory if you need it, as there are no restrooms at Biscuit Basin. Continue straight past Morning Glory, leaving the boardwalk and heading North along a forest trail. You will pass the lovely Artemisia, Gem, and Mirror pools with the Firehole River rushing in the background. After almost a mile, the trail will reach Grand Loop Road and you will see the parking lot of Biscuit Basin on the other side. Remember to look both ways before crossing, as drivers in Yellowstone are more focused on wildlife and scenery than watching out for pedestrians.

Upon reaching the Biscuit Basin parking lot, follow our description for the Mystic Falls hike. Once you complete the loop, return the way you came back to Morning Glory pool. Continue back along the main trail until you reach Grotto Geyser. Make a left at the wooden boardwalk here. It is about 1 mile from Grotto to the junction around Geyser Hill. You will pass a variety of otherworldly hot springs and geysers including Grand Geyser, a frequent performer. When you reach a fork along the boardwalk, turn right at the Lion geyser group. The other side of Geyser Hill will be closed temporarily due to unprecedented geyser activity in 2018 that has left the area unsafe for foot traffic. Closure signs are posted. When you reach the next fork in the boardwalk, turn right again to continue on safe terrain. Cross the Firehole River via bridge, head up the hill, and encircle Old Faithful to return to the Visitor’s Center. This hike can take 3-5 hours or more, depending on how much time you spend gawking at geysers.

3. Mystic + Precipitous Falls

This day hike allows you to enjoy the popular features of Biscuit Basin and Mystic Falls, with an adventurous backcountry excursion to a secret waterfall. When we say secret, we mean there is no established trail to this cascade and it’s not marked on any maps we’ve ever seen! Follow our Mystic Falls description until you’ve climbed up the canyon wall and reached the Fairy Creek Trail junction. Instead of heading right toward the Biscuit Basin Overlook, turn left to trudge into the backcountry. Until you return to this junction, you will probably have the trail all to yourself.

The path is flat and easy to follow. It is a thick new growth area with many wildflowers. Look out for the pink and yellow Pinedrops that grow at the base of the Lodgepole pines. After 3.3 miles you will climb down a few hundred feet to rejoin the Little Firehole River. You will have arrived at backcountry campsite OD3. You can’t miss the lovely 10-foot waterfall rushing right next to the site. To continue to a more secluded one, walk along the bank of the Little Firehole River heading East. After about 100 yards you will reach the 30-foot Precipitous Falls. Sit and soak up your time in the backcountry with this waterfall that few people know exists. When you’re ready, retrace your steps back to the junction with the Mystic Falls trail. We recommend continuing straight here so that you can enjoy the overlook before returning to Biscuit Basin. This exciting day will take most people 5-7 hours.

When to Hike and Seasonal Considerations

The Mystic Falls trail can be hiked mid-April through early November, with the best months being August and September. Depending on the amount of snowfall over the winter, snow can remain on the trail until June. Snowshoes might be helpful when hiking in the spring time. The months of June and July are mosquito season in Yellowstone. If you plan on hiking during these months remember to pack insect repellent!

The Mystic Falls trail is also great for cross-country skiing and snowshoeing in the winter time. If you are interested in hiking in the mountains during extreme winter conditions, make sure to educate yourself on how to travel in avalanche terrain. A good resource for this is “Know Before You Go”.

Traveling Around Geyser Basins

Thermal features, though fascinating, can easily scald or kill people who underestimate them. Even what appears to be solid ground in a thermal basin can give way to scalding water below. Backcountry basins require visitors to be even more educated as there are no boardwalks and safety boundaries are not as clearly defined. Thermal environments and the precious microorganisms that inhabit them are also extremely sensitive. Both biology and geology can be irreparably damaged by human contact. Follow these guidelines around thermal basins of any kind.

  • Always stay on boardwalks and designated trails
  • Do not touch thermal features
  • Do not touch or step on thermal runoff
  • Swimming or soaking in hot springs is prohibited and likely fatal
  • Pets are not allowed in thermal areas
  • Do not throw objects in features
  • Toxic gases can build to great intensity in some areas. If you feel sick, leave immediately. 

Animal Safety 

Wildlife is one of the best reasons to visit Yellowstone. With the privilege of hiking through their habitat comes great responsibility to uphold respect and safety. Becoming accustomed to humans is not good for the well-being of any wild animal. Even our docile herbivores can maim or kill people. The key to these guidelines is to just let the animals be.

  • Never feed wildlife (Not even a squirrel)
  • Do not approach wildlife
  • Stay at least 100 yards away from bears and wolves
  • Stay at least 25 yards away from all other animals
  • Do not shout, whistle, or otherwise harass wildlife

If you want to view wildlife from the road, always stop in a designated pull out.

Bear Safety

Yellowstone is black and grizzly bear country. Special practices are necessary to improve the safety of yourself, other visitors, and the animals. Most of these tactics aim to avoid making a bear react defensively. A bear will feel threatened if we surprise it, approach its cubs, or encroach on its food source. We must also do everything in our power to prevent a bear from eating human food or smelling an attractant where we sleep.

While Hiking

All of the following practices are necessary whether you are hiking in bear country for 5 minutes or 5 days.

  • Don’t hike alone (At least 3 people is best)
  • Always be alert
  • Make noise
  • Carry bear spray and know how to use it
  • Never feed a bear
  • Do not leave packs or any food unattended
  • Stay on maintained trails
  • Avoid carcasses
  • Avoid hiking at dawn, dusk, or night
  • Stay out of areas closed for bear management

While Camping

All of the following practices are necessary if you are sleeping outside in bear country.

  • Sleep away from where you cook and eat (100 yds in backcountry)
  • Do not sleep in clothing that smells like food
  • Keep all sleeping gear away from food odors
  • Strain your dishwater, putting particles in trash
  • Keep camp clean and free of trash
  • Store all attractants in a bear proof container or hang from food pole. (This includes: food, garbage, toiletries, stoves and fuel bottles, utensils, food containers, and anything scented)

Bear Encounters

As the park service says, safety cannot be guaranteed in these wild places. These are best practices to lower the risks of an aggressive bear encounter.

  • Do not run
  • Slowly back away (taking any food with you)
  • Speak calmly, do not shout
  • Group together, make yourselves look large
  • When necessary, use bear spray
  • Report conflicts to park rangers

Check out Yellowstone National Park’s great reference on how and when to use bear spray.
