Upper Geyser Basin Trail

The Upper Geyser Basin Trail is composed of a network of paved paths and boardwalks that wind through Yellowstone’s Upper Geyser Basin. This is by far the best trail for viewing hydrothermal features in the park, hosting the highest concentration of geysers in the world.  Many of the park’s predictable geysers including Old Faithful, Castle, Grand, Daisy, and Riverside are also located here. The Upper Geyser Basin is a must-see for anyone traveling to Yellowstone! You can find information on when the next eruptions will occur by clicking here.

History of the Upper Geyser Basin Trail

This thermal area has been the most visited since the inception of European exploration in Yellowstone. Members of the Washburn Expedition of 1870 hold the first recorded visit to the Upper Geyser basin. They roosted around the area long enough to realize how regularly a certain geyser erupted and dubbed it Old Faithful.

Over 10 years later, the development of the trails and surrounding services began, the most historic piece being Old Faithful Inn. Construction began in 1903, after the only hotel in the area burned down. The designer of the Inn, Robert Reamer, used the area’s rhyolite for the foundation and Lodgepole pines for the walls. The result was a 6-story building that almost blended in with the temperate forest around it. 

The Upper Geyser Basin endured more and more development as world population and modern advancements grew. Through much of the 20th century, visitors practiced vandalism for fun, unaware of their impact. People would toss coins and all manner of trash into Morning Glory and other pools, diminishing their brilliant colors. Placing chairs on the mouth of Old Faithful and other cone geysers became common, so bystanders could watch such items get blown away upon eruption. The Old Faithful Historic District was added to the National Register of Historic Places in 1982. Today, the treasures it holds are much better protected and visitors are much more educated… for the most part.

3 Best Day Hikes on the Upper Geyser Basin Trail

A day hike around the Upper Geyser Basin is a wonderful way to see many diverse thermal features, including Old Faithful!

Below are the primary options for day hiking the Upper Geyser Basin Trail:

Destination Miles Elev Difficulty Style
Upper Geyser Basin Loop 3 mi +/-50 ft Easy Loop
Observation Point 1.5 mi +/-250 ft Easy Out and Back
Old Faithful to Biscuit Basin 5 mi +/- 100 ft Moderate Loop

1. Upper Geyser Basin Loop

You can’t visit Yellowstone without seeing Old Faithful at least once! Enjoy this classic geyser and the hundreds of other thermal features around her with the Upper Geyser Basin Loop. If you’re starting from the Visitor’s Center, we recommend checking the geyser times board above the Ranger’s desk. You can see the estimated eruption times for Old Faithful, Daisy, Castle, Riverside and more. Adjust your route accordingly, if any geysers are set to blow during your hike.

Start by turning left, heading Northwest along the 1.3-mile bike path to Morning Glory Pool. Don’t miss Castle Geyser half a mile down. The pockets in this enormous mound of geyserite really mimic the windows of an amorphous white castle. Continue straight until you reach Daisy geyser. If this cone is erupting soon, turn left to make the small loop around her. Continuing back along the main path, it’s only another quarter mile to Morning Glory, one of the most brilliantly colored hot springs in the world. Once you’re done admiring the blue, green, and yellow pool, turn back the way you came passing the frequently spitting Fan, Mortar, and Spiteful Geysers once more. If a Riverside geyser eruption is expected soon, take the short loop on your left.

Continue back the way you came a bit further, before turning left onto the wooden boardwalk next to Grotto Geyser. 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. Continuing along, you pass more fun features with thermal runoff producing wild colors and textures. 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. There is almost no elevation change along this route. Although this route is only 3 miles long, it can take about 2 hours to allot for time spent gawking at the unique geology.

2. Observation Point

Observation Point is a quick jaunt that allows you to admire Old Faithful Geyser without being elbow to elbow with hundreds of other people. If you’re starting from the Visitor’s Center, we recommend checking the estimated time of Old Faithful’s next eruption. You will likely enjoy a bird’s eye view of the display if you start about 30 minutes prior.

Head right along the boardwalk encircling Old Faithful. Then turn right at the Geyser Hill sign. After crossing the Firehole River via bridge, the sign and trail for Observation Point will be on your right. The paved path leads you through the forest, up about 200 feet in elevation to an open viewpoint along the hillside. Enjoy an aerial perspective of the Historic Old Faithful District, most of the steamy geyser basin, and Old Faithful herself. There will likely be other visitors, but not nearly as many as the boardwalks. If you’ve timed it well enough, this point is a great platform to watch Old Faithful erupt.

When you’re ready, return back the way you came. Observation Point is a 1.5 mile round trip hike from the Visitor’s Center. It also makes a great 1-mile addition to the typical Upper Geyser Basin Loop. Note: The path that once lead down to Solitary Geyser from Observation Point is closed temporarily due to changes in thermal activity causing unsafe terrain in 2018.

3. Old Faithful to Biscuit Basin

Connect the classic Old Faithful Geyser Basin Loop with its lesser known neighbor across the street, Biscuit Basin. Most people fight through 2-miles of traffic along Grand Loop Road and the chaos of 2 different parking lots to enjoy these basins separately. Thanks to your willingness to research, you can connect these trails with little extra mileage, saving yourself time and stress. Again, we recommend checking eruption times before leaving the Visitor’s Center 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.

From the Biscuit Basin parking lot, cross the bridge over the Firehole River. Keep an eye out for Cutthroat Trout in the clear shallow water. Follow the wooden boardwalk around the impossibly blue Sapphire Pool, the bubbled geyserite of Shell Geyser, the sunny tones of Mustard Spring and many more features. Once you’ve completed the lollipop shaped path through Biscuit Basin, return to the Upper Geyser Basin the way you came.

Once you’re back at Morning Glory, refer to our description of the classic loop to complete your route around the rest of the Upper Geyser Basin. This route is 5 miles with virtually no elevation change. It can be done in 3 to 5 hours depending on how much time you take to stop and gawk.

When to Hike and Seasonal Considerations

The Upper Geyser Basin trail can be hiked mid-April through early November, with the best months being August and September.  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 Upper Geyser Basin 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

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.

Necessary Permits

There are no permits required to do any day hiking in Yellowstone National Park. However, some areas can be closed to due high bear activity. Before you head out, you can check to see which Bear Management Areas are closed by clicking here.
