Looping Among the World’s Geysers: A 6-Mile Hike Through Yellowstone’s Upper Geyser Basin
Walk the loop that turns Old Faithful from a single moment into a full-day story of geysers, wildlife, and thermal wonder
You step onto the boardwalk before the sun has finished waking the basin, steam rising like a low, slow tide. The smell is sulfurous but not unpleasant, mineral and ancient, and the trail ahead alternates between wide wooden planks and narrow dirt that threads through sagebrush and lodgepole pine. By the time you pass the last cluster of colorful pools, Old Faithful appears not as a postcard icon but as a mid-hike punctuation mark: you’ve earned a front-row look where steam and schedule intersect.
Trail Wisdom
Respect the boardwalk
Stay on marked boardwalks and trails at all times — thermal ground is fragile and dangerous.
Carry bear spray
Bring accessible bear spray and know how to use it; wildlife encounters are possible on quieter stretches.
Layer for altitude
Temperatures shift rapidly at 7,300 ft; wear moisture-wicking base layers and a windproof shell.
Hydrate and snack
Bring at least 2 liters of water and light snacks even if lunch is provided, especially on warm days.

Seasonal Guide
spring
Best for: Fewer crowds, Wildflower emergence
Challenges: Unpredictable weather, Snow patches on trails
Late spring opens quieter trails and active runoff, but expect snow or muddy sections early in the season.
summer
Best for: Warm hiking conditions, Full trail access
Challenges: High visitor numbers, Limited parking
Summer brings reliable trail access and long daylight but also large crowds around Old Faithful; mornings are best.
fall
Best for: Cooler air and light crowds, Autumn colors in the meadows
Challenges: Shorter days, Potential early snowfall
Early fall offers crisp air and thinning crowds — ideal for photos and calmer wildlife viewing.
winter
Best for: Snowy landscapes, Unique thermal contrasts
Challenges: Most roads closed, Requires specialized transport
Winter access is limited and often requires snowcoach or guided snowmobile trips; expect subfreezing temps.

Common Questions
How long is the hike and how strenuous is it?
The loop is about 6 miles and typically takes 4–6 hours; terrain is mostly moderate with some uneven dirt sections and boardwalks — suitable for fit beginners and regular hikers.
Is the hike safe for kids?
Older children who can comfortably hike several miles are fine, but keep them close on boardwalks and near thermal features; small kids may struggle with the distance.
Are pets allowed on this tour?
Yellowstone does not allow pets on most trails and boardwalks; pets are generally not permitted on guided hikes inside the park.
Do I need a park pass or permit?
Yes — a Yellowstone National Park entrance fee is required; no special permits are needed for this guided day hike beyond the tour booking.
What wildlife might I see?
Common sightings include bison and elk; bears and wolves are possible but less frequent — guides follow strict wildlife protocols to maximize safety.
What should I do if I encounter bison or bear on trail?
Give wildlife plenty of space, move off the trail if possible, follow guide instructions, and never approach or feed animals; carry bear spray and know how to use it.
What to Pack
Sturdy boots for uneven terrain, layered jacket for shifting weather, 2 liters of water for hydration, bear spray for wildlife safety
