West Thumb Geyser Basin - 0.6mi Easy Boardwalk

Q: How long does it really take?

30-45 minutes if you move through steadily. 1-2 hours if you stop at every thermal feature and take photographs. The outer loop is longer; the inner loop takes 15 minutes.

Q: Can I do this if I'm out of shape?

Absolutely. This is a flat, paved boardwalk with no climbing, stairs, or elevation gain. Fitness is not a factor here.

Q: Do I need special hiking boots?

No. Regular shoes with good grip work fine. Avoid sandals or slippery-soled shoes—boardwalk surfaces are slippery when wet from thermal steam.

Q: Are there bears on this trail?

Bears are present in Yellowstone but rarely encounter crowds on this heavily-trafficked boardwalk. Make noise while walking; if you see a bear, back away slowly and give it 25+ yards of space.

Q: Is the thermal water drinkable?

Absolutely not. Thermal features are heavily mineralized and unsafe to drink. Carry your own water or fill up at the visitor center before starting.

Trail Highlights

Colorful thermal features and expansive Yellowstone Lake views from a safe, accessible boardwalk. The boardwalk passes through one of the park's most active geyser basins without technical climbing or exposure.

Insider Tips

• The outer loop at sunrise offers solitude and the best thermal colors before crowds arrive. • The inner loop is a 15-minute warm-up if time is tight. • Thermal geysers are most visibly active in cooler hours (dawn and dusk)—colors are vivid in low light. • Photograph from the northwestern boardwalk section for the best framing of thermal features against the lake. • Avoid the peak lunch hour (12-1 PM) if you dislike crowds.

Best Season to Hike

Summer and Fall (June-September)

Hiking Tips

Stay on the boardwalk—thermal features exceed boiling temperature and cause severe burns.
Bring at least 1L water even though it's short; thermal features and full sun exposure dehydrate faster than you expect.
Wear high-SPF sunscreen and a hat—reflection off the lake intensifies UV exposure.
Avoid peak hours (10am-3pm) by going at dawn or late afternoon.
Wear shoes with good grip; boardwalk surfaces are slippery when wet from thermal steam.
Tighten your boots before you go; the walk is easy but footing matters on damp surfaces.

Family Info

Excellent for families with young children. Thermal features attract kids but demand close supervision—thermal water causes severe burns. Keep children on the boardwalk at all times. The short distance and flat terrain make it ideal for toddlers and older adults. Stroller-friendly paved boardwalk.

What Hikers Say

Visitors consistently praise this trail for accessibility and thermal features without technical hiking. Families and time-crunched travelers find it rewarding. Most complaints center on crowding during peak hours, not the trail itself. Early-morning visits yield the best experience and solitude.
