Above the Geysers: Bunsen Peak Day Hike Through Yellowstone’s Northern Range
A knowledgeable guide and a steep pull reward you with Yellowstone panoramas, geology lessons, and wildlife watches.
At first light the trail smells like cold pine and dust; the air is thin with steam that the park’s thermal features breathe out all night. You step off the service road near Mammoth Hot Springs and the world tilts—open meadows give way to a steady climb where lodgepole pines thin and the northern range stretches: ridgelines of basalt and volcanic ash, the distant plumes of geysers and fumaroles like a reminder that Yellowstone still thinks in heat.
Trail Wisdom
Start Early
Begin at first light to avoid afternoon thunderstorms and secure calmer wildlife viewing on the valley floor.
Hydrate and Snack Often
Carry 2–3 liters and eat small snacks to sustain energy during the steady climb and at altitude.
Layer for Wind
Expect strong winds at the ridge—pack a light wind shell and insulating mid-layer.
Respect Wildlife Distance
Keep at least 100 yards from bears and wolves and 25 yards from other large animals; let your guide manage any close encounters.
Local Knowledge
Hidden Gems
- •The Lamar Valley pullouts for dawn wildlife watching (especially wolves and pronghorn)
- •The terraces at historic Mammoth Hot Springs—less crowded early morning or late afternoon
Wildlife
Elk, Bison
Conservation Note
Yellowstone manages sensitive thermal and wildlife zones—stay on trails, pack out waste, and follow your guide to minimize disturbance to fragile habitats.
Bunsen Peak was named for German chemist Robert Bunsen in the 19th century, reflecting the scientific interests of early park surveyors.
Seasonal Guide
spring
Best for: Wildflowers, Fewer crowds
Challenges: Late snow patches, Mud on lower trails
Spring offers emerging green and quieter trails but expect residual snow and muddy sections—microspikes may be needed early in the season.
summer
Best for: Clear summit views, Full guide services
Challenges: Thunderstorms, High daytime sun exposure
Summer is peak season for access and interpretive programming—start early to beat thunderstorm buildups and strong midday sun.
fall
Best for: Crisp air and color, Fewer visitors
Challenges: Colder temperatures, Shorter daylight hours
Autumn brings cooler air and clearer light; layers and an early start are crucial as days shorten quickly.
winter
Best for: Snowshoeing variants, Quiet solitude
Challenges: Deep snow, Limited services
Traditional summer routing is generally closed; winter access requires specialized gear and experience—check with guides for snow-specific trips.
Photographer's Notes
What to Bring
Sturdy Hiking BootsEssential
Provide traction and ankle support on steep, rocky switchbacks.
Wind Shell / Insulating LayerEssential
Blocks wind at the exposed summit and provides warmth during cold snaps.
Hydration Reservoir (2–3L)Essential
Allows easy sipping on the climb—important in dry, high-elevation air.
Trekking Poles
Reduce knee strain and steady balance on loose or steep sections.
Common Questions
How long is the hike and how much climbing is involved?
Guided days run 5–7 hours with roughly 5 miles round-trip and an elevation gain of about 1,800–2,200 feet, depending on exact routing and stops.
Do I need a permit to hike Bunsen Peak?
No special permits beyond park admission are required for a day hike; guided trips include necessary permits and park access details.
Is this hike suitable for children or inexperienced hikers?
Older children with hiking experience and stamina can manage; inexperienced hikers should prepare with shorter uphill hikes beforehand or opt for a guided pace with breaks.
What wildlife might I see on the trail?
Expect elk, bison in the valleys, and possibly mule deer; bears and wolves are possible—your guide will brief you on safety and distance rules.
What happens if the weather turns during the trip?
Guides monitor conditions closely and will adjust the itinerary—turnarounds are common for lightning risk or unmanageable weather.
Is transportation provided from nearby towns?
Wildland Trekking’s tour confirmation outlines meeting points; many groups gather at Mammoth or nearby park roads—confirm pickup and meeting details when you book.
What to Pack
Sturdy boots (support on rocky slopes), 2–3L hydration (dry air dehydrates), wind shell (ridge exposure), snacks/high-energy lunch (sustains during steady climb)
Did You Know
Bunsen Peak is named after German chemist Robert Bunsen—the same scientist associated with the Bunsen burner—recognized by 19th-century surveyors mapping Yellowstone.
Quick Travel Tips
Book early-morning departures, park at Mammoth Hot Springs for northern access, carry bear spray and know how to use it, expect limited cell coverage on the ridgeline
Local Flavor
After the hike, head to Gardiner for a beer at a local brewery or the Mammoth Hot Springs Hotel Dining Room for elk or trout; stop by the Albright Visitor Center to add historical depth to your field observations.
Logistics Snapshot
Closest airport: Bozeman Yellowstone Intl (BZN) ~1.5–2 hours drive; Trailhead: Mammoth Hot Springs area (park road access); Driving from Gardiner: ~20–30 minutes; Cell service: limited—expect gaps on the ridge; Permits/passes: Yellowstone park entrance fee required; guided trip handles permits.
Sustainability Note
This trail traverses sensitive elk and thermal habitats—stay on designated trails, pack out all waste, and avoid disturbing wildlife to help protect Yellowstone’s ecosystems.
