Yellowstone Snowmobile Tours

When is snowmobile season in Yellowstone?

Yellowstone's oversnow season runs from approximately mid-December through mid-March each winter. The exact opening and closing dates vary by a few days each year based on snow conditions and NPS scheduling. During this window, the park's interior roads are closed to wheeled vehicles and open only to commercially guided snowmobile groups and snowcoach tours operating under NPS-issued permits.

The season typically opens around December 15 and closes around March 15. January and February are the core months, with the most consistent snow coverage and coldest temperatures. Early December is a transition period when roads are being prepared, and late March may see trails deteriorating as temperatures rise.

Outside the oversnow season, you cannot snowmobile inside the park at all. The spring "shoulder" from mid-March through mid-April is a dead period when roads are closed to both wheeled and oversnow vehicles while the park plows and repairs. If you are planning a winter trip and want to combine snowmobiling with other activities, check our Yellowstone winter tours guide for the full picture of what runs during the cold months.

Do you need a guide to snowmobile in Yellowstone?

Yes, with one exception. The NPS requires all snowmobile travel inside Yellowstone to be commercially guided, meaning you ride with a licensed outfitter who holds a winter-use permit. The only exception is the unplowed road between Gardiner and Cooke City (the Northeast Entrance road), where limited non-commercially guided snowmobile access is sometimes available under a separate permit lottery. For all practical purposes, plan on joining a guided group.

This rule exists because of environmental and safety concerns. Yellowstone limits the total number of snowmobiles entering the park each day (historically around 318 to 540 transportation events per day, depending on the entrance). Every snowmobile must meet Best Available Technology (BAT) standards for emissions and noise. Commercial guides ensure these machines are used properly, riders stay on groomed routes, and wildlife encounters are handled safely.

Guided snowmobile tours typically run with groups of 6 to 12 riders. You follow the guide in a single-file line on groomed trails, stopping at designated pullouts for wildlife viewing and thermal features. The pace is moderate, averaging 25 to 35 mph. Most operators run full-day tours of 8 to 10 hours that cover 100 to 150 miles round trip, reaching Old Faithful, Canyon, or West Thumb from the West Yellowstone staging area.

How much do Yellowstone snowmobile tours cost?

A full-day guided snowmobile tour in Yellowstone costs between $275 and $450 per rider for a single machine, or $375 to $550 for a double (two riders sharing one snowmobile). Prices vary by operator, route, and whether you book on a weekday or weekend. Multi-day packages that include lodging in West Yellowstone typically run $600 to $1,200 per person for two to three days.

The price generally includes the snowmobile rental, all fuel, a guide, a park entry permit, and cold-weather riding gear (helmet, boots, snowsuit, gloves). Lunch is usually not included. Some operators offer a heated lunch stop at Old Faithful Snow Lodge, the only park lodging open in winter.

For multi-day Yellowstone winter itineraries that include snowmobiling as part of a broader trip, the 5-day hotel-based tour (around $2,995, check the live listing) and the 7-day Insight Vacations Discovery tour (around $6,012) operate during summer and shoulder seasons but illustrate the price range for multi-day guided Yellowstone experiences. Winter-specific multi-day packages from local outfitters in West Yellowstone occupy a similar mid-range tier.

Which snowmobile routes run inside the park?

There are four primary snowmobile routes inside Yellowstone, all originating from the West Entrance at West Yellowstone. The most popular route heads east through Madison Junction to Old Faithful (approximately 60 miles round trip). Other routes reach Canyon Village, West Thumb/Yellowstone Lake, and the Mammoth/Norris corridor. Each route follows groomed roads that are maintained daily by the NPS.

The Old Faithful route is the most commonly booked. You leave West Yellowstone at first light (around 7:30 to 8 a.m.), ride through the Madison River valley where bison herds often line the road, pass through Madison Junction, and follow the Firehole River south to Old Faithful. The round trip takes most of the day including stops at thermal features, a lunch break at Old Faithful Snow Lodge, and time watching the geyser erupt.

The Canyon route is longer and more strenuous, taking you through Norris Geyser Basin (the park's hottest and most changeable thermal area) and east to Canyon Village, where you can view the Grand Canyon of the Yellowstone and the frozen Lower Falls from the rim. This route covers roughly 100 miles round trip and suits experienced riders who want a more remote feel.

What gear do you need for a Yellowstone snowmobile tour?

Most guided tour operators provide the heavy gear: a one-piece snowsuit or bibs and jacket, insulated boots, a helmet with face shield, and heavy gloves or mittens. You should bring your own thermal base layers (top and bottom), warm socks, a balaclava or neck gaiter, and hand/toe warmers as backup. Temperatures during a ride commonly range from 0°F to 20°F, and wind chill on the machine pushes the felt temperature well below zero.

Even with the provided gear, comfort on a full-day ride depends on your base layers. Cotton is a poor choice because it holds moisture and loses insulation when damp. Merino wool or synthetic base layers are the standard recommendation. Bring an extra pair of dry socks and gloves in a daypack in case your first set gets wet.

A few other items to pack: a small daypack for personal items and snacks, sunglasses or goggles (snow glare is intense), sunscreen (the UV at Yellowstone's 7,000+ foot elevation reflects strongly off snow), and a camera with a battery you can keep warm inside your jacket. Phone batteries drain fast in extreme cold, so carry a power bank in an inside pocket.

One often-overlooked item: lip balm with SPF protection. The combination of wind, cold, and UV reflection off snow chaps lips rapidly. Apply before you put your helmet on, because stopping to dig through your pack mid-ride is inconvenient and your guide will not wait long. Similarly, apply sunscreen to any exposed skin around your eyes and nose before the ride starts. Reapplication at lunch break is wise if you are on a full-day trip.

Is snowmobiling in Yellowstone safe for beginners?

Yes, and the majority of riders on guided tours have little to no prior snowmobile experience. The machines used inside the park are four-stroke, BAT-compliant models that are quieter and easier to handle than older two-stroke sleds. Groomed trails are wide and well-maintained, and your guide sets a pace appropriate for the group's skill level. The primary risks are cold-related (frostbite, hypothermia) rather than mechanical, and those are managed by the gear and the guide's monitoring.

Before the ride, operators conduct a 15 to 30 minute orientation covering throttle and brake controls, hand signals, spacing, and what to do if you get stuck or need to stop. Riders must be at least 16 years old to operate a machine alone and have a valid driver's license. Passengers (who ride behind the driver) can be younger, depending on the operator's policy.

If you are traveling with children under 16 or prefer not to drive a machine yourself, a Yellowstone snowcoach tour is the better option. Snowcoaches carry 10 to 20 passengers in a heated, enclosed vehicle and cover similar routes. They are also warmer and more comfortable for full-day trips.

For summer visitors who want a guided multi-day experience with a similar adventure feel, the 4-day camping tour from Salt Lake City (around $1,050, check the live listing) covers hikes of 2 to 5 miles per day and accepts ages 7 and up. It is a good indicator of the kind of active-but-accessible trip the same operators run in different seasons.

How does snowmobiling compare to snowcoach tours?

Snowmobiles give you direct control over a machine and an open-air experience that feels immersive and physically engaging. Snowcoaches are enclosed, heated vehicles that carry groups of 10 to 20 people in comfort. Both reach the same destinations inside the park. The choice comes down to whether you want an active driving experience in the cold or a warm, relaxed ride with a naturalist narrating along the way.

There are practical differences beyond the experience itself. Snowmobiles are louder (even with BAT compliance), tire riders out more physically (steering, cold exposure), and require each adult rider to have a driver's license. Snowcoaches are quieter, carry more gear, allow for easier photography since your hands are free, and accommodate children and older travelers more comfortably.

Pricing is roughly comparable for a full-day trip, though snowmobiles cost more per person when ridden solo. A snowcoach seat runs around $250 to $350 per adult for a full-day Old Faithful trip, compared to $300 to $400 for a single snowmobile rider. The snowmobile double rider price ($375 to $500 for two people sharing one machine) brings the per-person cost closer to snowcoach levels.

Many visitors split their winter trip: one day on a snowmobile for the thrill, and one day on a snowcoach for the comfort and the guide's naturalist knowledge. If you only have one day, snowcoach is the safer bet for families and mixed-age groups, while snowmobiling suits couples and adventure-seekers who want to feel the park directly.

What wildlife will you see from a snowmobile in Yellowstone?

Bison are the most common wildlife encounter on every snowmobile route. Herds of 50 to 200 animals graze along the Madison River and Firehole River corridors, often standing directly on or beside the groomed trail. Wolf sightings are possible, especially in the Hayden Valley section of the Canyon route, and coyotes, elk, trumpeter swans, and bald eagles are regular sightings. Bears are denning during the snowmobile season (mid-December through mid-March), so you will not see them.

Your guide will stop the group when wildlife is spotted, and some of the most memorable moments on a snowmobile tour are the unplanned ones: a coyote pouncing on a vole in the snow 30 feet from the trail, or a bison bull exhaling clouds of steam as it plods past your parked machine. The cold, quiet landscape amplifies these encounters because there is no background noise from cars or crowds.

For visitors whose primary goal is wildlife observation, a dedicated wildlife-focused tour (summer, with binoculars and spotting scopes provided) is the better investment. But winter snowmobile tours deliver reliable bison and often wolf sightings as a bonus alongside the thermal-feature experience.

Where should you stay for a Yellowstone snowmobile trip?

West Yellowstone, Montana is the base for nearly all snowmobile tours entering from the park's West Entrance. It has the highest concentration of snowmobile outfitters, rental shops, hotels, and restaurants of any Yellowstone gateway in winter. Gardiner, Montana (north entrance) is the alternative for riders accessing the Mammoth to Norris corridor, and it has the advantage of being accessible by car year-round. Accommodation in both towns ranges from budget motels ($80 to $120/night in winter) to mid-range hotels ($150 to $250/night).

Inside the park, the only winter lodging is Old Faithful Snow Lodge and Mammoth Hot Springs Hotel. Both book up months in advance and are priced at $200 to $400 per night. Staying at Old Faithful Snow Lodge puts you inside the park, eliminating the need to ride in and out in a single day. You can explore the Upper Geyser Basin at dawn and dusk when thermal features are most dramatic against the cold air.

The town of West Yellowstone also serves as a staging area for your ride. Operators are clustered along Canyon Street and Yellowstone Avenue. You typically check in the evening before your ride for gear fitting, then meet at the shop early the next morning (around 7 a.m.) for the orientation and departure. Having your hotel within walking distance of the outfitter simplifies the early morning logistics.

If your Yellowstone trip spans multiple seasons or you want to combine winter snowmobiling with a summer guided tour of the park, note that West Yellowstone and Jackson are the two gateway towns with the broadest year-round outfitter infrastructure.
