Suitable for most fitness levels; riders should be able to mount/dismount a snowmobile and tolerate short periods standing or bracing on uneven footing.
Throttle up and cross a frozen caldera: this two-hour guided snowmobile tour through Newberry National Volcanic Monument delivers obsidian fields, icy waterfalls, and summit views when conditions allow. Practical directions and local geology make it ideal for first-time riders and experienced drivers alike.
A cold breath of wind meets the first engine cough, and the snowfield ahead seems to inhale in response. On a two-hour guided snowmobile tour of Newberry National Volcanic Monument, riders trade the hum of everyday life for the steady thrum of machines and the hush of high-country winter. The route threads across pumice flats and old lava, curves past Paulina Lake’s glassy edge and pauses where Paulina Falls thunders into a frosted slot. If weather allows, guides push toward Paulina Peak, and the caldera opens beneath you—an enormous bowl of frozen lakes and volcanic canvas.

Plan to arrive 60 minutes before departure to fit helmets, review safety briefings, and complete paperwork—arrivals within 20 minutes of the start may be cancelled.
Wear insulated base and mid-layers plus a windproof outer shell; temperatures on Paulina Peak can feel much colder than at trailhead.
Use a wrist or chest strap for cameras and phones—the glare is brutal and dropping gear on obsidian or ice is easy.
Stay with the group and obey route instructions; guides alter courses for safety and to protect fragile volcanic features.
Newberry Volcano’s caldera formed through repeated eruptions over tens of thousands of years; the area was designated a National Volcanic Monument in 1990 to protect its geological features.
Operators follow Forest Service permits and keep groups on established trails to reduce impacts; riders should avoid riding on fragile obsidian and vegetation.
Blocks wind and traps heat during exposed high-elevation stretches.
