Suitable for most fitness levels; riders should be able to mount/dismount a snowmobile and stand intermittently for balance.
Throttle up at Ten Mile Sno-Park and ride through volcanic landscapes—Paulina Lake, Paulina Falls, Big Obsidian Flow and, weather permitting, the summit of Paulina Peak—on a guided 4-hour snowmobile tour through Newberry National Volcanic Monument.
You push open the yurt flap at Ten Mile Sno-Park and the cold hits like a clean slate. Breath fogs, gloves clap on, and guides check helmets and goggles with the efficiency of people who read weather models for fun. Within minutes the engines cough to life and the sleds file onto trails that climb away from the pines, trading tree trunks for black glass: the jagged edge of the Big Obsidian Lava Flow ahead glints under a low winter sun.

Temperatures drop fast at higher elevations—wear a thermal base, insulated midlayer, and a windproof shell; carry liners or heated glove inserts for your hands.
Store phones and spare batteries inside an inner pocket to prevent cold-related shutdowns and bring a small dry bag for cameras.
Tours split by rider comfort—stay in your group to avoid rough terrain beyond your skill and to keep the tour on schedule.
Cold reduces thirst cues but dehydration and low energy are real—use an insulated bottle and pack calorie-dense snacks.
The Newberry area has been used seasonally by Indigenous peoples for millennia; the Big Obsidian Flow was used for toolmaking due to its sharp glassy rock.
Stay on designated trails to avoid disturbing fragile alpine vegetation and cultural sites; operators follow USFS guidelines to minimize impact.
