See the snow ghosts of Two Top on the most famous trail in all of North America! Two Top Trail is a popular choice for its variety of terrain and 2,000-foot elevation gain. The trail is groomed, and powder fields abound. This trail has everything and makes it one of the most visited trails in the system. Whether you are a novice or an expert, you will enjoy this well-groomed trail. This trail is a large loop with plenty of extra off-trail riding for those in search of more adventure. There are numerous bowls out there with drop-offs and overhanging cliffs. The bowls are great to ride, but make sure you know where you are out there.

On clear days you can view the Teton Mountains and be treated to an incredible panorama of the entire region. From the upper areas, the surrounding mountain ranges come into view, including Wyoming's Teton's, Idaho's Centennial Mountains, Lionhead in Montana, and Yellowstone National Park. Constant-driven winds create ghostly ice patterns plastered on the trees at the top of this mountain creating the famous "snow ghosts."

Two top mountain

Absolutely a must do trail experience. Beautiful scenery along the way. We saw two baby moose and their momma grazing in the water. During summer this is the premier ATV trail. Winter time take your snowmobile. Be sure to stop at Earnie's before your trip to buy your"brown bag" lunch. They give you everything you need to last all day on the trail. There are plenty of places to stop and get fresh water along the way. When you reach the top of Two Top Mountain it is breathtaking. A perfect place to have lunch or a snack. Don't forget to make this trip at night, too. The lights twinkling in downtown West Yellowstone is an experience in itself. Go on a moonless night and see the milky way in all its glory. Two top mountain trail is an experience you will always remember.
