You can snowshoe anywhere in the park. The gentlest places are near the northwest entrance, while more challenging terrain is in the Southwest corner of the park but is easier to access because the park road stays open here all winter. Cross-country skiing is also popular in these areas.
Beware of hidden cavities in the snow. Park officials warn that heated sulfur emissions, especially in the Sulphur Works Area, can melt out dangerous snow caverns, which may be camouflaged by thin layers of fresh snow that skiers and snowshoers can easily fall through.
