Mid-December thru February (depending on snow conditions).
The 7 mile loop road will be groomed for skiing as snow pack allows and there are no entry or user fees. Most of the Winter Trail follows relatively level terrain and can be completed in 2-4 hours. There are also excellent opportunities for snowshoeing throughout the park including our 1.5 mile Snowshoe Loop Trail. Please note that pets are not permitted on any of our trails.
