Beginning August 1st, people may apply to the 2020-2021 winter lottery for permits to snowmobile in Yellowstone without a commercial guide. Authorized in 2013, the Non-commercially Guided Snowmobile Access Program allows one group of up to five snowmobiles to enter Yellowstone from each of its four winter entrances per day. This year’s lottery will be open at recreation.gov from August 1st through the 31st. Successful applicants will be notified in early September. Unclaimed or cancelled permits will be made available at that site on a first-come, first-serve basis beginning on October 1st. There is no waiting list. Cancellations may occur throughout the winter season, so check the website often for openings. Trips can be for a maximum of three days in length, and permits cost $40 per day with a $6 application fee.
