We are continuing to offer the same after-hours uphill/downhill access on Dollar Mountain that has existed in years past. Uphill hiking is permitted outside of normal lift operating hours (typically from 4:15pm to 9am, weather and conditions permitting). There are no designated routes for after-hours access however the terrain must’ve been open the day prior (check the mountain report) and terrain parks are closed outside of operating hours. Access is permitted from Dollar Base and Elkhorn. Dogs are permitted on the mountain. We ask that guests please be considerate of others and clean up after their furry friends.
