The distance from the parking area to the old resort is just over 8km. Then you get to start hiking the runs themselves. It is a pretty long trek up but a lot of people do it. As long as there is an inch of snow you can board the whole way down even though some sections are pretty flat. It took about 20 mins to board/glide back to the base. For the hike up, unless there is a lot of new snow, you dont need snowshoes until the base area of the runs.
The time I made the trek we got about 2/3 of the way up when the guy working as a maintainer came by and gave us a tow up on the back of his snowmobile. That was one of the highlights of the hike up actually. =)
