Hike up to the viewpoint. About halfway up there is a chair lift that will take you to the very top. It is a fairly easy hike. The ski lift is older and played disco music when I was there. The view is amazing! You can see a lot of the lake from there. Worth the trip.
Also, take a boat trip for an hour (or more) to get a better view of the lake and some other towns on the lake. It is lovely!
