Sauna. Camp Van Vac's 90-year-old sauna tradition moved recently to its new, scenic spot overlooking Burntside, making it so easy to "Go jump in the lake!" The sauna is in its own cabin now, and it's fired up and ready for you Sunday, Tuesday, and Thursday nights during July and August. Kids are welcome from 7-9 pm, and adults get the place to themselves from 9-11 pm. In May, June, and September, the sauna is hot on Saturday and one other night during the week.
