Best Time to Camp at Savanna Campground

Each season paints the park in new colors and possibilities. Summer brings warm days perfect for casting a line, paddling the river's glassy surface, and enjoying full visitor services. Fall transforms the hillsides into a tapestry of gold and crimson, with comfortable temperatures ideal for hiking. When winter's snow blankets the trails, adventurers strap on snowshoes and cross-country skis, and hardy campers discover the magic of winter camping. Two cozy cabins welcome guests year-round, while two additional seasonal cabins open their doors from April through October.
