Some of Wisconsin's most interesting state parks are also its quietest. Tower Hill State Park, inside the village of Spring Green about an hour west of Madison, covers just 77 acres along the Wisconsin River — and in 2023 it ranked as the state's third-least visited park, according to the Milwaukee Journal Sentinel. For anyone who likes their outdoor escapes uncrowded, that's the selling point.
The park's claim to fame is its history. A 1.1-mile loop trail climbs roughly 183 feet to a 180-foot shot tower and a replica of the smelting house, where in the 1830s a six-man crew dropped thousands of pounds of molten lead down the shaft to make shot for firearms. Only a fraction of each day's 5,000-pound output was actually usable, per the Wisconsin Department of Natural Resources, but the operation shaped the area's early industry. The trailhead starts at the campground, and while the route is rated easy, parts of the climb turn into stairs.
Camping here is deliberately simple. The seasonal campground has just 10 tent sites, all reservation-only — no walk-ins, no RV hookups, no showers. You get a vault toilet, water spigots that run from Memorial Day weekend through October, and firewood available on site. There are also picnic areas, a pavilion and a gazebo for day visitors. If that sounds too rustic, the village of Spring Green is a five-minute drive away with more accommodation options, though you'd be missing the point of sleeping beside the river.
The Wisconsin River itself is the main draw. Paddlers launch kayaks and canoes onto the river and its backwaters, and anglers with a license can target walleye, smallmouth bass, northern pike, bluegill and several catfish species. Birdwatchers do well in every season: spring brings yellow-rumped warblers, wild turkeys and chipping sparrows; summer brings great blue herons and eastern wood peewees; and blue jays, northern cardinals and downy woodpeckers stick around year-round.
Practicalities are easy. The park never closes, but from Columbus Day weekend until mid-May you'll need to park at the entrance and walk in, as vehicle access is seasonal. From Madison it's under an hour by car; from Milwaukee, about two. The trail network totals around two miles of bluff and riverside paths, including a half-mile nature trail, so a weekend is plenty — or pair it with a wider Wisconsin River road trip, since the waterway passes several parks with sandstone cliffs and Native American mounds along its 430-mile course.
Tower Hill suits campers who want a genuine digital detox without a long drive, birders chasing seasonal migrations, and history buffs who enjoy their heritage sites with a view. Just book that campsite ahead — with only ten, they go fast in high season.
