Best time to visit Harrington Beach State Park

Late June through August is the most popular window, with warm Lake Michigan beach days, fully open campground loops, and long evenings at the observatory. Early September through mid-October is an excellent shoulder season for RV travel, offering cooler nights, fewer crowds, and fall color in the hardwood forest. Spring visits from mid-April to early June are quieter and good for birding, though Lake Michigan stays cold for swimming. Winter access is limited to day use, with the campground typically closed.

Things to do at Harrington Beach State Park

  • Lake Michigan Beach Easy
    RV parking available

    A long cobble and sand beach on Lake Michigan is the centerpiece of Harrington Beach State Park. Visitors swim, sunbathe, walk the shore, and watch lake freighters in the distance. Accessible boardwalks lead from a paved parking lot down to the beach.

  • Quarry Lake Trail Easy
    RV parking available

    A flat, family-friendly loop circles the spring-fed Quarry Lake formed in a former limestone quarry. The roughly 1-mile loop has interpretive signs about the park's quarrying history and offers fishing access and birding spots. Paved parking near the trailhead can fit larger vehicles.

  • Ansay Welcome Center and Picnic Area Easy
    RV parking available

    The welcome center serves as the day-use hub with restrooms, exhibits, and a large picnic area under mature trees. Picnic shelters can be reserved for groups, and the parking area accommodates trailers and motorhomes during day visits.

  • Jim and Gwen Plunkett Observatory Easy
    RV parking available

    Public stargazing programs are hosted at the on-site observatory operated by the Northern Cross Science Foundation. Evening events take advantage of the park's relatively dark skies along the Lake Michigan shoreline. Check the foundation's schedule before planning a visit.

  • Hiking and Nature Trails Easy

    Several miles of multi-use trails wind through hardwood forest, wetlands, and open meadows. Trails connect the campground, Quarry Lake, and the Lake Michigan shore for a longer loop. Most surfaces are packed dirt or grass and are suitable for casual hikers.

  • Fishing at Quarry Lake Easy
    RV parking available

    Quarry Lake is stocked and managed for shore fishing, with anglers targeting trout and panfish. A Wisconsin fishing license is required for anglers age 16 and older. Several accessible fishing spots are located along the loop trail.

  • Cross-Country Skiing and Winter Hiking Moderate

    When snow conditions allow, the park's trails are open to cross-country skiing and winter hiking. The campground is closed in winter, but day-use parking remains plowed. Bring traction devices for icy boardwalks near the lake.

James was excellent. We enjoyed our time and would definitely consider renting from him again in the future!

James H. - Aug 2026

This RV was exactly what our weekend at Road America needed. James delivered right on time and picked up promptly too. All the essentials worked perfectly and we were able to keep warm on cold days and sleep well too. I would 100% rent again from James in this area.

How to get to Harrington Beach State Park

The park is just off Interstate 43 near the village of Belgium, roughly a 40 to 45 minute drive north of Milwaukee and about 1 hour south of Green Bay. From I-43, exit at County Highway D and follow signs east toward the lake on paved county roads suitable for RVs and travel trailers. There are no tunnels, mountain passes, or steep grades on the approach, but watch for low-clearance signs in nearby small towns and use caution on the final park entrance road. The closest major airport for fly-and-rent travelers is Milwaukee Mitchell International Airport (MKE), with area RV pickups within an hour of the park.
