Lake Hopatcong State Park offers public shore access to New Jersey's largest freshwater lake with a boat launch facility available for motorboats, kayaks, sailboats, and jet skis.

The day-use area features parking (fills quickly on busy days), picnic areas with grills, restrooms with showers, a concession stand, and recreational courts; note that entrance fees apply Memorial Day through Labor Day.

Swimming is lifeguard-supervised Wednesday-Sunday from 10am-9:30pm during summer months, and the park opens at 8am daily.
