Hopatcong State Park offers a boat launch facility for accessing Lake Hopatcong, New Jersey's largest lake at 2,500 acres.

The park features a boat ramp (noted as steep with maintenance concerns), parking areas, and amenities including picnic facilities, restrooms with showers, and a concession stand.

Day-use fees apply seasonally (Memorial Day through Labor Day), with separate boat launch fees of $12 for NJ residents and $20 for out-of-state visitors during peak season.
