Gunpowder Falls State Park's Dundee Creek Marina offers two double-wide boat launching lanes with courtesy docks and parking for approximately 100 boat trailers, plus a free small-craft launch area for kayaks, canoes, and paddleboards.

The facility charges $10 for Maryland residents ($12 for non-residents) and operates seasonally from April through November, with extended hours during summer months (5 am to sunset Memorial Day through Labor Day).

A marina store and overnight passes are available for multi-day trips.
