Mason Springs Soft Launch is a free, non-motorized vessel access point on Mattawoman Creek featuring a gravel parking lot (approximately 10 spaces) and a dirt portage trail of about 75 yards to the water's edge.

Open dawn to dusk daily, this site is ideal for kayakers and canoeists accessing the extensive wetlands and estuary of Mattawoman Creek, though it requires carrying boats to the launch point rather than using a traditional ramp.
