Sweden Point Marina at Smallwood State Park offers six boat launch ramps with a $10/day launch fee for in-state visitors, accommodating access to Mattawoman Creek and the nearby Potomac River.

The facility features a concession store with fuel, ice, bait and tackle, and a marina with 50 wet slips available for both long-term and transient (up to 2 weeks) rentals.

Boat ramps are open during park hours only, and visitors wishing to remain on the water past sunset must complete a Float Plan Form.
