Mariner Point Park in Joppa offers excellent access to the Gunpowder River and Days Cove with four concrete boat ramps (including a soft launch for kayaks and canoes), ample parking, and full amenities including restrooms, picnic areas, pavilions, and fishing piers.

The park features approximately 2 miles of nature trails and is managed by Harford County Parks and Recreation.

Note that parking can fill quickly on weekends, especially before 7 AM, and boaters should be cautious of shallow areas in the channel leading to the Chesapeake Bay.
