River Street Marina
River Street Marina sits right in the heart of downtown Port Huron, tucked along the Black River with quick access to the St. Clair River. The downtown location sets it apart — you're steps from shops, restaurants, and the waterfront scene rather than out in the middle of nowhere. It's a solid base if you want to explore the area without straying far from the action of one of Michigan's most lively river towns.
