Welcome to Grafton Harbor Marina on the Great Loop

Tie up for the night or stay awhile. With protected docks, glowing river sunsets, great food and drinks, and an easygoing local vibe, Grafton Harbor Marina on the Great Loop is made for slowing down and enjoying the river.

Step ashore for sunset cruises, an on-site winery, a floating bar, and a well-loved ship store. Grab a seat at the Grafton Oyster Bar, open nearly year-round, with St. Louis and nearby attractions just a short trip away before heading back out on the water.
