“The Key West of the Midwest,” located on the Mississippi River in Illinois along the Lewis and Clark Trail!

Throughout history, the Mississippi and Illinois Rivers influenced travelers in many ways – and even aided the Corps of Discovery on their expedition westward – but in May of 2006, travelers from around the world began to enjoy their journey in an even greater way and, thus, Grafton Harbor was born!

Whether traveling by land or water, our five-anchor marina boasts being “The Harbor of Hospitality.” Grafton Harbor invites visitors to experience marina life at its finest. Whether you have your own small pleasure craft or mega-yacht, Grafton Harbor can accommodate your needs.

A floating swimming pool and hot tub, sanitary slip and slide pump-out, spacious gated concrete docks, Wi-Fi, satellite TV, concierge dock service and family festivities are just a few of the royal amenities visitors can enjoy on a trip to Grafton Harbor.
