The Ephraim Yacht Harbor is located in the heart of Door County on the protected waters of Eagle Harbor, just across from the limestone bluffs of Peninsula State Park and Horseshoe Island on Lake Michigan's Green Bay. Our location offers boaters the opportunity to visit this quaint village, explore Peninsula State Park, and watch the most breathtaking sunsets in all of Door County. Enjoy cruising over 250 miles of the Door County shoreline, bays, islands and villages. We are centered between Egg Harbor, Fish Creek, Sister Bay, and Ellison Bay; close to Horseshoe, Chambers and Washington Islands. Whatever your cruising plans are, our helpful and courteous Dock Master and staff will be able to assist you with both transient and annual slips, fuel, water, ice, laundry and more.
