Soo Line Trail / Onamia MN KOA is located less than a mile off US Hwy 169 in Onamia, Minnesota. We offer RV sites for all sizes, spacious tent sites and comfortable rooms in our lodge, giving you many options for your stay. The Soo Line Trail runs directly through the campground property giving you direct access to explore on ATVs, bicycles and hiking. In addition to the trail, our wide-open spaces, outdoor recreation amenities, themed weekends, and planned kids' activities all provide plenty of family fun. For the fisherman and water sports enthusiasts, we are right down the road from beautiful Mille Lacs Lake. If you're looking for some indoor excitement, the Grand Casino Mille Lacs is just minutes away. Whether you are ATVing, fishing, hiking, or just relaxing, we provide the place for you.
