Giants Ridge is the #1-rated family vacation destination in Minnesota. Located north of Duluth in the heart of Minnesota’s unspoiled Superior National Forest of the Mesabi Iron Range, Giants Ridge offers incredible four-season fun and adventure for every level of outdoor enthusiast.


Soon to be the largest lift-served mountain bike park in the Midwest, Giants Ridge features eight purpose-built gravity (downhill) mountain bike trails, with more trails in construction throughout the 2021  season! Our lift-served downhill trails are considered beginner to advanced and are built to enhance rider enjoyment and fun!

New in 2021, Giants Ridge will offer nearly ten miles of cross country mountain bike trail winding through the dense forest terrain that surrounds Giants Ridge!
