There are many object (tree) courses in the Flagstaff area. The most popular being the “Lake Mary” course and the “Old Munds” course.
We are currently on the lookout for course maps for these two as well as more information on those players who have created object courses they wish to share.
***Please be aware that object courses on private land and forest service land are illegal by nature. The Forest Service considers an object-style disc golf course an unauthorized use of Forest Service property. Officially, the Forest Service has a process for introducing new activities onto the forest – you have to apply for a special use permit, conduct an NEPA (environmental impact) study, plus more red tape. It’s a law put there to regulate what happens on federal lands.
