Trails are amazing, the COGGS volunteers do a great job at maintaining the trails. Just make sure you stay off when the trails are wet, it makes the volunteers job way easier.
Great trails. Have trails for all levels. Easy convenient parking. Hartley is a must for Mountain bikers and hikers. You will forget you are in the middle of Duluth.
Rocks and roots mixed with hard pack. A great, if shorter, mountain bike trail.
Great views and an amazing walk regardless of the season
Nice place to hike too.
