The Tree Farm Trail system is my favorite trail in the Detroit metro area. Relatively flat, but the 10 mile singletrack loop is jam packed with features (log piles, bridges, technical sections, "skinny" tree balance beams, rock gardens, pump track, craters, etc).
The singletrack loop intersects with an assortment of multi-use trails that are wider and great for family bike rides and hikes. The trails are well marked at each intersection and most of the difficult sections have a bi-pass option. Novi Lakeshore park is beautiful with picnic areas, playgrounds, bathrooms and even a beach on Walled Lake. It sits less than a mile north of Novi's huge shopping district and 12-Oaks Mall. You can easily bike/walk on sidewalks all the way into town for a bite to eat or go see a movie.
Started at Lakeshore Park which has a play structure, then when you hike/bike in a bit further it has another play structure. Kids loved that. Hiking was great. A lot of mountain bikers around who were very polite, they use separate trails so no issue with hiking where we wanted to go. Cold day so we didn't go as far as we had hoped, but will definitely come back. No fee on the day we came because the fee booth wasn't manned at the time.
This was my first time riding on this trail. The trail is not super hard - I rate myself as a beginner to close to intermediate. I had no problem riding but there are a couple of really challenging spots on this trail. I actually flipped once. The trail markers are fine 90% of the time - just keep following the orange color arrows (markers). There is one split that is very confusing. By the 8th mile marker there is little area with a bunch of obstacles, little hills, etc. similar to the skate boarding pits - I saw a bunch of kids there having lots of fun. I really liked the trail because of its beauty , actually saw a couple of dears there.

Hiked on the bike trail and ask if the bikers were very courteous. Did the full 10 miles and really enjoyed the varied scenery and micro ecosystems.
