Mountain bikes need to ride the loop counterclockwise.
The Mount Marquette Loop (also known to locals as the Blue Loop because of the classic blue NTN arrow signs which mark the trail) is one of the signature technical trails in the Marquette singletrack system. The trail is rated as moderately difficult with numerous short more difficult sections and one longer more difficult section (there is a bypass for this).
The loop is just under four miles in length and there are a number of adjacent nearby trails available to extend a ride. There are four main access points: the M-553 main NTN South Trails trailhead, the base of the Mt. Marquette access road, Shiras Park, and the Granite Pointe neighborhood access. The M553 trailhead is the most used access point as it is the hub of the South Trails system.
From the parking area, the trail should be ridden in a counterclockwise direction. The large billboard sign marks the beginning of the trail. The loop contains a number of named segments.
