The Millbrook Valley Trails network (see trail map) includes over 13km of trails that follow the shoreline of Baxter Creek, a cold-water stream that originates on the Oak Ridges Moraine. Baxter Creek is a tributary of the Otonabee River and provides habitat for a variety of species. The trails wind through valleys, forests, wetlands, and meadows providing scenic views and a connection to the Ganaraska Forest.

Two of the trail heads are located adjacent to the millpond:

Baxter Creek Trail (3km) The trail begins beside the Millbrook millpond close to historic Needlers Mill. It follows the pond and Baxter creek through magnificent cedar forests, crosses a floating boardwalk over a wetland and through meadows.

Medds Mountain Trail (0.6km) The trail begins from Medds Mountain park and follows the shores of the millpond and Baxter Creek before looping through the surrounding old-growth deciduous forest.
