Trail Overview

Mill Brook is an easy, scenic 2.8-mile spur trail in the White Mountain National Forest, making it perfect for beginners, stock high-clearance vehicles, and scenic-seeking drivers looking to escape the crowds. Traveling through a quiet corridor of dense northern hardwoods, this route features a well-maintained gravel surface that transitions into double-track in some areas, offering a peaceful drive with very light traffic. The route sits between 1,410 and 1,730 feet in elevation, presenting an easy grade with minor potholes and gentle dips that require no advanced technical skills. Any standard four-wheel-drive vehicle, SUV, or SxS can easily navigate this road during the dry summer and colorful autumn seasons. The drive eventually concludes at a turnaround point where large boulders block the remainder of the old roadway, which was washed out by the nearby stream. From this turnaround, visitors can transition to foot travel as a hiking trail continues down the historic corridor, offering an excellent opportunity to explore further into the scenic forest. Because the route is located in the White Mountain National Forest, visitors should be aware of seasonal gate closures, especially during the muddy spring and snowy winter months when access is restricted. It is highly recommended to combine this short drive with neighboring forest roads or nearby hiking trailheads, such as those leading toward Mount Martha or Cherry Mountain, to make a full day of backcountry exploration.
