Rose Mountain views of Mount Monadnock.

The small New Hampshire town of Lyndeborough is dispersed across an area north east of Milford, and encompasses several moderate mountain peaks. This route explores three of them, offers tranquil - likely solitary - woodland hiking and unique scenic views of neighboring mountains that may be more familiar with New Hampshire hikers. Our map also offers a shorter hiking option to the summit of The Pinnacle via a partial loop.

The Mountain Road trailhead is unmarked, with a few roadside parking slots just to the south. Heading gradually uphill to The Pinnacle, the trail is mostly easy going with very few rock and roots, the surface often cushioned by blankets of pine needles. Around half the way up the mountain is a junction leading to Helen's trail - we suggest bearing left and continuing on the main path and returning along Helen's trail.

Views from mostly wooded summit of The Pinnacle (1,703 ft) are partial at best, but if you continue around this domed peak you will find a viewpoint that looks towards the white spherical radomes of New Boston Space Force Base. Further around the bend you'll also happen upon a more spectacular view that spans the horizon from Monadnock to Kearsarge Mountains. We've marked these spots on our map.

If you choose to continue beyond The Pinnacle to bag the peaks of Lyndeborough (1,640 ft) and Rose (1,720 ft) mountains, you'll be doing so along wide snowmobile trails that offer easy going without much further elevation gain. We enjoyed the feeling of trekking deeper into the forest and further away from civilization. There are plenty of signs that these trails can be well-used however, including firepits on mountain peaks and even the remains of a long-abandoned motor car.

Lyndeborough Mountain's wide and exposed summit requires a short out-and-back diversion off the main trail. Continuing to Rose Mountain rewards with the best of the scenic viewpoints, but note that you'll have to continue a little beyond the summit to find it.

Trail conditions were especially easy for New Hampshire, with few rocky sections to traverse. Despite the solitude you're likely to find in these mountains, the trails are wide and well-trodden enough that ticks are unlikely.
