I'm missing my map but I think this is not too far away> The Hamlin Conservation Area. See
www.meredithnh.org for details in the Park & Rec section.
This is a short excerpt from my 02/02/2007 Trail report which mentions the roads to the trailhead.
The roads take a little to navigate but it's only about five miles or so off Route 104 (& five miles off Route 93). Trails are well signed & easy to follow, several options for hikes of different lengths. Property was formerly owned by a doctor who retired to Florida & gave the land to the town. View from Crockett's Ledge overlooks Wicas Lake & part of Winnisquam (I think) saw & heard a couple of snowmobiles on the lake below me, this would be a great fall hike with peak color.
