Hillsborough County, New Hampshire

Southern New Hampshire is home to Hillsborough County, the most populous in the state. Manchester is the largest city and is a former mill town turned tech hub. That means you have bustling city life and quiet farmland within a short drive.
Nashua, near the Massachusetts border, offers a mix of history and modern amenities. The Merrimack River runs through the heart of the county. Politics comes alive here during primary season. Everyone has an opinion.
Mount Monadnock looms on the western edge. Local breweries are making a name for themselves. Small towns like Peterborough have a strong arts scene. It’s not all work though because you’ll find plenty of folks out fishing on the weekends or cheering on the Fisher Cats at the ballpark.
