Twin Mountain and the Town of Carroll, incorporated in 1832 and including Twin Mountain, Bretton Woods, Fabyans, and Crawfords, grew from early settlement based on farming, timbering, and trout fishing in the Ammonoosuc River and its tributaries into a tourism and transportation center shaped by roads, railroads, grand hotels, and mountain travel. By 1806, the 10th New Hampshire Turnpike connected Portland, Maine, to the Connecticut River Valley and made stagecoach travel possible, while visiting writers and artists helped spark a tourism industry that has continued ever since. The Boston, Concord & Montreal Railroad in 1875 and the Portland & Ogdensburg Railroad in 1876 opened passenger service to a wider public, and Fabyans became the main railroad hub, delivering hundreds of visitors each week and linking to a spur at the base of the Mount Washington Cog Railway. Opened in 1869, the world's first mountain-climbing cog railway carried travelers toward the 6,288-foot summit of Mount Washington and became known as the Railway to the Moon. The region also supported a thriving timber market through four logging railroads and the now vanished towns of Livermore, Carrigain, and Zealand. Grand hotels including Crawford House, Fabyan House, Mount Pleasant House, The Twin Mountain House, and the Mount Washington Hotel catered to wealthy summer guests, but changing times and fires led to the disappearance of all but one. The historic Mount Washington Hotel, together with inns, motels, cottages, campgrounds, the Tip Top House atop Mount Washington, the Lakes of the Clouds AMC hut, and enduring features such as the Ammonoosuc River, continues a long tradition of mountain hospitality in a rugged landscape.
