The center of Mirror Lake village is the junction of Tuftonboro Neck Road with the Governor Wentworth Highway. The Mirror Lake Community Church, which only holds services in summer, is in the village center. At one time Mirror Lake had a mill and a general store named "Ernest B. Piper, Groceries and Stuff" which closed in 1969. The village is known for its summer camps, of which there are 5, and for its summer cabin complexes. The village got brief international attention in 2000, when local innkeeper Chuck Diorio positively identified Massachusetts murderer Dr. Richard Sharpe, who was arrested at the Pine View Lodge in Melvin Village.
The small village of Union Wharf lies just north of Mirror Lake, centered on an old dock and marina in 19 Mile Bay. Today Union Wharf houses a summer grocer, boat gasoline pumps, around 70 boat slips and a public beach. The area was once dominated by Nineteen Mile Bay Lodges, a summer cabin renter, which has since become a private property. It is known for its knotty pine cabins, built in the 1950s by Leon Proverb, using mostly materials from Charlestown Navy Yard in Massachusetts.
