Most visited place was “Old man in the mountain" is no more there. You can go for hiking, you can rent kayak, there are couple beautiful lake and you can go for ferry ride in Laconia. It solely depends on your interest. We are thinking of Newfound Lake in Bristol for overnight. You can visit Mt.Washington, you will get a sticker, and this car has been climbed to Mt Washington. Enjoy the trip. If you are interested in cities, it is not great but couple times these cities had been chosen for the must livable city in us. Nashua, Portsmouth and Manchester were in the top 10 list.
