If you are interested in the Lakes Region, you might think about Meredith or Wolfeboro both quaint lakeside towns on opposite sides of Lake Winnipesaukee.
You could take an evening dinner cruise on the MV Mt. Washington on Lake Winnipesaukee and stay overnight at Church Landing, a very nice hotel on Meredith Bay or one of the many Inns in Wolfeboro. There are lots of good restaurants in each town.
The next day you could visit Castle in the Clouds or ride the chairlift to the top of the Gunstock mountain for beautiful views of the numerous islands on Lake Winnipesaukee before heading back. You will see why Mitt Romney, the Marriotts and other famous people all have their summer homes here and why Pres. Sarkozy from France vacationed here. These towns are about an hour and half from Lowell.
