Squam Lake Science Center in Holderness is a great hands on science and nature museum.
Smitty's CInema Pub in Tilton (west of the highway toward Franklin) serves reasonable family friendly meals and drinks for the adults in comfy seats, I think maybe cafe tables, while you watch the movie. A unique dining and movie experience.
Also I was wondering is there any easter eggs hunts for the kids in the area Easter day? And any recommended outdoor adventure activities (weather permitting) close by (within a maximum1 hour drive)
