The Cresset is a very large complex that has educational , recreational and commercial facilities. The Key Theatre is on the riverbank and does plays and live entertainment. For some fun and relaxation you can visit the Miller State Park where the summit reaches 2,288 feet. You may want to rent a car for this adventure!
Then there is Temple Mountain for skiers. It is one of the oldest ski areas in the States but not is shut down. However, it is used to hike and for the scenery. If it is sweets you want then you will find all you are looking for with a visit to the Ava Marie Handmade Chocolates which is a speciality shop in Peterborough.
