Jiminy Peak Mountain Resort is a great place to go with your family in the summer. I have an 18 and 20 year old who had a blast with their parents. There is stuff for families with kids ages 3 years and up.
They have a "Mountain Adventure Park" with a mountain coaster, alpine slide, giant swing, rock climbing wall, soaring eagle, Euro bungy trampoline, scenic chair lift rides, bounce house and kid climb area.
They have an aerial adventure park with 7 different courses ranging from easy to extremely difficult. They have zip lines as a part of the courses and also a separate zipline course with three ziplines and the leap of faith. The black course's (the most difficult course) fourth element is the hardest part of any of the courses. I worked hard to complete this element. The person after me had to be rescued.
I was happy to see that they had plenty of free water stations around the courses, and they encouraged you to stay hydrated. They also have a free playground perfect for the younger children.
The mountain also has hiking and mountain biking as potential activities for visiting families.
