I know there is more, however I can't remember them all. Maybe Brandi can remember more than me.

The favorite one with kids is Manitou Cave with True Adventure Sports. TAS has a way with kids. My kids and Brandi's kids beg to go and do an adventure with TAS. The things we have done with them: night hike (great fun), rappelling, Appalacian Trail Hike, Survival Class.
