I am with Trish and Alex!, I have been camping in the whites long before my youngest was born she is 6 now. My oldest now 15 did washington in a day via tucks when he was 8. My 10 year old has been up to tucks and They have all done numerous trips up to MT Willard.
Since I climb we also do alot of climbers trails, several on the Kanc, for those no people kind of days. It is really all about how comfortable the parents are and one thing for sure PARENTS KNOW THEIR KIDS ABILITIES, we have raised them and played with them. They are all different and require different paces and teaching skills.
I would rather have them cold and wet on a hike then soft and squisey on the couch. They love and look forward to getting out. This year we will all winter camp at a lean-to in CT. My 15 year old will start winterpack backing with me this season.
Teach them well and they will be the wiser!
