6yrs an older, an no they can't ride with parent. My 7yr old did Great for his first time riding!
A child that is 6 and older may have their own ATV. 2 years to 5, you can rent a cart and they'll ride inside that cart. May be a bit boring for them. At least it was for my daughter.
I believe it was under 6 will have to ride in a cart pulled by parent. My 10yo was just about the right age to be on his own, there were some younger kids riding solo but they were having a little trouble getting going.
