If your asking about the zip line I don't think there is an age limit, just a weight limit if at least 70 pounds. And if your child doesn't weigh that much they ad weights to make sure smaller kids have enough momentum. There is defiantly no riding together on the zip lines unless going tandem. (Side by side ). They van accompany you during the cave tour though. Hope this helps.
If you are talking about the zip line, yes kids under a certain weight must ride tandom with an adult.
No age limit just weight limit
Over 70 lbs solo under wiil require tandem
