Im traveling with someone who wont be zip lining is there something for them to do

Kayaking on Mill Creek is only for two hours. But in the middle of the day is hot with little or no shade. Underground kayaking, the skylift or hiking are all good options. I don't know of much else to do close by.

Sky lift over the natural bridge and gorge, or kayaking.

Try the underground cavern boat tour its not far from there either
