We did the zip lining at Climbworks about 3 weeks ago and LOVED it!! My daughters are 8 and 10, and my very fit mid-70s parents did it with us! We wore Keens and they worked out very well. They are easy to clean up if you get muddy, which we did a little (others who did Climbworks said they got super muddy since they went after some rain). Definitely minimize the shoes... They take up so much room!!! Have fun!!
