My 6 1/2 yo sons are traveling to guanacaste with us. The tour companies will take children as young as age 4 on the zip lines! I'm not completely comfortable with taking my children on a canopy tour but don't want to regret missing out on this experience if it's very safe, fun, and most kids love it. I'm trying to gauge if it's common for 6 yo to zip line. We are leaving in less than 3 weeks.
