Read all reviews on Trip Advisor, Yelp, Expedia and everything else you would have done in preparing to go to the best zip line or any outdoor activity. Now, we have a 12 year old and a 7 year old. We had to leave out the 7 year old as this is for 8 yrs and older. So it's Dad and the 12 year old out to the zip line - 1st time ever! It started out with the good ones at the beginning and slowly prepping to most enchanting experiences for the later part. The guides were very friendly, engaging and always happy to share their experiences and calming the more tensed zip liners (like me!). The experience is unbelievable and gives a definition for the very trip to Puerto Rico. Do it now. Thank me later!!!!
