My husband and a friend, both in their upper 60's, wanted to try zip lining while in Cozumel on a cruise port stop. We were referred to Ecoparque Cuzam by a street tout while strolling in the main square.
We found the staff very professional and helpful, giving my friend extra encouragement after she was hesitating. The price was fair (second rider got a discount) and the ride was loads of fun. It was an easy taxi ride from the town center.
