Hi there Kjai,
My wife and I did the canopy tour in Jamaica. It was great, very exciting!. Redundant safety systems, equipment in good condition and knowledgable guides. It does involve some hiking in warm weather, and a little light climbing, but as long as you're not a complete couch potato and O.K. with heights (some spans are 200-300 ft. above the ground) you'll be fine. They'll have bug spray for you to use once you're there and cold beer and jerk chicken to buy when you're done. We'll probably do this again on our next cruise.
