We did canopy tour last Nov cruising on Carnival Spirit. The canopy tour offered was through Vallarta Adventures. Took about an hour to get there from terminal. All the staff were friendly, kowledgable and skillfull. I felt very safe. Always double tetherd when on the cable. Never untethered. This staff was trained at the canopy location in Costa Rica which is supposed to be more challenging than this one. Hope this helps.
