Hmm, I know there are canopy tours in Costa Rica, Belize, Roatan, Puerto Vallarta to name a few, but I do not believe there is any in Costa Maya. I know Carnival offers a jungle tour that includes a canopy tour in Chick-ha from Calica/Playa del Carmen, but I think that is the closest.
Regarding the canopy tour from Playa del Carmen, would I be closer to that from Cozumel or Costa Maya? I'm going to both spots. The kids want to do the cave tubing in Belize. Do you know if it would be possible to do both the canopy tour & cave tubing in Belize on the one day?
Cozumel is an island off the Yucatan peninsula; Riviera Maya and Costa Maya are both on the Yucatan (and may be somewhat the same thing). So you'd be closer from Costa Maya.
