Best time to visit Cañón del Sumidero National Park
The general pattern for Cañón del Sumidero National Park is simple: December through April, the drier and less humid stretch is the window most visitors want, and May and November gives you most of it with fewer people.
Peak window
The window most visitors want is December through April, the drier and less humid stretch. A sheer-walled canyon cut by the Grijalva River above Chiapa de Corzo. Boat trips and rim overlooks are the usual way to see the cliffs.
Shoulder season
The shoulder runs May and November — fewer people, shorter days, and a real chance of weather. Usually the better trade if you are flexible.
The thing that ruins trips here
Heat and humidity are constant. Plan activity for early morning and carry more water than feels necessary.
Check before you commit
Seasonal windows shift year to year, and road and trail openings depend on that year's weather. Confirm current conditions on the official park site before booking anything you cannot change.
