One of the natural jewels of Mexico, Sumidero Canyon is a splendid and impressive place that's sure to leave many who visit it absolutely amazed.
My suggestion:
Take a boat trip deep into the heart of the canyon: it's a simply unforgettable experience!
Summary:
Located a few kilometers from the city of Tuxtla Gutiérrez in southern Mexico,
Sumidero Canyon, which reaches 1,000 meters in depth in places, is one of the wonders of the state of Chiapas. Once at the landing stage, I climbed aboard a little motorboat with space for around twenty people. As we followed the contours of this natural fault this little jaunt along the water gave me the opportunity to see and admire crocodiles, all kinds of species of birds, and the various wildlife that populates the banks.
