If you have a decent pair of shoes (the path may be wet), I recommend that you take the long walk up the canyon.
Along the way, you will see a very small village on the opposite side of the river, serviced only by a small manually operated cable car over the river.
Aside from that, the sites will be more of the natural surroundings, the mountain sides, the birds, the meandering river, and local flora.
About 1.5km above the top of the waterfalls, the path will abruptly come to an end. The wide gentle river, which has been off your right side during this walk, quickly becomes a raging mountain river as it flows from its narrow canyon source.
While it may not jump out at most people who walk by, there is a rock formation that resembles that of a large salamander. But again, being a fairly large formation with a shroud of water, some people also claim it to be of other animals, but the visage stares back at you nonetheless.
The water running over its head ripples out and accentuates that of the eyes and mouth.
After Agua Azul, if you head back toward Palenque you should stop at Misol-Há. Over 35 meters high, the stunning "Sweeping Water" empties into a deep, calm pool at the base of jungle-covered cliffs. The great swim in Agua Azul compares nothing to Misol-Há experience, nor in exploring the cave behind the falls or watching the amazing rainbows!
You should also try a nice fish at the local restaurant.
It doesn't matter if you are coming from Palenque or Ocosingo direction, the bus will drop you on the main road at the Agua Azul cross-roads. It will seem like in the middle of nowhere. Just wait little bit, or if you're lucky, a pick-up will be there to take you down the road to the cascades.
Miso Ha is a group of beautiful waterfalls that you can stand in and climb through.
It is absolutely beautiful. I'd list it as one of the coolest things I've ever done ...
But only on the low areas near the shore, don't get into the currents because it is really dangerous.
Fondest memory: Nice relaxing place.
