These Mayan ruins were very impressive. There are quite a few buildings exposed and we were able to climb up a couple of them, the biggest being El Castillo. From the top, we could see Guatamala - it was an incredible view, and unfortunately, it was raining that day, so it was hazy, but on a clear day it must be breathtaking. The only word of caution is that it is quite a climb up and down. There are no railings, as they are old structures and you are very close to the edge and very high up. Because of the rain, the steps were very slippery and it was a treacherous climb down.
