We also did a quick morning trip to the Mayan site of Coban which is interesting mainly because it is set amidst the jungle and also has a rather different pyramid structure compared to the other pyramids we have seen so far - so of course we had to go there and climb it!
On the way back from Coban we paid a visit to the "Grand Cenote" - an inland water filled sinkhole that you can dive and snorkel in. It was fabulous for a quick dip to cool off from the midday sun and the waters were wonderfully clear.
