Cenotes!

went to very cool string of cenotes (big sinkholes) yesterday- was given half a line in the guidebook, but was a brilliant day. The village had put in rails between all the cenotes and made loads of mini carriages which were pulled by horses.

Yucatan doesn´t have any rivers, so cenotes are very important for water. One of them had a massive tree right above it with roots growing right down into the water...
