Cuxama cenotes

Hello.

We will be staying on Merida in November this year. I hear a good day trip from Merida is the 3 cenotes at Cuzama. Apparently you can get there by horse cart too?

Can anyone please give me more info?

Can we get a bus to Cuzama from Merida or is it best to do as part of an organised day trip from Merida.

Any advice is greatly appreciated:-)
