You can get to Cuzama by either bus or by car. If you have rented a car, Cuzama is easy to get to from Mérida. It takes about 45 minutes to get to the town of Cuzuma. Once you arrive in Cuzama, make a right turn at the town square. This is where the church and town hall are located. Look for the road that leads towards Chunkanán and the cenotes' entrance. If you are going by bus, you will want to go to the Noreste bus terminal in Mérida. This is the second class bus terminal which is located at Calle 50 x 65 x 67. The bus will cost around 32 pesos as of 2010. There are colectivos near the bus station which will also take you to Cuzama. As of March 2011 the colectivos to Cuzama were at Calle 67 between calles 50 and 52 but their location can change; just ask any driver and they should point you in the right direction. The colectivos (white vans) are generally cheaper and faster (24 pesos, Dec 2015). They may seem more intimidating, but the colectivo drivers for Cuzama will approach you and ask you if you are going to Cuzama so it's pretty easy. The colectivos back to Merida leave from the same spot that they will drop you off at in Cuzama. You may also consider taking a tour to Cuzama, which is easy, but not necessary.
The cenote entrance is about 3.3 km (2 miles) from the center of Cuzama. If you took a bus or colectivo to Cuzama, this is where you will be dropped off (in front of the church). You can either walk (follow the signs) or take a mototaxi. The mototaxi drivers will likely charge you 60 pesos each way.
The mototaxi drivers will take you to the start of a rail track where horse-drawn carts will transport you to the three cenotes. You will be charged 350 pesos (Dec 2015) in total, so the more people in your group; the less per person. Once you get to the main track a guide will look after you for the rest of the trip; dealing with the horse/cart, leading you to the cenotes, providing torches in the dark etc.
Visiting all three cenotes from start to finish will take ~ 3 hours so consider bringing snacks and water. For an article that does a decent job of explaining more about the cenotes, see .
Before you take the tour, you can ask the household in the one and only store to cook for you. There are only two choices: chicken and poc chuc, a Yucatecan tender pork dish. The chicken is good, but the poc chuc is really special.
As you usually eat on your way back from the Cenotes, you can get there really hungry; consider asking for two dishes instead of one. The price is really cheap, about $US 3.00 only.
Drink? For something different, try one of Yucatan's brand sodas: Krystal. Different flavours, some unusual, about $8 Mexican pesos.
