It's a must!. All Mayan ruin cities have their own personality and Coba is not an exception. What is special about this one. Is that is the tallest ruin in the Riviera Maya and you can climb it!. The view is incredible and so worth it when your at the top. You have to experience it yourself. For a great experience these are a must. Sun block,mosquito repellent, drinking water and a camera. Inside the park get a guide & a taxi bicycle. The ruins are in the jungle and are far apart from each other, it is a big city. You can rent a bike but it gets hot. You will be glad you took the taxi bicycle. The ruins don't have placards explaining what you are looking at. That is why I recommend getting the guide. Remember you can bargain with the tour guide. So get ready for some great pictures!
