Hola!
For my english speaking friends, here is the summary for Mexico.
My start was like a shock, I didn't expected a humidity and a heat like this. So the first days I tried to adapt to the new climate. And I hated Cancun, never seen so many hotels at one place. Can't believe people spend holidays there. So as soon as possible I got out of there and went to Isla Mujeres and had relaxing days with some new friends on a nice little island.
My first highlight there was a whale shark watching tour and we had herds of 50 to 100 of them. So so impressive, still can't believe that I swam right between those beautiful giants. This island was as well a good spot for diving, so I did some exploring under water at the wreck and at some of the shark places. One dive spot offered giant turtles which was another highlight.
After sun and water sports I went to see some of those well-known Maya ruins in Chichén Itzá and Ek Balam. Even Chichen Itza is one of the new seven world wonders, it was too crowded for me so the point went to Ek Balam. This site was less touristy and had a cenote to refresh nearby.
I stayed in town called Valladolid and I can recommend this as a good hub to explore all the ruins around. And it's a nice little town with more locals than tourists! ;-)
From there it was only a short ride to the ruins of Coba on my way down to Tulum. It was a good decision to take bike on this archeological site because the temples and pyramids are quite far from each other.
When I reached Tulum I immediately signed up for the cenote diving which I was so excited to do. And it was amazing! Saw six different cenotes and it was really worth the money. "Angelita" pit was one of the weirdest places I've ever been to and "Taj Maha" one of the most beautiful places where the halocline effect let the rays of sunlight playing games under water.
For sure I did as well the tour to the ruins and took the most famous picture of the ruin with the turquoise water.
Then I changed my plan and went down to Chiapas to see more of Mexico because everybody recommended it to me. And it turned out that I enjoyed Chiapas very much. I loved the Palenque ruins, less tourists, nice weather and all pyramids could be climbed! And I did a tour to some nice waterfalls Agua Azul and Mizol Ha to see something different than only ruins.
After only two days there I continued to San Cristobal which is a lovely town in the mountains and I stayed longer than planned. It was quite cold but so very interesting. There are a lot of old still existing Maya communities around and to visit them was amazing. There is a church that is not a normal church, they do strange rituals with chicken and pepsi in there. Crazy! Had such a great time and finished my Mexican tour with a ride through canyon Sumidero. The landscape was breathtaking and at the end of the tour we even saw crocodiles on the riverbank.
So I can say what a start in my first country on the list... :-)
I continued my trip down the Panamerican Highway into Guatemala but this will be another post.
