Chiapas is one of my favourite states of Mexico. It is the most activist, where live the most indigenous population of the country and include a lot of nature. The main cities are Tuxtla Gutiérrez, San Cristobal and Palenque. There is a huge climate difference between the south which is fresh and dry and the north (Palenque) which is very warm and humid.
I also like it because it is very cheap compared to neighboring states such as Oaxaca and Quintana Roo. Because of the wonderful nature, you can enjoy outdoor activities such as hikes, waterfalls, canyons, caves, rivers, zip lining and way more. Don’t forget about the rainy season in Mexico that extend from May to September. Enjoy those adventure activities I recommend you in my dear Chiapas.
