Almost a week into our whirlwind trip, Mexico was far from the sun-drenched desert I had pictured in my mind. We’d experienced the vibrancy of Mexico City, the colours of Cholula and Puebla, and the incredible ruins and food of Oaxaca. Now, we were heading into the rainforest! The state of Chiapas is home to the stunning Sumidero Canyon, where we stopped off for an exhilarating speedboat ride on our way to San Cristobal.
