An all inclusive tour from San Cristobal de las Casas costs M$200 (pesos). You can also take a colectivo towards Tuxtla Gutiérrez (M$40) and ask the driver to drop you near Chiapa de Corzo. Cross the road and take another colectivo (M$5) to the 'embarcadero' where you buy a boat ticket for M$160. The boatride takes about two hours, so bring drinkingwater, a hat and sunscreen.
