It’s important to be respectful of local customs in this part of Mexico. Indigenous villages are often extremely close-knit, and their people can be suspicious of outsiders and particularly sensitive about having their photo taken. In some villages cameras are, at best, tolerated – and sometimes not even that. You may put yourself in physical danger by taking photos without permission. If in any doubt, ask first.
This part of Mexico tends to ignore daylight saving time, as do colectivo companies that originate in cities like Comitán and Palenque that service the region. From April through October, check your watch against the company’s to double-check transportation schedules. If they’re using ‘God’s time,’ you’ll be departing an hour later than the official ‘government time.’
