EdV on 10/30/2019 The predominant language on Cozumel is Spanish (Mexican Spanish. Castellano from Spain is slightly different and not what is used here), although you may also hear Mayan on the island. There are also many people that speak English as a first or second language. If you are English speaking and staying in the main tourist area, you'll manage fairly well. However, just in case, you'll find a link to a translator in the "Mi Vida" section. Most translators do not work perfectly but they will usually help when needed and this particular one is quite accurate. Keep in mind the translator will need WiFi or data to function as it is a linked website.
