I live in the northern Yucatan area, and have navigated the area many times both towards Cancun
and down to Belize
, and towards Sisal, Celestun and Campeche. I'm in the process of making a guide for cruisers of the area, because it is a very nice area to cruise
, but also safe quiet and with lots of things to see and do at very low cost. My page is called Yucatan Cruising Guide, and is not finished, but can give you and idea of what to see and how to get there in the north part of the Yucatan Peninsula.
