How to get there? Hop on to an ADO bus to Bacalar.
Where to stay? I got recommended the Green Monkey and I loved it there. I camped in my own tent and every morning I would unzip it for the sun rise. You can also hire tents there, sleep in dorms or in a bus. If I didn’t have my tent I would have slept on the bus, its an old American school bus that they have turned into a dorm, with beds and fly nets.
Where to eat? The hostel had a kitchen, but there is also lots of food places in town.
What to do? You have to do the sunrise stand up paddle board tour. It was magical and so cheap.
Extra info.. Great stop over place before heading for Belize.
On my second time in Mexico after Bacalar I headed over to Belize, but your other option would be to head up north into the Jungle, Palenque. You will be waking up to the sound of Howler Monkeys.
