I am very slow at getting these images up, sorry about that.
On day 4 we did what any vacationer would do, we laid on the beach all morning.
In the afternoon we did a cenote dive. Basically, we went scuba diving in an underwater cave! Pretty awesome. We could see the exit at all times so we didn't need cave diving certification, thank goodness. If you ever make it to the Yucatan you can't miss this opportunity.
This particular cenote was called Taj Mahal, a system of three cenotes.
We ended the day with a long walk along the beach at sunset, perfect.
