Free diving with humpback whales.
I used to work for a boat that did guided trips to swim with the hump back whales in the silver banks, just north of the Dominican Republic. Normally you can’t dive down on them. They will split. You can just float in the water above them. These guys were super chill and didn’t mind. Plus it was just me and the photographer in the water while the guests were having lunch, so I could get away with diving. The photographer kept wanting me to get closer, for his shot, but those are damn big animals. The mother whale was full frame in my mask and the baby was coming at me so that’s as close as I got.
