In January 2020 I traveled to Hopkins, Belize to provide formal Free Dive training to a pod of local spearfisherman/freedivers.

It takes a boat ride to get out to the reef, but it is one of the most spectacular underwater environments in the world. She sheer scale of the barrier reef, right there on the edge of very very deep blue water, is as awe-inspiring as it is rich with underwater life.
The weather was unusually rough while I was there yet, even with sometimes extremely large waves, the visibility was over 100 feet.

Another highlight for me was a small blue hole the local guys had discovered. None of them wanted to go in it so, naturally, I had to :) It was extremely creepy because it went from being a hole about 30 feet across at 35 feet to a relatively narrow crevice at about 70 feet, then another one at 90. The lighting was such that you couldn't see what was beyond each crevice until you were in it. Really fun, and a nearly perfect place for training.
