Highly recommended. It was very easy to pick up, thanks to Nacho and Ana's instructions; they put your safety above everything, so you know you're in good hands. I was able to "fly" underwater, do twists and tricks, all the while exploring under the sea . We saw a couple of turtles, and many starfish; It was beautiful!
I'd recommend this activity for groups, bring a surf shirt or really tight swimming suit, definitely bring a GoPro!
