The scooter snorkels are easy to use and very handy as we ended up swimming for like 2 hours! It was absolutely amazing, we saw 3 turtles, at least 2 stingrays and so many beautiful fish! Our guide had an underwater camera and took pictures of us swimming with turtles and of beautiful marine life that we couldn't see close us because we didn't know how to dive down as well as he did!
He gave us all the photos via Dropbox, all included in the price. There happened to be no one else on the tour with us that day so he took us hiking beneath the Pillars of Hercules as well, which was blissful. although I would recommend water shoes and a bit of courage to jump over rocks!
