This excursion is ideal for those who have never tried scuba diving before but want to give it a go. Although the lesson won't get you the full diving certification, it will let you complete a scuba dive on the day :so you'll get the chance to experience the rainbow-coloured corals and fantastic sea life off the Mexican coast. After shimmying into a wetsuit, you'll start off in the pool, learning the basics of diving. Then, you'll move out onto the reef to put theory into practice. You'll be able to dive up to 27 feet, so there's a good chance you'll spot things like turtles and barracuda, as well as Technicolor fish.
