A whole new world awaits the traveller under the sea. Here's your guide to diving in and making the most of it...
Diving and snorkelling immerses you into a floaty, contemplative world filled with mystery and colour – and often heaving with quirky marine life.
Snorkelling is an easy first step to take towards under-water diving. It is best enjoyed with at least one ‘buddy’, although it doesn’t have to be limited to just one other person – whole families can snorkel together.
Once confident snorkellers, many people want to learn to dive. One popular way to become proficient is on a specialised learn-to-dive holiday. Wherever land meets sea, you will find a diving school, which can train you to a high level of competency. Organisations such as the Professional Association of Diving Instructors (PADI), Scuba Schools International (SSI), and The British Sub Aqua Club (BSAC) have training schools teaching diving fundamentals.
A whole new world awaits. Dive in and discover it.
