If scuba isn’t your thing but you love the simplicity of snorkelling then free diving might just be for you. Free diving or breath-hold diving had been around for eons — it existed long, long before scuba. Traditionally it was a way of collecting sponge and fishing, but free diving has evolved into a competition sport and an alternative to scuba for exploring the underwater world. Being a major centre of underwater exploration, naturally you can learn to free dive on Ko Tao.
