Ko Tao is an island in the Gulf of Thailand. The island is best known for scuba diving and snorkelling, hiking, rock climbing, and bouldering. The white sandy beach of 1.7 km interrupted only by a few huge boulders with budget-friendly resorts around. Home to great many granite boulders, both in the forests and on the beaches of Ko Tao, attract a growing number of climbers.

Ko Tao is less developed than Ko Samui and Ko Pha-ngan, but has become increasingly popular especially with the mid-20s backpacker crowd in search of relatively inexpensive scuba diving certification. For the past two years, the demographics of the island have seen an age increase, with many of the visitors who first visited the island over ten years ago now returning with their families.
