Sairee Beach located in the west of the island is the largest and most popular beach stretch in Koh Tao. Access is very easy and restaurants, resorts, bars, and dive shops line the entire waterfront. Many holiday makers are sunbathing, playing beach volleyball, kayaking, dining and enjoying the social and lively atmosphere. The sand is soft and the water clear, but one must swim out quite a distance to experience some good snorkeling activity. Sairee beach also is largely affected by the tide. At times it seems like the sand stretches out forever, whereas other times it doesn't leave much space on the beach for lounging. The water is mostly still and shallow and is great for families with young children.
In the evening Sairee beach becomes a magical place with the breathtaking sunsets. Many visitors and locals alike enjoy a happy hour evening drink while staring out at the magnificent colours of the sky. Restaurants and bars come to life with fun music and the later it gets, the wilder the beach party can become. Even if one is not staying in Sairee during their holiday, it would be hard to miss this 1.5 km beach stretch with sunsets that need to be seen to be believed.
