Sairee Beach is the longest beach on the island. Along the beach there are lots of bungalow resorts, restaurants and bars. There are also a lot of small boats transporting divers to the diving boats lying a bit off the beach. The middle of the beach is the most busy stretch and not so nice for swimming, but if you go to the most northern part you will find it very peaceful. Here you can relax under a coconut palm (check that there are no coconuts above you) or you can rent a sun bed with umbrella (the only ones to rent on laid back Koh Tao). This is a very good place for children to play and swim.
