Koh Ta Kiev is the widely-ignored (at least by travellers) little brother of the island group -- it is also considerably closer to the mainland than the others. The island is home to three lovely yellow-sand beaches shaded by pine trees are accessible on the island, and coral reefs make for excellent snorkelling. Long Beach hosts most of the accommodation, with Coral Beach at the southernmost, tucked in on its own secluded bay. It's possible to walk the entire stretch and the pine needles make this long sandy stretch of sand seem less ‘pure' than it might otherwise feel.
Trekking paths meander through Koh Ta Kiev's jungle if you're feeling adventurous and would like to do a bit of wildlife-spotting and bird watchers will be happy to hear that more than 150 species call Koh Ta Kiev home. One path is identified by blue markers which takes you to the local fishing village on the east side, another by red markers which heads south from the centre of the island, leading you to Naked Beach on the south of the island.
