The Thai islands are hard to beat for scenery: jungle-covered peaks soften to white sandy beaches, which are lapped by the sapphire waters of the surrounding seas. But if that wasn't enough, they are also home to some of the world's most exclusive resorts, which promise first-class service, and unparalleled luxury on your tropical island escape. In the Gulf of Thailand lay Koh Pha-Ngan and Koh Tao. The former is a heavenly island known for its gorgeous beaches, and vibrant Full Moon Parties that take place each month, whilst the latter is an internationally renowned dive resort, where you can delve beneath the surface of the water to discover vibrant coral reefs rich with colourful marine life. If you're looking for seclusion, then visit Koh Kood, also in the Gulf of Thailand, and a bit of a hidden gem. Head west to the Andaman Sea, and you’ll find the islands of Koh Phi Phi and Koh Lanta. Located just a short boat ride from Phuket, the Phi Phi Islands are some of the loveliest in Thailand. Admire the stunning rock formations that rise from tranquil waters, snorkel the translucent waters, or visit Maya Bay where the movie The Beach was filmed. Nearby Koh Lanta, protected by Mu Ko Lanta National Park, features beautiful mangroves, vibrant coral reefs, and dense rainforests.
