Located in the Andaman Sea, halfway between Phuket and Krabi, sits the one of Thailand's last untouched islands - Koh Yao Yai. A true paradise of spectacular beaches, rubber & coconut plantations, picturesque sunsets and amazing sea life. Here you can experience the slow life of islanders. The top spot here is Lam Haed beach, especially by drone during high tide. For accomodation, I recommend Santhiya Koh Yao Yai resort with their private pool villas (check their website, they often have 50% discount) or Braya Villa on Airbnb.
