With its white sands, turquoise waters, and palm trees swaying in the breeze, Ko Lanta is the poster child for Thai island paradise. Even though it has been rising in popularity, Ko Lanta still isn’t as developed or well-known as Andaman Sea staples such as Phuket, Krabi, and Ko Phi Phi. And while you’ll want to spend most of your time by the sea, things to do on Ko Lanta aren’t just limited to the beach. You can kayak to uninhabited islands and the Emerald Cave (Tham Morakot), go scuba diving in Mu Ko Lanta National Park, and shop for street food and artisan souvenirs in Ko Lanta’s Old Town.
