KOH SAMUI


Ever since The White Lotus transported us into the world of decadent island resorts, sun-drenched terraces, and drama-filled infinity pools, luxury travel has taken on a new allure. While the series has hopped from Hawaii to Sicily, now, with season three being filmed at the Four Seasons Resort Koh Samui, Thailand’s most glamorous island is about to have its moment in the spotlight. Koh Samui is an island paradise where luxury isn’t just about extravagance, but about seamlessly blending indulgence with natural beauty.
