The Island of Dreams 

Samui, a municipality in Surat Thani and Thailand’s second-largest island, sits gracefully in the Gulf of Thailand. Once a quiet fishing community, it has grown into one of the country’s most sought-after island escapes, loved for its coconut groves, jade peaks, and powder-soft beaches fading into turquoise seas. Home to about 67,000 residents, the island is ringed with coral reefs and dotted with waterfalls and sacred temples. Compact enough to explore in a day, Samui still offers endless experiences, from sunrise yoga to lively night markets. Despite its global fame, Samui has kept its soul. Fishermen cast nets at dawn, coconut farmers climb towering palms, and locals welcome visitors with genuine warmth. Beyond the beaches lie jungle trails, healing spas, and a rich food culture shaped by southern flavours and coconut sweetness.
