Ko Chang Noi and Chang Noi Peninsular, Trat

Ko Chang Noi offers a refreshing contrast to its famous big sister, Ko Chang, with pristine waters and untouched coral reefs that remain largely unexplored by mass tourism. This smaller island sits just off the eastern coast of Ko Chang, close enough for a comfortable day trip yet worlds away from the crowds. The Chang Noi Peninsula extends from the main island, creating sheltered bays and rocky outcrops perfect for snorkeling adventures.

Crystal-clear waters reveal vibrant coral gardens teeming with tropical fish, making this one of Trat’s premier snorkeling destinations. You’ll spot parrotfish, angelfish, and schools of yellowtail snappers darting between brain corals and sea fans. Rocky shorelines provide excellent vantage points for spotting sea eagles and kingfishers, while the gentle lapping of waves against limestone cliffs creates a natural soundtrack. Small sandy coves offer perfect spots for picnicking, with coconut palms providing natural shade. The shallow reefs make snorkeling accessible for beginners, though the outer edges drop into deeper waters where larger fish congregate.

Tranquility defines the experience here, with only the sounds of waves, seabirds, and rustling palm fronds breaking the silence. Unlike the bustling beaches of main Ko Chang, this feels like stepping into a private sanctuary where time moves slower. The absence of permanent development means you’ll share the space primarily with day-trippers and local fishermen, creating an intimate connection with Thailand’s coastal wilderness that’s increasingly rare.

Reach Ko Chang Noi by hiring a longtail boat from Bang Bao pier on Ko Chang – the journey takes about 20 minutes across calm waters. Since no accommodation exists on the island, plan for a day trip with an early morning departure. Bring snorkeling gear, sun protection, plenty of water, and a picnic lunch. The best conditions occur during the dry season when seas are calmest and visibility is optimal for underwater exploration.
