Morning Light and Coral Gardens: A Day Snorkeling Mu Ko Rang from Ko Kut
Half a day of reef gardens, local crews, and clear-water snorkeling off Ko Kut
You climb down a low ladder on a wooden boat as the first light slices across the Gulf of Thailand. The engine ticks to a steady rhythm and the island silhouettes of Mu Ko Rang National Park draw nearer—rounded granite shoulders rising out of glassy water. A breeze tastes faintly of salt and lemongrass from the island kitchens you left behind on Ko Kut. The guide passes out masks and fins, demonstrates clearing a snorkel, and then points to a ridge of coral framing a shallow bay. When you slip into the water the world changes: sunlight filters through warm water, a tapestry of parrotfish, butterflyfish, and sprawling hard corals answers your curiosity.
Trail Wisdom
Arrive early
Get to the pier 30 minutes before departure for check-in and a calm gearing-up period; morning light also equals the best underwater visibility.
Use reef-safe sunscreen
Apply before boarding and reapply with a mineral-based product to protect coral and reduce wash-off in the water.
Bring a dry bag
Protect your valuables and change of clothes from spray and sun; small 5–10L bags work well.
Float smart
Keep a relaxed horizontal position and kick gently to avoid accidental contact with coral; ask the guide for advice on currents.
