This tour offers a beautifully balanced mix of natural beauty, adventure, and a touch of magic, all wrapped into a single day. For just $62, you’ll visit Hong Island’s secret lagoons, enjoy a sunset buffet on Pakbia Island, and witness the fascinating glow of bioluminescent plankton at Koh Raeng.

The Itinerary and Its Magic
The tour kicks off with a midday hotel pickup, which means you avoid the early-morning rush and can relax into the day. After a smooth transfer to Nopparat Thara Pier, there’s a brief health check—standard procedure—and then it’s off on a traditional longtail boat. This mode of transport instantly connects you to the local vibe—no glitzy speedboats here, just a traditional Thai vessel that adds to the adventure’s charm.
Hong Island, the main highlight, is famous for its secluded lagoons and towering limestone cliffs. We loved the way the guide explained the geography of these islands—each one a different piece of nature’s artwork. Cruising into the Hong Lagoon is a highlight, with its emerald waters and dramatic cliffs perfect for snapping photos. The viewpoint atop Hong Island offers a 360° panorama of the surrounding islands, including clear waters and lush greenery—an essential stop for breathtaking views.
Snorkeling at Koh Hong is another standout. The waters are filled with colorful tropical fish, and the coral formations are vibrant—perfect for both beginners and more seasoned snorkelers. The shallow lagoons make for safe, relaxing swims, and you’ll have plenty of time to soak up the idyllic scenery.
Next, we head to Pakbia Island, where a buffet dinner awaits on a quiet beach. The setting sun creates a beautiful backdrop as you enjoy local dishes and vegetarian options, making it an ideal spot to unwind. The food quality and the tranquil atmosphere make this meal a memorable part of the day.
As evening falls, the real magic begins. You’ll transfer to Koh Raeng for the night snorkeling experience. Here, the water lights up with bioluminescent plankton—a phenomenon that makes you feel like you’re swimming in a galaxy of stars. The guides are attentive, ensuring safety while you marvel at the glowing water, a truly surreal moment.

It includes hotel transfers, snorkeling equipment, a buffet dinner, and a professional guide, which all add to the convenience.

The seasonal aspect of bioluminescence is worth noting—check with the operator or your guide about the best time to visit if this glow is a must-see for you. The tour’s structure also supports those who want to avoid overly strenuous activities, with manageable walks and easy water access.
