Exploring Hong Island
The island’s calm waters and vibrant coral reefs make snorkeling an engaging activity, though some reviews suggest water clarity might vary. As one traveler noted, water clarity was “poor” and the fish count limited at the first snorkeling spot, but the experience of floating in warm waters and seeing what marine life is present still brings value.
We appreciated the way the guides make this accessible—providing snorkeling masks and life jackets—and the opportunity to just relax on the beach or swim in the lagoon. The scenery is memorable: limestone cliffs framing emerald waters create that classic tropical Thai island look.
The Scenic Lagoon and the Climb
Cruising through a narrow opening into Hong Lagoon, you’ll see lush limestone walls and shimmering water. It’s a picture-perfect moment, especially if you’re into photography. The guides are good at pointing out interesting features and helping you capture the scenery.
For those who enjoy heights, the climb up to the viewpoint is well worth the effort. The view offers a stunning, broad perspective over the islands and sea, giving you a real sense of place. One reviewer described it as “worth the short climb,” and others appreciated the chance to get some good photos.
Sunset and Dinner at Pakbia Island
Later, the tour moves to Koh Pakbia for a sunset viewing. Here, you’ll enjoy a Thai-style buffet dinner on the beach. The meal is described as both generous and tasty, with options accommodating dietary needs (vegetarian, vegan, halal). The sunset views are often praised, with reports of atmospheric musical accompaniments adding to the mood.

The tour’s pièce de résistance is night swimming with bioluminescent plankton at Koh Raeng. This is an experience that truly feels otherworldly. As you dip into the water, tiny glowing organisms light up around you, creating a magical, starry effect beneath the waves. Several reviews highlight how special and memorable this part of the trip is, making it worth the price alone for many travelers.
Keep in mind, the bio plankton activity is weather-dependent and occurs only when sea conditions allow. Some travelers mention that the water clarity can vary; still, the glow of the plankton often compensates for less-than-ideal conditions.
What to Expect: The Day in Detail
The trip begins with a pickup between 12:00 and 13:00 from your hotel, covering most accommodation areas around Ao Nang, Krabi Town, and nearby beaches. The longtail boat ride to Hong Island is a scenic highlight, giving you your first glimpses of the limestone formations that make this area so iconic.
On Hong Island, you’ll find plenty of options for relaxing or active pursuits. The beach offers good space for sunbathing or swimming, while the climb to the viewpoint is short but steep—worthy if you’re up for a little exertion and panoramic views.
The cruise through Hong Lagoon offers scenic photos, with limestone cliffs and emerald-green water. This is a quieter, more intimate experience away from crowded tourist spots, which many reviewers find appealing.
The dinner at Koh Pakbia is a leisurely affair, with the sunset providing a spectacular backdrop. The buffet is described as “very good,” and the atmospheric setting makes it a relaxing break from the day’s more energetic activities.
The final act is the night snorkeling with bioluminescent plankton. You’ll likely need to gear up with masks and life jackets, then dip into the dark waters to witness this natural light show. Despite some reviews noting water clarity issues, the glow itself tends to be consistently impressive.
