From Phi Phi: Sunset & Bioluminescent Plankton Snorkel Tour

A five-hour adventure starting from the lively Tonsai Pier, this tour takes you around some of the most iconic spots of Phi Phi Island, ending under the stars with a glow-in-the-dark surprise. For just $30 per person, you get a mix of sightseeing, snorkeling, and a rare chance to swim among glowing plankton—an experience that promises both beauty and a touch of magic.

An In-Depth Look at the Experience

The tour kicks off at Tonsai Pier, a buzzing hub of activity and a familiar starting point for many Phi Phi adventures. The meeting is straightforward—just a short walk from the pier, at the McDonald’s, making it easy to find even if you’re not familiar with the area. The boat you’ll ride on is a traditional longtail, which adds to the charm and rustic feel of the journey.

The Stops on the Route

Monkey Beach is your first stop. Here, you’ll see a troop of macaques in their natural habitat. We loved the chance to observe wildlife up close, and it’s a fun break from the boat ride. However, some reviews hint at disorganization, with friends being separated and put on different boats—so if you’re traveling in a big group, keep close and communicate clearly.

Next, you’ll visit Viking Cave, a site of historical cave paintings and swift nests. It’s a quick, fascinating stop, especially if you’re interested in local legends and history. The cave is off-limits for entry, but the view from the boat gives you a sense of the area’s cultural depth.

Pi Leh Lagoon is a highlight for snorkelers. Enclosed by limestone cliffs, this lagoon offers calm waters and vibrant coral reefs. We loved how clear and colorful the underwater life was—perfect for both beginners and seasoned snorkelers. This stop provides a chance to see tropical fish and underwater formations that are truly picture-worthy.

The tour then heads to Loh Samah Bay, another beautiful snorkeling spot. Here, you can relax, take a swim, or snorkel in the invigorating water. The scenery is spectacular—towering limestone cliffs and calm, inviting waters.

Sunset and After Dark

As the sun begins to set—bright hues of orange and pink—the boat slows, giving everyone a chance to appreciate the spectacular view. We enjoyed the fresh fruit served on board, which complemented the cooling sea breeze and the changing sky. The peaceful moment of watching the sunset over Phi Phi’s rugged silhouette is genuinely memorable.

When night falls, the real magic begins. The guide leads the group into the water for the bioluminescent plankton swim. If you’ve never experienced glowing waters, this is a surreal highlight. The tiny organisms light up with every movement, creating the illusion of swimming through a starry night. It’s an experience that rivals the beauty of the night sky itself—not only fun but also a reminder of how vibrant and alive nature can be.

Practical Details

The entire journey lasts about five hours, with starting times available depending on the day. The cost of $30 includes the boat ride, life jackets, snorkeling masks, a guide, fruit, and water. However, a national park fee of 400 THB for adults (200 THB for children) is not included, so budget accordingly.

The meeting point is conveniently located at McDonald’s near Ao Ton Sai Pier, making it accessible for most travelers. The tour is conducted in English and Thai, and guides are generally friendly and helpful, although some reviews suggest the experience can suffer from disorganization.

Who Would Love This Tour?

If you’re after a cost-effective way to see multiple highlights of Phi Phi—from wildlife and caves to stunning snorkeling spots—this trip offers plenty. The sunset and glowing plankton experience are unique features that can make your visit truly memorable. It’s especially suitable if you’re okay with some unpredictability in the schedule and don’t mind a slightly rushed pace.

A Balanced View: The Good and the Not-So-Good

The value for money here is clear. For just $30, you get a well-rounded day of sightseeing, snorkeling, and a magical night swim. The stops are thoughtfully chosen, and the scenery is genuinely breathtaking. We appreciated the chance to combine multiple attractions into one trip, saving money and time while experiencing the best of Phi Phi’s natural beauty.

However, the organizational issues can’t be ignored. One reviewer said, “It was completely disorganised with our friends getting separated and put on to another boat, it was 40 minutes late leaving due to the lack of organisation & rushed every bay.” This suggests that if punctuality and smooth operations are your priorities, you might find this tour frustrating.

Another thing to consider is the duration—at five hours, it’s a full but not overly long outing. Those expecting a leisurely pace might find the quick stops slightly rushed, but most will agree that the highlights are worth it.

The bioluminescent swim stands out as a rare treat, especially since many travelers find it to be a highlight worth the price of admission. The scenic sunset views and the chance to observe local wildlife also add authentic touches to the experience.

If you prefer perfectly organized trips with tight schedules, you might want to explore other options, but if you’re comfortable with some flexibility and love the idea of swimming under a starry, glowing sky, this tour fits the bill. It can be a highlight of your trip, especially if you’re eager to experience the natural wonder of bioluminescent waters in a setting of stunning limestone landscapes and lively islands.
