Exploring the Itinerary in Detail

The tour kicks off around noon, with pickup from your hotel in Krabi or Ao Nang, then a short transfer to Nopparat Thara Pier where you board a big longtail boat. A key detail here is that the group size is capped at 30, which helps keep the experience manageable, but some reviews mention the boat can feel cramped, especially when full.

Stop 1: Ko Ya Wa Sam

Your first stop is Ko Ya Wa Sam, famed for its vibrant coral reefs and marine life. Here, snorkel gear is provided, and many reviewers highlight how “snorkeling with colorful marine animals” was a highlight. It’s a solid introduction to the underwater world of Krabi, though visibility might vary—some guests note that currents can make the water a bit murky. The hour-long stay allows enough time to dip in and out without feeling rushed.

Stop 2: Chicken Island

Next, it’s time for Chicken Island, a favorite for its distinctive rock formation resembling a chicken’s head. Snorkeling here is described as good, with plentiful marine life and coral reefs. Reviewers appreciated the “abundance of marine life,” making it a worthwhile stop, though some found the crowds a little overwhelming. The included snorkeling gear helps you explore comfortably.

Stop 3: Tup Island

Tup Island is famous for its sandbar connection to two neighboring islands during low tide. You’ll love the photos and the feeling of walking across the sandbank—perfect for a quick stroll and some memorable snapshots. Reviewers describe Tup Island as “a popular tourist destination” and one of Thailand’s unseen highlights. The water here is calm, making it an ideal spot for relaxing and wading.

Stop 4: Ko Mor

This is the sandbank connecting Chicken Island and Tup Island, offering a chance to walk on natural formations. It’s a short stop, but many mention how fun it is to stand between two islands or even take a quick photo with the water swirling underneath.

Stop 5: Ko Ma Tang Ming

A quick 30-minute snorkeling and swimming session here offers another peek into underwater life. While some reviewers say visibility can be inconsistent, the general consensus is that it’s a decent spot for a short swim.

Stop 6: Poda Island

This is the longest stop on the itinerary—about two hours—and one of the most relaxing. Reviewers love the clear waters and beautiful scenery, making Poda Island perfect for sunbathing, swimming, or just soaking in the views. It’s a good chance to unwind after a busy morning of island hopping, with plenty of space for beach lounging.

Stop 7: Koh Rang Beach & Bioluminescent Plankton

As darkness falls, the tour heads back towards the last highlight: bioluminescent plankton. This part of the tour has received mixed reviews. Some describe it as “like swimming in stars”—a surreal and unforgettable experience—while others found the glow less vivid than internet photos suggest. The tour description notes that the plankton glow as tiny white flashes, which can be quite mesmerizing, especially if you’re prepared for a short, gentle swim.

What’s Included and What’s Not

The tour offers a lot for the price—around $38 per person—which is quite reasonable considering the seven island stops, snorkeling gear, buffet dinner, and transfers. The guides are noted to be attentive and knowledgeable, and safety equipment like life jackets is provided, adding peace of mind.

The buffet dinner at sunset is generally well-rated, with many reviewers describing it as “delicious” and “filling”. Expect a mix of Thai snacks, seasonal fruits, and a barbecue buffet, often served while watching the sunset—a lovely way to end the day.

However, there are additional costs to keep in mind: 200 THB per adult for the national park fee, payable at entry, and a 100 THB extra transfer fee for those staying in Klong Muang or Tub Kaek.

Transportation

Round-trip transfers are included, which is a big plus, especially since some reviews mention initial delays and waiting times. If you stay at certain hotels like Centara Grand Beach Resort, you’ll need to take a shuttle boat to the pier. The transport is generally efficient but can sometimes be delayed, so a bit of patience is required.

Group Size and Comfort

The tour is capped at 30 travelers, which helps keep the experience manageable. Still, some reviews mention the boat feeling cramped or crowded. The boat’s ladder can also be a challenge for some—getting in and out can feel awkward, and a couple of reviewers had minor injuries due to unstable steps.

The Experience: What You’ll Love and What to Watch For

Highlights That Shine

The scenic island stops are the core of this tour. From the colorful reefs at Ko Ya Wa Sam to the iconic sandbar at Tup Island, you’ll get plenty of chances to swim, snorkel, and snap photos. Many reviews praise the guides’ helpfulness, especially on the snorkeling sections, where they often show which jellyfish pose no threat and how to avoid touching coral.

Sunset dinner stands out as a memorable moment, with many guests describing the views and food positively. The bioluminescent plankton at night, despite some variability, offers a rare opportunity to witness nature’s light show, with many describing it as “swimming in stars” or feeling like being in outer space.

Considerations and Drawbacks

The crowded boats and quick island visits can limit how much time you spend relaxing or exploring each stop thoroughly. Some reviewers mention feeling rushed—20 minutes at the first island, for example—so if you prefer longer, more leisurely visits, this might not fully satisfy.

The snorkeling visibility can be inconsistent, and some stops may not feature as much marine life as hoped. The boat ladder has caused minor injuries for some guests, and the boat’s overall comfort varies depending on how full it is.

The bioluminescence is a highlight but can be underwhelming if weather conditions aren’t ideal, such as recent rain reducing the glow. Plus, some travelers expected a more vivid light display based on internet photos, but that’s not always what you’ll see.

Food and Beverage

The included buffet dinner is generally described as “tasty” and “filling”, with some reviewers mentioning the BBQ as a highlight. Drinks like soft drinks, water, and Thai snacks are included, making it easy to stay refreshed.

Value for Money

Considering the length of the tour, the number of stops, snorkeling gear, meals, and transfers, $38 per person is a reasonable price. Many reviewers feel it offers good value, especially given the variety of experiences packed into one day. However, if you’re seeking a more relaxed or exclusive trip, you might find the crowding and quick stops less satisfying.

Who Is This Tour Best For?

This trip is perfect for adventure-seeking travelers who enjoy being on the water, snorkeling, and exploring multiple islands in a single day. It’s a good fit for families, groups of friends, or solo travelers comfortable with sharing a boat and dealing with some hustle and bustle.

If you’re after serene, in-depth reef exploration or luxury comfort, this might not be ideal. But if you want a fun, active day with stunning views, diverse island stops, and the chance to see bioluminescent plankton, this tour hits the mark.
