Koh Rok & Koh Haa Snorkel Tour Review 2025 | From Koh Lanta

Honestly, when you’re staying on Koh Lanta, you just get this feeling that the real magic is a little further out at sea. The island itself is, of course, absolutely lovely, but your eyes are kind of always drawn to the horizon. As I was saying, there’s a promise of something more, something a little more untouched waiting out there in the big blue. For the upcoming 2025 season, the sea trip that keeps coming up in conversations is the one that takes you to Koh Rok and Koh Haa. Well, it’s not just a boat ride; it’s more or less talked about as a full-day escape. So, it felt like something we had to look into. Actually, this isn’t about just ticking boxes off a list. To be honest, it’s about that search for a piece of that picture-postcard perfection that you see online and wonder if it’s even real. You know, that crystal-clear water and all those colorful little fish swimming around. We were basically looking for a day that would stick in our memories for a very long time.

So, the thing is that people describe these islands as twin jewels of the Andaman Sea, and that’s a pretty big claim, right? Apparently, Koh Haa is a collection of limestone karsts that create a kind of protected lagoon, and Koh Rok is a duo of islands with sand so white it almost hurts your eyes. Anyway, the idea of a day split between these two spots seemed like a really good plan. It’s almost like you get two very different types of marine experiences in a single outing. You get the dramatic scenery and then you get the perfect beach. This review, at the end of the day, is my attempt to walk you through our entire day, from the very early start to the sleepy ride back to shore. Obviously, I want to give you a genuine feel for what this specific 2025 Snorkel Adventure Sea Tour is all about. Seriously, I’ll cover the little details, the feelings, and what you might really expect if you decide this trip is for you.

The Morning Pick-up and Pier Departure

Okay, so the day started early, as these kinds of trips often do. The pickup from the hotel was, thankfully, pretty much on time. It was one of those open-air style pickup trucks with benches in the back, which is sort of the standard mode of transport on Koh Lanta. As a matter of fact, the morning air was still a little cool and had that damp, tropical smell. You know, the kind of smell that’s a mix of green plants and salty sea. Anyway, the ride to the pier on the eastern side of the island was an adventure in itself. We rattled along roads, seeing parts of the island that you normally wouldn’t, like the local villages just starting their day. To be honest, it’s a nice way to wake up and see the real side of life there.

At the pier, things were, well, already buzzing with a bit of organized commotion. There were a few different tour groups getting ready, so you could really feel the anticipation in the air. We were checked in by our tour leader, a really friendly local guy with a huge smile who, like, immediately made everyone feel welcome. He handed us our snorkeling gear for the day—mask, snorkel, and fins. Honestly, getting your gear at the pier is a good system, because you can check that it fits you properly before you’re even on the boat. He gave a quick briefing about the day, explaining the schedule and some basic safety points. It was all very clear and, you know, not rushed at all, which was pretty nice. It made you feel like you were in good hands, basically.

Then, it was time to get on the boat. For this trip, it was a pretty modern speedboat, with three big engines on the back. You sort of look at it and think, “Okay, we are definitely going to move fast.” Finding a seat wasn’t hard, and there was a choice between sitting inside in the shade or out at the front in the sun. As I was saying, we chose the front for the views, which was a great decision later on. The crew loaded up some big coolers filled with water and soft drinks, which was a reassuring sight. You definitely don’t want to run out of water out there. With everyone on board and a final headcount, the captain fired up the engines with a low rumble. We slowly pulled away from the pier, waving goodbye to the land for a little while. The real adventure was, at last, just beginning.

First Plunge: The Protected Lagoon of Koh Haa

So, the ride out to Koh Haa was exhilarating, to say the least. That speedboat really did fly across the water, which was a lot of fun. The wind was whipping through my hair, and the salty spray was actually very refreshing. From the front of the boat, you just have this incredible, wide-open view of the Andaman Sea. For instance, the water shifts in color from a deep navy blue to a brilliant turquoise as you get further from the mainland. You could see other small, jungle-covered islands dotting the seascape. After about 45 minutes, maybe a bit less, our guide pointed ahead. In the distance, we could just make out a cluster of what looked like jagged rocks rising straight out of the ocean. That, he said, was Koh Haa, which in Thai means “Five Islands.”

As we got closer, the full picture became a lot clearer. These weren’t just rocks; they were limestone karsts, sculpted by wind and water over thousands of years. The five islands were arranged in a sort of semi-circle, creating this amazing, naturally protected area in the middle. The water inside this lagoon was, frankly, a color I’ve rarely seen before. It was this stunning, glowing shade of aquamarine and so unbelievably clear. The boat’s engine cut, and suddenly, everything was quiet except for the gentle sound of water lapping against the hull. The guide explained that this was our first snorkel spot and gave us a few tips on where to find the best marine life. I mean, we were so ready to jump in.

Slipping off the side of the boat into that water was just incredible. The temperature was perfect, like a slightly cool bath. The moment my face went under the water with the mask on, a whole new world opened up. Seriously, it was almost overwhelming at first. The water clarity was so good that you could literally see all the way down to the sandy bottom maybe 15 meters below. The central lagoon area has these amazing coral structures, sort of like underwater mountains and valleys. And the fish! They were everywhere. Bright yellow butterflyfish moved in pairs, and huge schools of shimmering silver snapper swarmed around the coral heads. I spotted a couple of clownfish, you know, like Nemo, peeking out from their anemone homes. The colors were so vivid. There were electric-blue damselfish and parrotfish that were munching noisily on the coral. It was basically like swimming in a perfectly maintained aquarium, only this was very real. We spent a good hour just floating around, completely absorbed by everything there was to see.

Next Stop: The Powdery Sands of Koh Rok

After that amazing first snorkel, it was a little hard to imagine how the day could get any better, to be honest. The crew helped everyone back onto the speedboat, and they were right there with cold drinks and some fresh-cut pineapple, which was a really nice touch. It was exactly what we needed. As we dried off in the sun, the captain started the engines again, and we began the next part of our sea trip, heading south towards Koh Rok. The guide explained that this part of the journey was a bit longer, maybe another 40 minutes or so. By the way, this was a great time to just relax and take in the scenery. The feeling of the sun and the steady motion of the boat was more or less incredibly peaceful.

You know, the Andaman Sea just feels so vast when you are out in the middle of it. We passed by a few local fishing boats, and their crews always gave a friendly wave. Our guide took this time to chat with people, sharing stories about the area and pointing out different landmarks. Anyway, he told us that Koh Rok is actually two islands right next to each other, Koh Rok Nai and Koh Rok Nok. They are part of a protected national park, which is why the nature there is supposed to be so well-preserved. You could feel the anticipation building on the boat as we got closer. Everyone was kind of looking out, trying to be the first one to spot it.

And then, we saw it. First, it’s just a smudge of green on the horizon. But as you get closer, it resolves into these two beautiful islands covered in thick, green jungle. But honestly, the first thing that really captures your attention is the water. The sea around Koh Rok is a completely different shade of blue—it’s a light, almost electric, turquoise that looks almost unreal. And then you see the beach. The boat slowed down as we approached Koh Rok Nai, and we glided into a bay where the beach was a perfect curve of the most brilliant white sand I have ever seen. It seriously looked like powdered sugar. The sand stretched from the jungle’s edge right down into the super clear water. At the end of the day, it was the definition of a tropical paradise, the kind of place you dream about. We had arrived, and it was time for lunch in this absolutely stunning setting.

A Beachside Feast and Relaxation Time

So, the crew anchored the speedboat just a short swim from the shore and brought everything we needed for lunch over on a longtail boat. It was a pretty efficient operation. They set up a few mats in the shade of some large trees right at the edge of the jungle. It was, honestly, the most scenic dining spot you could ask for. While they were getting the food ready, we had a bit of time to just explore the beach. The sand was so fine and soft underfoot, it was amazing. You could just walk into the water, which was shallow and warm, and see little fish darting around your ankles. It felt completely and utterly peaceful.

Now, about the food. I was sort of expecting maybe just some simple sandwiches, but this was a proper feast. The crew laid out a spread of delicious Thai food. There was a big container of Massaman chicken curry, which was rich and flavorful without being too spicy. They also had a large dish of stir-fried vegetables, some steamed jasmine rice, and a plate of fried chicken that was surprisingly crispy. Obviously, everything tasted so much better eaten outside in the fresh air with the sound of the waves in the background. They also had a huge platter of fresh fruit, like watermelon and more pineapple. It was all very well organized and very tasty. Seriously, a much better meal than I anticipated for a boat tour.

After we all had our fill, we had about an hour and a half of free time. This was just perfect. Some people went for a swim in the calm, turquoise bay. A few others, you know, just found a shady spot under a tree and took a little nap. We decided to go for a short walk along the beach. This is when we discovered that the island has some permanent residents: huge monitor lizards. They are pretty used to people and just kind of wander around, minding their own business. It was really cool to see them up close. As I was saying, this downtime was a huge part of what made the day so great. It didn’t feel rushed at all. You had time to eat, relax, and just soak in the incredible natural beauty of Koh Rok. It was a really well-paced part of the day.

Snorkeling in Koh Rok’s Aquatic Garden

After that relaxing break and delicious lunch, it was time for our second big snorkeling session of the day. The guide called everyone back to the speedboat, and we motored just a few hundred meters away from the beach to a spot right between the two islands of Koh Rok. He explained that this channel was known for having some of the most impressive coral formations in the region. The water here seemed even clearer, if that was even possible. From the boat, you could literally see the coral reef systems below the surface. It looked like a vast underwater garden, basically.

Getting back into the water was just as exciting as the first time. The reef at Koh Rok was quite different from what we saw at Koh Haa. It felt more sprawling and intricate, with massive fields of staghorn coral and huge, round brain corals. I mean, the sheer amount of life was just breathtaking. It was a very busy place underwater. Schools of hundreds of fish would move as one, parting around you as you swam through them. The diversity of the coral also meant a wider diversity of fish. I saw several huge titan triggerfish, which are always impressive, and a long, slender cornetfish that was hunting smaller fish.

You know, you could honestly spend hours just floating in one spot, watching the complex little society of the reef play out below you. It’s so absorbing, you pretty much lose track of all time.

One of the absolute highlights of this snorkel spot was finding a moray eel peeking out from a crack in the reef. It was just its head visible, opening and closing its mouth. It was a little bit thrilling, to be honest. Our guide, who was snorkeling with the group, was great at pointing things out that we might have missed on our own. For example, he showed us where a giant clam was embedded in the coral, its iridescent mantle shimmering in the sunlight that filtered through the water. He also pointed out a hawksbill turtle that was swimming gracefully in the distance, which was an absolutely magical sight. At the end of the day, the snorkeling at Koh Rok lived up to all its promises and then some. It was a very rich and vibrant marine world, and getting to swim through it was a real privilege.

Helpful Things to Bring for the Day

Okay, so if you’re planning on doing this trip, there are definitely a few things you should pack to make your day more comfortable and enjoyable. It’s basically a full day out on the water, so being prepared makes a huge difference. I learned a couple of things, and so I want to pass them along to you.

First and foremost, let’s talk about the sun. The Thai sun is no joke, especially when you are on a boat where it reflects off the water. So, reef-safe sunscreen is absolutely a must. Now, you might think any sunscreen is fine, but actually, the regular kind has chemicals that can harm the coral reefs you’re there to see. Most shops in Koh Lanta sell the reef-safe kind, so it’s easy to find. Likewise, a good hat with a wide brim and a reliable pair of sunglasses are your best friends on a trip like this. They just make things so much more comfortable.

Here’s a more or less quick list of other items you should really consider bringing along:

• A Towel: This seems obvious, right? But it’s easy to forget. The tour company doesn’t usually provide them, so definitely bring your own from your hotel.
• Waterproof Bag: A small dry bag is seriously useful for keeping your phone, camera, and wallet safe from splashes on the boat and at the beach. You can pick one up cheaply all over the island.
• Camera or GoPro: You are going to want to take pictures, trust me. An underwater camera like a GoPro is obviously ideal for capturing the snorkeling, but even a phone in a waterproof case will get you some great shots.
• A Change of Clothes: For the ride back, it’s really nice to change out of your wet swimwear and into something dry and comfortable. Just a t-shirt and shorts will do.
• A Small Amount of Cash: While the tour is all-inclusive, it’s a good idea to have a little bit of cash on you. It’s customary to tip the boat crew if you feel they did a great job, and they really do work hard all day.

Is This Snorkel Adventure the Right Choice for You?

At the end of the day, you’re probably wondering if this particular tour is a good fit for you and your travel companions. It’s a fair question, as everyone has different expectations for a day trip. So, let’s break it down a little bit. In my opinion, this tour is honestly fantastic for a pretty wide range of people, but there are a few things to think about.

Basically, if you are a couple or a solo traveler looking for that perfect “escape to paradise” day, then this is absolutely for you. The scenery is romantic, the beaches are stunning, and there is a good balance between guided activity and personal relaxation time. Similarly to that, for families with children who are confident swimmers, this can be an incredible experience. Kids will be amazed by the fish and the boat ride itself is an adventure. The guides on our trip were really good with the children on board, making sure their masks fit and pointing out “Nemo” fish. However, for families with very young toddlers, you might want to consider that it’s a very long day out and the speedboat can be quite bumpy, which might not be comfortable for them.

You don’t need to be a professional snorkeler to enjoy this. As a matter of fact, it’s great for beginners. The crew provides life jackets for anyone who wants one, which allows you to just float on the surface comfortably without having to tread water. They give clear instructions, and the chosen snorkel spots, especially the lagoon at Koh Haa, are generally calm and protected. Still, you should be comfortable in open water. If you have a serious fear of the sea, this might be a bit much. The only other thing to think about is the physical nature of the trip. You’ll be climbing in and out of the boat and the speedboat ride can get bumpy if the sea is a bit choppy. So, if you have serious back or mobility problems, this specific type of tour might be a bit of a challenge.
