If you’re captivated by the underwater world and dream of exploring vibrant coral reefs teeming with life, I’ve got the perfect adventure for you. Nestled in southern Thailand, on the tranquil island of Koh Lanta, lies one of the best snorkeling tours in the region—a full-day trip that’s nothing short of spectacular.

Why Koh Lanta is a Must-Visit

First, let’s talk about Koh Lanta itself. This island is the epitome of relaxation, offering a peaceful retreat away from the bustling tourist hubs of southern Thailand. Unlike its lively neighbors, such as Koh Phi Phi or Ao Nang, Koh Lanta has a calm and laid-back vibe. Spend a few days here, and you’ll fall in love with its uncrowded beaches, delicious food, and wide range of accommodations to suit all budgets.

During my visit, I stayed four nights at AHA Hostel, one of the nicest hostels I’ve ever experienced. It’s modern, clean, and offers a social atmosphere perfect for solo travelers. I then spent another four nights at C Lanta Hostel, a beachfront gem with a pool overlooking the ocean—ideal for relaxing after a long day of exploring. Whether you’re a backpacker or prefer the comfort of a resort or an Airbnb, Koh Lanta has options for everyone.

While wandering around, I discovered a variety of activities, from cooking classes to fishing trips, but it was the snorkeling tour that caught my attention. The 2-Island Snorkeling Tour came highly recommended by locals and fellow travelers alike, and it did not disappoint. After three trips to Thailand, I can confidently say this was the best snorkeling experience I’ve had so far.

Booking the Tour

We booked with Pattesia Speed Boat Tours, which cost 1,000 Thai Baht per person (about $28 USD), plus a 400 Baht national park fee. For that price, we got round-trip transfers from our hostel, snorkel gear, lunch, drinking water, and a guide. The entire day was seamless and stress-free, from the moment we were picked up to the moment we were dropped off at our hostel. The ease of the day made it even more enjoyable—no need to worry about transportation, logistics, or equipment.

The Day Begins

Our day started bright and early at 8:00 AM, with a tuk-tuk picking us up from our hostel. The short 25-minute ride to the port gave us a glimpse of Koh Lanta’s scenic roads lined with lush greenery and quaint local villages. At the port, we checked in, paid the national park fees, grabbed a coffee, and boarded our speedboat.

The boat ride itself was breathtaking. The calm, turquoise waters reflected the morning sun, and as we approached our first destination, Koh Rok, we were greeted by towering limestone cliffs and pristine white sand beaches. These dramatic rock formations are a signature feature of southern Thailand and create a stunning backdrop for the crystal-clear waters.

Our first snorkeling spot at Koh Rok was nothing short of magical. The water here is so clear that you can see straight to the bottom, even from the boat. When we jumped in, we were immediately surrounded by schools of colorful fish, including clownfish darting between anemones, bright parrotfish, and sleek needlefish gliding near the surface.

The tranquility of this spot was unmatched. Unlike busier snorkeling destinations in Thailand, this area felt untouched, with only a handful of other boats nearby. The absence of crowds allowed us to fully immerse ourselves in the experience, swimming freely and marveling at the vibrant coral reefs below.
