Khao Lak: Full-Day Snorkeling in the Similan Islands – A Honest Look
Planning a day of snorkeling in Thailand’s famous Similan Islands from Khao Lak? This tour promises a full day of marine adventure, picturesque beaches, and tasty Thai food. But as with many popular excursions, it comes with its share of highs and lows, especially given the reviews pointing to crowded spots and some uneven experiences.
What we love about this tour? First, the chance to explore some of Thailand’s best snorkeling sites—with clear waters, vibrant fish, and untouched coral reefs. Second, the opportunity to relax on stunning white sand beaches, far from the chaos of daily life. Third, the authentic Thai lunch at Princess Bay Beach, a great way to fuel up after a morning in the water.
However, a major consideration is the crowd factor. Many reviews mention large groups and multiple boats at the same spots, which can detract from the feeling of discovering secret, untouched places. This experience is best suited for travelers who are happy to share popular sites and are looking for an affordable, all-in-one day trip rather than a secluded escape.

What to Expect from the Full-Day Snorkeling Tour

Here are more experiences we've reviewed in Khao Lak
Early Morning Pickup and Transport

You’ll be picked up from your hotel in the Khao Lak area, with departure times starting as early as 6:50 AM from some locations. The journey to the Similan Islands is by speedboat, which offers a faster and more exciting ride compared to larger, slower vessels. Expect the ride to be lively, with some reviews mentioning the boat being cramped with about 60 others, especially during busy seasons.
The convenience of hotel pickup is a big plus, removing the hassle of logistics. However, if you’re staying in Phuket, this trip isn’t an option, so be prepared for the drive to Khao Lak.
The Maritime Experience and Snorkeling Stops

Once at the islands—specifically at island number 4—your main activity begins: snorkeling in some of Thailand’s top spots. The waters here are renowned for their vibrant marine life and coral formations, which you’ll get to explore with the aid of provided gear.
Reviewers have pointed out that the marine life is plentiful, with sightings of parrot fish, sea turtles, and even sea snakes. Yet, several comments mention the crowds at these sites—more than 70 people often share the water, which can make it feel less like a hidden paradise and more like a mass swim.
The stops at islands 9 and 8 follow around midday, giving you further opportunities to snorkel and enjoy the scenery. The guide’s commentary, typically in English and Thai, helps identify the marine species and makes the experience engaging, especially if you have a knowledgeable guide like those mentioned in reviews.
Lunch at Princess Bay Beach

A highlight for many is the Thai lunch served around midday. While some reviewers found the food to be “not really enjoyable,” others appreciated the chance to try local flavors in a stunning setting. The meal is a simple affair, often described as decent but not gourmet—more a practical fuel-up than a culinary highlight. Expect to see some fresh fruits, rice, and perhaps grilled fish, though opinions vary.

After the last snorkeling stop, you’ll head back to Khao Lak in the early afternoon, arriving around 4 PM or so. The ride back can be a bit tiring, especially after a long day in the sun, but the memories of underwater encounters and scenic beaches tend to linger.

– The guides are generally knowledgeable, helping you spot marine life and explaining the surroundings.

The Value of This Tour for Different Travelers

If you’re after a cost-effective way to see multiple snorkeling sites in a day, this trip delivers. It’s perfect for those who don’t mind sharing popular locations with large groups and are primarily interested in the marine life and beaches rather than privacy.
For travelers who value quiet, untouched spots, this might not be the best fit, given the consistent mentions of crowds. Those who enjoy guided tours with local insight will find the guides helpful, though some reviews suggest the experience could be improved with smaller groups or more personalized service.
The inclusion of hotel pickup and drop-off simplifies logistics, making it more accessible for busy travelers or those unfamiliar with local transport options. However, the long day—up to 10 hours—means you’ll want to be prepared for early mornings and a full day in the sun.
Practical Tips for a Smoother Experience

- Bring essentials: Sunglasses, sun hat, towel, waterproof camera, and sunscreen are must-haves.
- Arrive early: Even with scheduled pickup times, arriving promptly ensures you won’t miss the boat’s departure.
- Prepare for crowds: If you prefer less crowded environments, consider visiting during off-peak seasons or seeking smaller tour operators.
- Snorkeling gear: Usually provided, but check beforehand if you want to bring your own for comfort.
- Weather considerations: The itinerary might change due to weather, so stay flexible and keep an eye on updates from the tour operator.
- Passport photocopy: Needed if you wish to purchase a Similan island entry ticket, plus it’s a good idea to carry your original for identification.
