Travelers seeking a tailored, stress-free day exploring Koh Samui’s Southern Islands often look for experiences that combine comfort, exclusivity, and authentic local charm. A private boat tour offers just that, and the Full Day Private Charter to the Southern Islands is a standout option. Whether you’re celebrating a special occasion or simply craving a day away from crowds, this tour promises a personalized adventure that puts you in control of your itinerary.
We’re impressed by the attention to detail, the flexibility of stopping at multiple islands, and the chance to enjoy stunning beaches and vibrant marine life. The fact that everything is private means your group can enjoy the day exactly as you wish—no fighting for space or adhering to strict schedules. However, the price tag of around $3,360 for up to 10 guests may seem steep at first glance, so understanding the value and what you get is essential.
This experience is ideal for groups or families wanting a customized day on the water, with options for snorkeling, fishing, and relaxing on unspoiled beaches. If you prefer structured tours with fixed schedules, this might not be your best fit, but for those craving freedom and exclusivity, it hits the mark.

An Inside Look at the Full Day Private Charter Experience

Here are more experiences we've reviewed in Koh Samui
Setting the Scene: Starting from Koh Samui
Your journey begins at the Ko Samui Naval Support Base in Lipa Noi, a peaceful spot that makes for an easy departure. The tour runs from 10:30 AM to 6:30 PM—perfect for a leisurely, no-rush day. The boat, operated by Samui Buddy, is a luxurious private vessel that can comfortably host up to 10 guests, ensuring plenty of space for everyone to relax.
The Five Islands: A Unique Cluster
The core feature of this trip is sailing among the so-called Five Islands, which are known in Thai as Koh Si Koh Ha. Interestingly, the name translates to Four Islands, Five Islands because one island is often hidden behind another, depending on your viewpoint. These islands are famous not only for their scenic beauty but also for their bird populations—thousands of nests built in the rocks, which are harvested in traditional, risky climbs.
One of these islands, Koh Madsum, offers pristine beaches with soft white sands and calm waters, ideal for sunbathing or wading into the shallow waters with snorkel gear. The tour guide will likely share stories about the nests and their controversial journey from bird’s nests to gourmet dishes in Hong Kong and China, adding an intriguing cultural layer to your trip.
Koh Tan: The Marine Wonder
Next, you’ll head to Koh Tan, described as unspoiled and teeming with coral and marine life. Snorkeling here is usually a highlight, thanks to the provided gear and clear waters. Expect to see a variety of colorful fish and vibrant coral formations—an underwater spectacle that keeps both novices and experienced snorkelers entertained.
Koh Madsum & Koh Rap: Quiet Getaways
Koh Madsum stands out as a less crowded, tranquil spot. The reviews mention it as a perfect place for relaxing, with the added bonus of potentially spotting local wildlife and enjoying pristine beaches. Note that there is an admission fee for Koh Madsum, but most travelers find the peace worth it.
Koh Rap is another optional stop, but an admission fee applies here too. Depending on your group’s interests, you may choose to skip or visit briefly—your captain can tailor the route based on your preferences.

Snacking and soft drinks are included, so you can munch on fresh fruit and sip on sodas while taking in the views.

Authentic Touches & Authentic Experiences
Several reviewers highlight the attentive service provided by the crew and captain, especially Alain, the owner, who seems genuinely interested in making sure guests have a memorable day. One guest mentions that Alain even arranged a takeaway dinner for their evening plans, showing the level of personalized care available.
The Value of a Private Charter
While the cost might initially seem high, consider what it includes: fuel, fishing rods, insurance, towels, bottled water, soft drinks, and snorkeling gear. No need to worry about hidden costs or crowded boats; your group’s comfort and freedom are prioritized. Plus, the capacity for up to 10 people ensures the per-person cost is reasonable for a private experience.
The Downside: Cost and Weather Dependency
The main consideration is the price—this tour is an investment in privacy and bespoke service. For smaller groups or couples, it might be pricier than shared tours, but the value is in the exclusivity. Also, weather can impact the day; if poor weather causes cancellation, you’ll be offered a new date or a full refund, which offers peace of mind.
