Koh Mak Travel Guide: Discover Thailand’s Most Underrated Island

Welcome to your ultimate Koh Mak Travel Guide! If you're dreaming of a peaceful island escape without crowds, noisy bars, or tourist traps, you might just fall in love with Koh Mak. Tucked between the more famous Koh Chang and Koh Kood, this little gem in eastern Thailand is still flying under the radar—and that’s exactly what makes it so special.

In this guide, you'll find everything you need to plan your trip: how to get there, when to visit, where to stay, the best things to do in Koh Mak, and tips for getting around. Let’s uncover the charm of Thailand’s most underrated island, one section at a time.

📍 Where is Koh Mak Located?

Koh Mak on the Map: Eastern Thailand’s Tropical Escape

Koh Mak is located in the Gulf of Thailand, nestled between the larger islands of Koh Chang and Koh Kood. It belongs to the Trat Province and is part of the protected Mu Ko Chang National Park archipelago. It also lies very close to the Cambodian border, making it a convenient stop for travelers coming from or heading to Cambodia. Because of its remote location and low development, it has managed to preserve its natural beauty and authentic island vibe.

How Far is it from Bangkok?

While Koh Mak feels like a hidden paradise, it's surprisingly accessible from Bangkok. The total distance is approximately 300 kilometers (about 186 miles), making it ideal for a short getaway. Most travelers choose to take a van or bus from Bangkok to Trat, which typically takes between 4.5 and 5.5 hours depending on traffic. From there, it's just another 1 to 2 hours by ferry or speedboat to reach the island. Because of this manageable journey, Koh Mak is a great choice for those seeking tranquility without going too far off the beaten path.

💡 Travel Tip: For a faster trip, book a domestic flight to Trat Airport, then transfer to Laem Ngop Pier for your boat.

ℹ️ Quick Facts About Koh Mak Island

• 🌊 Area: 16 square kilometers (around 6.2 square miles)
• 👥 Population: Approximately 1,500 residents live on the island
• 🚙 Cars: Almost none! Instead, transportation is primarily done by scooter or bicycle, which keeps the roads peaceful and clean.
• 🏡 Vibe: A quiet, eco-conscious island featuring family-run resorts and homestays.
• 🌱 Power: The island has 24/7 electricity, and mobile reception is generally strong in most areas.
• 🏥 Health: There is one small clinic and a pharmacy available, offering basic healthcare services.

💡 Interesting Fact: Koh Mak is privately owned by a few local families who, over the years, have collaborated to limit development. Because of this, they’ve managed to keep mass tourism away and preserve the island’s natural and cultural integrity.

✈️ How to Get to Koh Mak: Ferries, Buses & Flights

Travel from Bangkok to Koh Mak

You can reach Koh Mak from Bangkok by taking a bus or shared minivan to the coastal town of Trat. This overland journey typically takes around 5 to 6 hours, depending on traffic and weather conditions. Once in Trat, travelers must continue by boat, which can be booked in advance or arranged at the pier.

Alternatively, for those short on time, flying is the fastest and most convenient option. Bangkok Airways operates daily flights from Suvarnabhumi Airport to Trat Airport. The flight takes about 1 hour, followed by a 30- to 40-minute taxi ride to the ferry piers.

Boats to Koh Mak depart from several piers, most commonly Laem Ngop or Ao Thammachat. These piers offer both speedboats and catamarans, and during high season, departures are frequent and well-timed to connect with flight arrivals.  I recommend booking your transportation through 12Go Asia — it's a great platform to compare prices and find the best travel options across Thailand and Southeast Asia – book HERE.

💡 Travel Tip: Try to arrive in Trat before 2 PM to ensure you catch the last boats to the island, especially during low season.

Can You Drive to Koh Mak?

There are no car ferries to Koh Mak, and private vehicles are not allowed. Therefore, even if you drive to the pier, you'll need to leave your car behind.

Ferry Options from Trat to Koh Mak

Ferries and speedboats depart from several piers in Trat, including Laem Ngop, Ao Thammachat, and Center Point Pier. While options may vary by season, most travelers prefer the faster speedboats, which typically take around 45 to 60 minutes to reach Koh Mak. Because of their efficiency and convenience, these boats are ideal for those looking to minimize travel time.

Companies such as Leelawadee and Panan offer direct services to the island, often with multiple departures daily during high season. However, schedules may be reduced during the rainy months, so it’s best to check availability in advance. Book HERE via 12Go Asia to compare prices and find the best travel options.

Getting to Koh Mak from Koh Chang & Koh Kood

Island-hopping is easy! Seasonal speedboats and slow ferries connect Koh Mak with Koh Chang and Koh Kood. Travel times range from 30 minutes to 1 hour depending on weather.
From Koh Mak to Koh Kood, prices tend to be lower—around ฿350–฿550 per person and just 30–60 minutes on the water. 
From Koh Chang to Koh Mak, tickets generally cost ฿500–฿900 per person, depending on boat type. For example, Bang Bao Boat Wooden‑Boat charges about ฿500 and speedboats around ฿600–฿900 per trip. Book HERE via 12Go Asia to compare prices and find the best travel options.

Travel from Cambodia

If you're coming from Cambodia (e.g., Koh Kong), the most common route is to travel by minivan to the town of Trat, which is the main gateway to the islands. This journey typically takes between 4 and 6 hours depending on traffic and border control procedures. Once in Trat, you’ll need to transfer to one of the nearby ferry piers to continue to Koh Mak.

Although border crossings may require some coordination and waiting time, they are generally straightforward and can be completed within a single day. Therefore, this route is a practical option for travelers combining Cambodia and Thailand in one itinerary. Book HERE via 12Go Asia to compare prices and find the best travel options.

💡 Travel Tip: Book combo tickets (bus + boat) online to save time and money.

🐠 What is Koh Mak Famous For?

Though small in size, Koh Mak offers a unique blend of natural beauty, sustainability, and authentic island living. Because it’s still relatively unknown to mass tourism, many travelers are surprised by how tranquil and welcoming the island feels.

Serene Beaches & Hidden Coves

Koh Mak is blessed with long, powdery beaches and a peaceful atmosphere. Unlike party islands like Koh Phi Phi or Koh Samui, you won’t find loud music or beach raves here. Instead, imagine peaceful sunsets, hammocks under palm trees, and the soft sound of waves gently hitting the shore. The beaches here, such as Ao Kao and Ao Suan Yai, stretch for kilometers and are perfect for relaxing walks, swimming, or simply doing nothing at all.

💡 Travel Tip: Head to the far ends of the beaches to discover quieter spots and hidden coves where you might have the entire stretch of sand to yourself.

Eco-Friendly Island Life & Biking

Koh Mak stands out for its dedication to eco-tourism and sustainability. Because the island has no large-scale resorts or nightlife, the environment remains unspoiled. Instead, you'll find coconut plantations, small homestays, and signs encouraging waste reduction and conservation.

Cycling is not just a fun activity but a preferred way to explore. The island’s mostly flat roads make it ideal for all ages. You can easily bike from beach to beach, stopping to enjoy the views or grab a coconut from a local café.

💡 Travel Tip: Rent a bicycle for a day and take the small coastal road loop—it’s scenic, quiet, and lets you see the best of Koh Mak at your own pace.

Snorkeling, Diving & Marine Life

Because of its clear waters and healthy marine ecosystems, Koh Mak is a favorite for snorkeling and diving. Several local operators offer day trips to nearby islands and coral reefs, where you can see clownfish, parrotfish, and even sea turtles. You can also snorkel directly off the beaches. For more adventurous travelers, scuba diving tours can take you to deeper reefs around Koh Rang National Marine Park.

💡 Travel Tip: Bring your own snorkel gear if possible. Rentals are available, but having your own ensures you can explore anytime—even spontaneously from the beach.

Laid-Back Vibe & Island Charm

Koh Mak is perfect for those who want to escape the chaos of bigger Thai islands. There’s no nightlife, no shopping malls, and no fast-food chains—just calm beaches, authentic Thai food, and local smiles. Because of this, the island attracts a more mindful type of traveler—couples, digital nomads, families, and solo adventurers seeking peace.

💡 Travel Tip: Don't expect a party scene. Bring books, download playlists, or start a travel journal—the vibe here is all about slowing down.

☀️ When to Visit Koh Mak: Weather, Seasons & Events

Koh Mak enjoys a tropical monsoon climate, which means it's warm year-round but experiences distinct wet and dry seasons. Therefore, knowing when to visit can significantly enhance your experience, depending on what you're looking for—whether that’s sunshine-filled days, fewer crowds, or lower prices.

Month-by-Month Koh Mak Weather

The climate is typically split into three main periods:

• ☀️ November to February: Dry, cool, and pleasant—ideal for beach activities.
• 🔥 March to May: Hot and humid, with temperatures often reaching their peak.
• 🌧️ June to October: Rainy season with occasional heavy showers, but still plenty of sunshine in between.

Because of the clear weather and calm seas, most travelers prefer to visit during the dry season.

💡 Travel Tip: Even in the rainy season, mornings are often dry—so plan your outdoor activities earlier in the day.

Dry Season: Best Time for Beach Lovers

From November through February, the island sees its best weather. Days are sunny, skies are blue, and humidity is relatively low. It’s the perfect time for beachgoers, snorkelers, and anyone looking to enjoy island life at its finest. However, this is also the high season, so accommodations can fill up quickly.

💡 Travel Tip: Book your stay early if you're planning a visit between December and February, especially during Christmas and New Year.

Rainy Season: Should You Still Visit?

The rainy season stretches from June to October. While heavy rains do occur, they’re usually short-lived and followed by clear skies. Therefore, if you don’t mind occasional showers, you’ll find Koh Mak beautifully green and far less crowded during this period.

💡 Travel Tip: Bring a lightweight rain jacket and quick-dry clothing to stay comfortable between sunbursts and tropical downpours.

Best Time for Budget Travelers & Fewer Tourists

If you're looking to save money and avoid crowds, consider visiting during the shoulder seasons—May to early June or late October to early November. Prices for accommodation drop, and the island remains pleasantly quiet.

💡 Travel Tip: Many resorts offer off-season promotions, so always ask about discounts if you’re booking directly.'

📅 How Many Days to Spend on Koh Mak?

Koh Mak may be small, but it offers enough charm and variety to keep you entertained for days. How long you should stay depends on your travel style—whether you're looking for a quick beach break or a more immersive escape with exploration and relaxation. Here’s how to make the most of your time on the island.

3-Day Koh Mak Itinerary: Beaches & Biking

A 3-day stay on Koh Mak is ideal if you're short on time but still want to recharge in nature. Start your trip with a peaceful day on Ao Kao Beach, then spend your second day cycling around the island to discover coconut plantations, small cafés, and hidden coves. On the final day, enjoy a relaxing Thai massage and a sunset drink at one of the beachfront bars.

Although three days may seem short, the lack of traffic and distractions allows you to slow down and truly enjoy the moment.

💡 Travel Tip: If you're only staying a few days, book accommodation near Ao Kao or Ao Suan Yai to stay close to restaurants and the main beaches.

💸 Is Koh Mak Budget-Friendly?

Koh Mak is not only peaceful and picturesque—it’s also refreshingly affordable. Because it’s less commercialized than nearby islands like Koh Chang or Koh Kood, prices for accommodation, food, and transport are generally lower. Whether you’re traveling on a tight budget or looking for a mid-range retreat, Koh Mak offers excellent value.

How Much Should I Budget Per Day?

On average, budget travelers can comfortably spend ฿800–฿1,200 per day (about €20–€30), which covers a basic bungalow, local meals, and a scooter rental. For mid-range travelers, a daily budget of ฿1,500–฿2,500 (€40–€65) allows for boutique hotels, nicer dining options, and paid activities like boat tours or massages.

💡 Travel Tip: Many accommodations include breakfast, so take advantage of this to reduce your daily food expenses.

Cheaper than Koh Chang or Koh Kood?

Yes—Koh Mak is often cheaper. Because the island is family-owned and has fewer big-name resorts, prices remain fair and local-driven. Compared to Koh Kood, where luxury resorts dominate, or Koh Chang, which caters to package tourism, Koh Mak strikes a great balance between quality and cost.

💡 Travel Tip: Traveling in the shoulder season (May or October) can save you 20–30% on rooms and tours.

3-Day Cost Breakdown (Budget vs Mid-Range)

🛵 How to Get Around Koh Mak

Koh Mak is easy to explore thanks to its compact size and flat roads. You won’t need a car—just choose between a scooter, songthaew, or bicycle.

Scooter Rental – Most Popular & Flexible

Scooters are the top choice for flexibility. Rentals cost around ฿250–฿300/day (€6–€8), and most roads are quiet and easy to ride. However, be cautious on wet or unpaved paths.

Songthaews are affordable shared taxis that run between key spots. Fares are ฿50–฿100 (€1.30–€2.50) depending on distance. While they don’t run on a fixed schedule, they’re a good backup if you’re not renting.

💡 Travel Tip: Ask your hotel to arrange one or wave one down along the road.

Bicycles – Great for Flat Terrain

Because the island is mostly flat, cycling is a pleasant and eco-friendly option. Bike rentals start at ฿100–฿150/day (€2.50–€4) and are perfect for exploring slowly.

💡 Travel Tip: Avoid riding during the hottest hours—early morning or late afternoon is best.

🍜 Where to Eat on Koh Mak: Local Food, Markets & Beach Cafés

You won’t find big chains or nightclubs here—but that’s exactly the charm. Koh Mak’s food scene is casual, local, and packed with flavor. Whether you want a beachfront Thai curry or a sunset cocktail, here’s where (and what) to eat on the island.

Must-Try Thai Dishes

• • Pad Thai (fried noodles)
  • Som Tam (green papaya salad)
  • Massaman Curry (mild and creamy)
  • Tom Yum Soup (spicy and tangy)
  • Mango Sticky Rice (dessert perfection) 💡 Travel Tip: Ask for “not too spicy” unless you’re used to Thai heat!

Best Beach Restaurants & Sunset Bars

• • Koh Mak Seafood: Fresh catch, casual setting, great value.
  • Ball Cafe: Beachfront dining on Ao Suan Yai with relaxed vibes.
  • Blue Pearl Bar: Perfect for drinks at sunset.
  • Food Art Hut: Local dishes served with a creative twist. 💡 Travel Tip: Sunset hour is busy—reserve ahead if you want a front-row seat to the view.

Local Night Markets & Street Food

There’s no permanent night market, but pop-up stalls appear near the piers or main roads during high season. Street food is limited but you’ll still find Thai pancakes, skewers, and iced drinks at budget-friendly prices.

💡 Travel Tip: Check with your hotel about upcoming market nights—they’re not advertised widely.

🪰 Watch Out for Sandflies on the Beach!

One important thing to prepare for when visiting Koh Mak is the presence of sandflies. These tiny insects are often found on quiet, shaded beaches—especially during early mornings and late afternoons. Although they may be hard to see, their bites can be incredibly itchy and last for several days.

While insect repellent can help to some extent, many travelers say the only truly effective solution is applying coconut oil directly to the skin. It creates a natural barrier that discourages sandflies from landing.

💡 Travel Tip: Coconut oil is much cheaper on the mainland or in larger cities. Buy a bottle before arriving on the island, as prices on Koh Mak are noticeably higher.

🌅 Final Thoughts: Is Koh Mak Worth Visiting?

Absolutely. Koh Mak is one of those rare islands that still feels authentic, unspoiled, and deeply peaceful. Its lack of mass tourism and commercial development is what makes it so special—and why many travelers fall in love with it.

What sets Koh Mak apart is its eco-conscious charm, warm community, and slow pace of life. You won't find flashy attractions, but you will find postcard-perfect beaches, family-run resorts, and genuine connections with locals.

It’s a dream destination for couples, slow travelers, digital nomads, and nature lovers. If you're seeking nightlife, shopping malls, or crowds—this might not be your island. But if you value calm, connection, and natural beauty, it absolutely is.

Despite growing interest in the island, Koh Mak is still underrated—especially compared to its neighbors. However, that’s changing quickly. As word spreads, more travelers are beginning to discover its charm.
