Day Trip to Ang Thong National Marine Park

Ang Thong Marine Park is a stunning archipelago of 42 islands in the Gulf of Thailand, and it’s easily the #1 Koh Samui day tour for first-time visitors.

This national park is a paradise of towering limestone cliffs, hidden lagoons, lush jungles, and white‑sand beaches, offering a mix of adventure and relaxation in one day. Exploring here feels like stepping into a postcard.

Most travelers visit on a day tour from Koh Samui, and the most popular option is the semi‑private sunset cruise.

This tour takes you through highlights like Emerald Lake and the Blue Lagoon, with stops for snorkeling in coral‑rich waters and kayaking through hidden coves.

Your trip typically includes round‑trip hotel transfers, snorkeling gear, towels, drinks, and lunch, making it a seamless experience.

So, is Ang Thong Marine Park worth it? Absolutely. Hiking to the viewpoints for panoramic island views, snorkeling among vibrant marine life, and cruising past the dramatic karst formations make this a must‑do Koh Samui excursion!

4WD Jungle Safari Adventure in Koh Samui

Koh Samui’s lush interior is a playground for adventure lovers, and the 4WD Jungle Safari Tour is one of the best ways to experience it.

On this day trip, you’ll ride in a rugged, open‑air ex‑army jeep through tropical forests and up winding mountain roads, passing small villages, coconut groves, and scenic viewpoints along the way.

It’s the perfect chance to see a wilder, more authentic side of the island that most visitors miss. Highlights during the tour include the following:

• Visiting Grandmother and Grandfather Rocks (Hin Ta and Hin Yai), the island’s iconic rock formations.

• Swimming in the natural pool at Koh Samui’s tallest waterfall.

• Flying through the trees on two short zip lines, perfect for a little adrenaline rush.

• Stopping at panoramic viewpoints, Big Buddha, and the serene Magic Buddha Garden tucked in the hills.

This tour combines sightseeing with adventure, letting you see some of the top attractions in Koh Samui in a single day.

A Thai lunch and hotel pickup/drop‑off are included, making it hassle‑free from start to finish.

Koh Tao Snorkeling Tour from Koh Samui

Koh Tao is a small, laid‑back island off the coast of Surat Thani, and it’s a paradise for anyone who loves the water.

The island is world‑famous for its vibrant coral reefs and abundant marine life, making it one of the top destinations in Thailand for snorkeling and diving.

It’s also one of the most affordable places in the world to get a scuba diving license, which is why you’ll notice dive schools scattered all over the island. Even if you’re not looking to get certified, a day trip here is perfect for snorkeling and enjoying the island’s natural beauty.

On this Koh Tao snorkeling tour from Koh Samui, you’ll board a speedboat and visit two prime snorkeling spots around the island.

Expect to see colorful fish, healthy coral reefs, and crystal‑clear waters perfect for swimming. A Thai buffet lunch and hotel pickup/drop‑off are included, so the entire day is easy and stress‑free.

Beyond the water, Koh Tao’s charm lies in its relaxed and remote feel. Palm‑fringed beaches, lush hills, and a tranquil atmosphere make it a refreshing escape from the busier Koh Samui.

Pig Island Day Trip (Ko Mat Sum)

Just a short boat ride south of Koh Samui lies Ko Mat Sum, better known as Pig Island, where friendly pigs roam freely on the sand and sometimes even wade into the water.

If you’ve ever wondered why pigs live here, the story is pretty simple: a local once saved a single pig, and over time, the population grew. Today, the island has become one of the most unique and fun Koh Samui day tours for travelers looking for something different.

This Pig Island tour usually includes a visit to the nearby island of Ko Tean, giving you two experiences in one trip.

Spend your day snorkeling in the clear waters, kayaking along the coast, and relaxing on quiet beaches with postcard‑worthy views.

Most tours include a Thai lunch and wrap up with a scenic ride back to Koh Samui just in time for sunset. Between the playful pigs and the laid‑back island vibes, this is a day trip that’s as memorable as it is fun.

ATV Quad Adventure in Koh Samui

Koh Samui’s dense tropical jungle makes it the perfect playground for adventure, and riding an ATV through the island’s rugged trails is an unforgettable way to explore it.

This ATV Quad Tour lets you choose between a morning or afternoon ride, taking you along off‑road jungle paths with plenty of twists, turns, and scenic viewpoints along the way.

After your adrenaline‑filled ride, the tour includes a stop at one of Koh Samui’s hidden waterfalls, giving you a chance to cool off and snap some photos before heading back.

Snacks, drinks, and round‑trip hotel pickup are included, making this a hassle‑free adventure for travelers looking to see a wilder side of the island.

Ethical Elephant Sanctuary Visit in Koh Samui

Visiting an elephant sanctuary in Thailand is a must‑do experience. Seeing these gentle giants up close, feeding them, walking beside them, and watching them interact freely is something you’ll remember forever.

However, not all sanctuaries are created equal. Some facilities exploit elephants with rides, constant flash photography, and restrictive chaining.

Ethical sanctuaries never offer elephant rides or performances and instead focus on rescue, rehabilitation, and proper care.

Samui Elephant Sanctuary is the island’s first entirely ethical elephant sanctuary and one of the best places to experience elephants responsibly. Guests can feed, observe, and walk alongside the elephants while learning about their stories and conservation.

For the most rewarding experience, book in advance, as group sizes are limited to ensure the elephants’ comfort.

Koh Samui Sightseeing & Island Highlights Tour

If you want to experience all of Koh Samui’s top attractions in a single day, the Koh Samui Sightseeing Tour is the perfect choice.

This action‑packed tour takes you to the island’s must‑see landmarks, including the Big Buddha Temple, Wat Plai Laem, Lad Koh View Point, and Na Muang Waterfall.

This list only covers a few of the places you’ll see on the tour, but by the end of the day, you’ll have explored the very best of Koh Samui, from cultural temples to lush natural spots.

It’s an excellent option if you’re short on time and want to see the highlights without planning your route.

With hotel pickup and drop‑off included, it’s a stress‑free way to make the most of your day on the island.

Thai Cooking Class and Organic Farm Tour in Koh Samui

One of the most memorable Koh Samui day tours is spending the day learning to cook authentic Thai dishes with Chef Lat in a hands‑on, farm‑to‑table experience that blends food, culture, and nature.

During the class, you’ll prepare some of Thailand’s most famous foods: Pad Thai, spicy Thai basil with chicken or tofu, Tom Yum with prawns, and papaya salad (som tum).

What makes this Thai cooking class special is that you’ll pick fresh herbs directly from the farm before cooking, creating an experience that’s as authentic as it is delicious.

Cooking classes are one of my favorite ways to connect with a destination, you not only learn the recipes but also gain a cultural experience as you cook alongside a local chef.

By the end of the session, you’ll head home with a few authentic Thai recipes under your belt and a deeper appreciation for the flavors of Thailand.

Full Moon Party Night Transfer from Koh Samui

If there’s one thing Koh Phangan is world‑famous for, it’s the legendary Full Moon Party that takes over Haad Rin Beach once a month. Travelers from around the globe flock to this small island for an all‑night beach celebration unlike anywhere else in Thailand.

The story dates back to the mid‑1980s, when a group of backpackers threw a beach party under the full moon with a few locals.

That casual gathering evolved into the iconic monthly event that now attracts thousands of visitors.

What to expect at a Full Moon Party?

• A long stretch of beach lined with multiple parties and DJ stages
• Diverse music genres, from EDM and techno to reggae and pop
• Neon lights, fire dancers, and plenty of glow‑painted partygoers
• Tourists from all over the world dressed in colorful, creative outfits

Today, Full Moon Parties are a must‑do experience for anyone seeking Thailand’s ultimate nightlife adventure.

From Koh Samui, the easiest way to experience it is by booking a round‑trip Full Moon Party tour, which includes ferry transfers to Koh Phangan and back the next morning, so you can party without worrying about logistics.

Do Full Moon Parties happen on Koh Samui?

Not officially. While some beach clubs host small “Full Moon‑inspired” events, they’re nowhere near the size or energy of the real thing. If you’re curious about Koh Samui nightlife, it’s typically more about casual beach bars, sunset lounges, and relaxed evening spots.

Not officially. Some beach clubs host small “Full Moon‑style” events, but they’re nothing like the real party. There’s still plenty of Koh Samui nightlife to experience, from lively beach bars to sunset lounges and casual evening spots.

Best Islands to Visit Near Koh Samui

Koh Samui is surrounded by several incredible islands, each offering its own unique experience.

While many visitors explore them via organized day tours, you can also visit some of these islands independently if you prefer a more flexible adventure.

If you’re short on time, day tours are the easiest way to explore multiple islands without worrying about ferry schedules. But if you prefer freedom, Koh Tao and Koh Pha Ngan are easy to reach on your own for a whole or overnight trip.

• Koh Pha Ngan – This island is known for its relaxed atmosphere, remote beaches, and beautiful jungle hikes. Travelers can spend the day exploring hidden coves, swimming in turquoise waters, or trekking through lush forest trails to scenic viewpoints and waterfalls. It’s perfect for those who want a slower pace and a taste of untouched island life.

• Koh Tao – Known for world‑class diving and snorkeling, Koh Tao can also be visited independently by ferry. Many travelers combine it with a snorkeling tour for access to the best coral reefs and hidden bays.

Other nearby islands are best experienced with organized tours, as they require special boats or permits:

• Ang Thong Marine National Park – A collection of 42 small islands featuring emerald lagoons, hidden beaches, and lush limestone cliffs. Tours often include kayaking, snorkeling, and short hikes to viewpoints.

• Ko Mat Sum (Pig Island) – Home to the famous swimming pigs and a favorite stop for snorkeling and photos.

• Ko Tean – A quiet island with calm beaches and excellent snorkeling, often paired with Pig Island on boat tours.

What to Pack for a Koh Samui Day Tour

Before heading out on any of these Koh Samui day trips, it’s worth planning ahead to make the most of your adventure.

From packing essentials to arranging transportation, a little preparation goes a long way.

If you haven’t decided on your travel dates yet, consider the best time to visit Koh Samui for sunny skies and calm seas, which makes these day tours even more enjoyable.

• Coral Friendly Sunscreen – Make sure you bring a biodegradable, coral reef-friendly sunscreen. 

• Dry Bag – Consider bringing a dry bag throughout your boat adventures. A dry bag will ensure your things stay dry!

• Fast Drying Towel – A towel is necessary, of course. But the best towel to bring is something made from microfibre, which drys quickly. You’ll be in and out of the ocean frequently, so always having a dry towel is convenient!

• Travel Insurance – You never know what may happen when visiting a foreign country; hospital visits in Thailand can add up—boat accidents, food poisoning, flight cancelations, etc. Don’t take the risk!

Koh Samui Day Trips: Final Thoughts for Travelers

Exploring Koh Samui through day trips is one of the best ways to experience the island’s variety, from jungle waterfalls and cultural landmarks to nearby islands with crystal‑clear waters.

Whether you’re snorkeling in Koh Tao, cruising around Ang Thong Marine Park, or learning to cook authentic Thai dishes, each tour offers a unique memory to bring home.

Not every adventure requires you to take a tour; ferries to Koh Tao and Koh Pha Ngan make it easy to explore at your own pace, but guided trips are ideal if you want convenience and to pack multiple highlights into a single day.

If you’re planning your first visit, mix a few Koh Samui day trips with relaxed beach time and evenings enjoying the island’s vibrant dining and nightlife.

And if you’re deciding where else to go in Thailand afterward, comparing Koh Samui vs Krabi can help you choose your perfect next stop.
