Thailand has long been one of the world’s most beloved tropical destinations - and for good reason. With its warm climate, welcoming locals, and postcard-perfect islands, it’s the kind of place where every day feels like a dream. With INTRO Travel’s new Thai Island Explorer tour , there’s never been a better time to explore Thailand’s southern coastlines and discover the islands that continue to steal the spotlight year after year.

Koh Samui – Relaxed Luxury and Island Charm

As one of Thailand’s most accessible islands, Koh Samui offers a well-rounded mix of nature, culture, and comfort. Whether you're wandering through coconut groves, visiting sacred temples, or simply enjoying the beautiful beaches, Koh Samui balances adventure and relaxation effortlessly.

Don’t miss:

• Exploring Wat Plai Laem and Big Buddha Temple
• A stroll through Fisherman’s Village at sunset
• Swimming at hidden beaches tucked into the island’s lush coastlines
  
  

Koh Phangan – More Than Just a Party Island

Though famous for its Full Moon Party, Koh Phangan has much more to offer beyond the dance floor. Its quieter western beaches are ideal for catching sunsets, while its lush interior is home to waterfalls, viewpoints, and jungle trails.

Top experiences:

• Watching the sunset from Haad Yuan or Secret Beach
• Exploring the island on a guided tour
• Trying a beginner-friendly Muay Thai class
  
  

Koh Tao – A Snorkeller’s Paradise

For ocean lovers, Koh Tao is one of Thailand’s most rewarding island destinations. Known for its clear waters and coral reefs, it’s ideal for snorkelling, diving, and soaking up the sea.

Highlights include:

• Snorkelling at Ao Leuk, Shark Bay, or Hin Wong Bay
• A boat trip to nearby Koh Nang Yuan, one of Thailand’s most photographed spots
• Scuba diving – with options for both beginners and experienced divers
  
  

Krabi (Railay & Ao Nang) – Limestone Cliffs and Lagoon Views

Technically part of the mainland, Krabi offers some of Thailand’s most dramatic scenery. Limestone cliffs rise straight from turquoise waters, creating the perfect setting for kayaking, rock climbing, and boat trips.

What to explore:

• A day trip to Railay Beach, accessible only by boat
• Kayaking through mangrove forests and tranquil lagoons
• Watching the sunset from Ao Nang’s beachfront promenade
  
  

Koh Phi Phi – Iconic Beauty and Island Energy

Few places capture the imagination quite like Koh Phi Phi. With its towering cliffs, emerald bays, and vibrant nightlife, this island group offers the best of both worlds — natural beauty by day and a lively scene by night.

Don’t miss:

• Hiking to the Phi Phi Viewpoint for a panoramic sunrise or sunset
• Snorkelling and swimming around Phi Phi Leh and Maya Bay
• Exploring hidden coves by kayak or longtail boat
  

Thailand’s southern islands are more than just stunning beaches — they’re full of culture, adventure, and unforgettable moments. From snorkelling in Koh Tao’s crystal-clear waters to kayaking beneath Krabi’s limestone cliffs and watching the sun set over Phi Phi, each island offers something unique.
