Bali, Indonesia, is one of those rare places that gives something for every kind of traveler. It’s world-famous for its surfing beaches like Kuta and Seminyak, where both beginners and pros ride the waves.

Koh Samui is one of Thailand’s most loved islands because it blends luxury and relaxation so effortlessly. It’s the kind of place where you can spend your morning at a five-star beach resort and your afternoon exploring hidden waterfalls or relaxing on a quiet stretch of sand. The island is known for its laid-back atmosphere, yet it still gives everything from wellness retreats to buzzing beach bars.
A must-see on the island is the Big Buddha Temple, home to a towering 12-meter golden statue that watches over the coast and gives a peaceful spot for reflection and sea views.

Havelock Island, officially known as Swaraj Dweep, is one of the most beautiful and peaceful islands in India, located in the Andaman and Nicobar Islands. It’s famous for having some of the cleanest and most pristine beaches in the country, with soft white sand and clear turquoise waters.

What makes Havelock truly special is how quiet and laid-back it feels. There are no big crowds or city noise, just nature, calm beaches, and friendly locals. It’s the perfect place to disconnect from daily life and reconnect with the ocean.
5. Jeju Island, South Korea
Jeju Island is South Korea’s most popular island getaway, and it feels completely different from the busy cities like Seoul or Busan. Its charm comes from its dramatic volcanic origins, with craters, lava tubes, and black rock coastlines that still reflect the island’s fiery past.
One of the main highlights is Hallasan, South Korea’s highest mountain, which sits right in the middle of the island. Hiking up Hallasan gives you stunning views, especially in spring when the wildflowers bloom or in winter when it’s dusted with snow.
Another must-see is the network of lava tubes, like the Manjanggul Cave, which are natural underground tunnels created by flowing lava. Walking through them feels like stepping into another world. The island is also famous for its beautiful waterfalls, such as Jeongbang and Cheonjiyeon, which are perfect for scenic photos and relaxing nature walks.
Jeju has its own unique island culture too, from the local Haenyeo women divers who free-dive for seafood to the sweet Jeju tangerines that grow all over the island.
6. Langkawi, Malaysia
Langkawi, often called the Jewel of Kedah, is a stunning island destination off the northwest coast of Malaysia. It’s known for its duty-free shopping, which means you can buy chocolates, alcohol, perfumes, and more at lower prices, making it a favorite for both locals and tourists.
Langkawi is much more than just shopping. The island is filled with natural beauty, from calm beaches and turquoise waters to lush rainforests and hidden waterfalls.
One of the island’s biggest attractions is the Langkawi Sky Bridge, a curved bridge suspended high above the mountains that gives you jaw-dropping views of the island and the sea beyond.
You can reach it by taking the Langkawi Cable Car, one of the steepest in the world, which takes you up to the top of Gunung Mat Cincang. Nature lovers will enjoy mangrove tours in the Kilim Geoforest Park, where you can explore caves, spot eagles, and even visit a floating fish farm.
Langkawi is also the best base for island-hopping, as it’s surrounded by smaller, quieter islands that offer snorkeling, kayaking, and beach picnics. With its mix of shopping, adventure, and relaxation, Langkawi is perfect for families, couples, or solo travelers looking for a peaceful yet exciting island experience in Malaysia.
One of the most comprehensive official sites for island travel in Asia is the Tourism Authority of Thailand’s “Amazing Thailand” website, which covers popular destinations like Phuket, Koh Samui, and Maya Bay: https://campaign-landing.tourismthailand.org/
7. Phu Quoc, Vietnam
Phu Quoc is also known for its fragrant pepper farms, where visitors can walk through lush plantations, learn about the growing process, and sample freshly harvested black pepper straight from the source.
Despite recent tourism growth, much of the island remains relatively undeveloped, making it an appealing destination for nature lovers and those seeking a quieter travel experience. Phu Quoc is known for its clear turquoise waters, tropical forests, and relaxed coastal environment.
One of the most unique spots here is Starfish Beach, where the shallow, calm waters are filled with bright red starfish just beneath the surface—an unforgettable sight, especially at sunset.
The island’s night markets are buzzing with life and filled with delicious Vietnamese street food, souvenirs, and fresh seafood grilled right in front of you. Phu Quoc is also known for its fragrant pepper farms, where visitors can walk through lush plantations, learn about the growing process, and sample freshly harvested black pepper straight from the source.
In fact, Phu Quoc is also well known for producing nuoc mam, a traditional Vietnamese fish sauce that’s exported around the world.
8. Siargao, Philippines
Siargao has earned its reputation as the Philippines’ ultimate surf spot, drawing wave lovers from around the world. It’s home to Cloud 9, one of the most famous surf breaks in Asia, attracting surfers from around the world.
What makes Siargao truly special is that it’s not just for surfers. Now it’s also become a rising hub for ecotourism, with travelers coming to enjoy its unspoiled nature, slow-paced lifestyle, and focus on sustainability.
Beyond the waves, Siargao gives stunning island-hopping adventures to nearby islets like Daku Island, Guyam Island, and Naked Island, where you’ll find powdery white sand, turquoise waters, and palm-lined shores.
Siargao is also home to serene spots like Sugba Lagoon, where visitors can paddleboard, take a swim, or simply relax and enjoy the calm, emerald-green waters surrounded by lush cliffs. Magpupungko Rock Pools appear during low tide, revealing clear, calm waters and natural rock formations perfect for a refreshing dip and stunning photos.
Despite its growing popularity, Siargao still feels untouched, with simple beach huts, motorbike rides through coconut groves, and a close-knit island community. It’s the kind of place where you can surf in the morning, explore nature in the afternoon, and enjoy a laid-back beach dinner under the stars.
9. Gili Islands, Indonesia
Just off the coast of Lombok, the Gili Islands are a trio of idyllic escapes that look like they’ve been pulled straight from a travel magazine. What sets them apart is their peaceful, car-free lifestyle. There are no cars or motorbikes here, only bicycles, horse-drawn carts (called cidomo), and sandy paths perfect for barefoot strolls. This slow, quiet pace is part of the islands’ charm.
Each island has its personality. Gili Trawangan is the liveliest, known for its beach bars and sunset parties. Gili Meno is the most peaceful of the three, perfect for honeymooners or those seeking total tranquility, while Gili Air blends mellow island life with a touch of social energy just right for relaxed explorers.
Surrounded by clear turquoise waters and colorful coral reefs, the Gilis are a paradise for divers and snorkelers. A favorite activity is snorkeling with sea turtles, often spotted just a few meters from shore. And no visit is complete without a photo on the famous beach swings, especially at sunset, when the sky turns into a canvas of golden and rosy hues.
10. Okinawa, Japan
Okinawa, the southernmost prefecture of Japan, consists of over 150 islands, each offering something special. With powdery white beaches and clear turquoise seas, Okinawa is a diver’s paradise, especially near the Kerama Islands, where thriving coral reefs teem with tropical fish and sea turtles.
But Okinawa isn’t just about beaches. It has a unique cultural identity shaped by its Ryukyu Kingdom past, which you can see in its music, clothing, and especially its food. Okinawan cuisine includes favorites like goya champuru and Okinawa soba.
One of the island’s most iconic landmarks is Shurijo Castle, a UNESCO World Heritage Site that was once the royal palace of the Ryukyu kings. Although it was damaged by fire in 2019, restoration efforts are ongoing, and the site still holds deep cultural significance.
11. Koh Yao Noi, Thailand
Despite its location just 30 minutes by boat from Phuket, Koh Yao Noi has remained largely untouched by mass tourism, preserving its traditional Muslim fishing communities and sustainable, nature-based lifestyle.
The island is dotted with laid-back fishing villages, where locals live simply and traditionally, offering a glimpse into rural Thai island life. You won’t find big hotels or loud nightlife here. Instead, eco-friendly resorts and bungalows blend into the natural surroundings, many built with sustainability in mind.
The island is also home to lush mangrove forests, rice paddies, and quiet beaches with views of the dramatic limestone karsts that rise from the sea, just like in nearby Phang Nga Bay. You can spend your days biking through coconut groves, kayaking through mangroves, or enjoying a Thai cooking class with local families.
For travelers who want to slow down, reconnect with nature, and experience Thailand without the crowds, Koh Yao Noi gives the perfect hidden island escape.
12. Koh Rong Samloem, Cambodia
Koh Rong Samloem is one of Cambodia’s most peaceful island escapes, often overshadowed by its more famous neighbor, Koh Rong, but that’s exactly what makes it special.
While Koh Rong has become known for beach parties and nightlife, Koh Rong Samloem remains quiet and laid-back, ideal for travelers looking to unplug and soak in nature. The island sits off Cambodia’s southern coast in the Gulf of Thailand and is accessible by a short boat ride from Sihanoukville.
One of the island’s most magical experiences is witnessing bioluminescent plankton at night, tiny glowing organisms that light up the water when you move through it, creating a surreal, starry effect in the sea. By day, you can explore the island’s white-sand beaches, swing in a seaside hammock hostel, or hike through tropical jungle trails that connect remote coves and quiet bays.
There’s very little development here: no cars, minimal electricity in some areas, and accommodations ranging from eco-resorts to simple beach bungalows. If you’re craving slow mornings, ocean swims, jungle walks, and nights under the stars, Koh Rong Samloem gives a raw and refreshing island experience that still feels like a secret.
13. Raja Ampat, West Papua, Indonesia
Raja Ampat, located off the northwest tip of West Papua, Indonesia, is one of the most stunning and biodiverse island regions in the world. This remote paradise is made up of over 1,500 small islands, with dramatic limestone cliffs, hidden lagoons, and turquoise waters that seem untouched by time.
What truly sets Raja Ampat apart is what’s beneath the surface. It’s often called the “Amazon of the Seas” because it’s home to more than 75% of the world’s coral species and over 1,300 species of tropical fish.
That makes it a dream destination for divers and snorkelers, who come from all over the world to explore its vibrant reefs, sea turtles, manta rays, and even rare creatures like the walking shark.
Above water, the scenery is just as magical. The islands are covered in lush jungle and give peaceful boat rides through emerald bays and secret coves. Unlike many touristy islands, Raja Ampat is still largely undeveloped, with small eco-lodges and homestays that work closely with local communities to preserve the environment.
Getting there takes effort; it usually involves flying to Sorong and taking a ferry, but those who make the journey are rewarded with raw natural beauty and a sense of true escape.
14. Maya Bay, Thailand
Maya Bay, located on Koh Phi Phi Leh in southern Thailand, is one of the most iconic and visually stunning beaches in the world. It rose to worldwide fame after appearing in the 2000 film The Beach starring Leonardo DiCaprio, turning it into a must-visit spot for travelers chasing tropical beauty.
For years, the bay attracted massive crowds, but to protect its fragile ecosystem, it was closed to tourists in 2018 for a major restoration project. Coral reefs were replanted, and the marine environment was allowed to heal.
Maya Bay reopened in 2022 with strict conservation rules: swimming is now prohibited, and boats must enter from a designated rear dock, all to protect its fragile ecosystem and keep the bay pristine for future visitors.
Despite the regulations, visiting Maya Bay is still an unforgettable experience. You can walk along the soft white sand, take in the dramatic cliff views, and soak up the peaceful, protected atmosphere that once again makes the bay feel wild and untouched.
