A detailed map of Thailand’s islands reveals two primary coastal regions, each with distinct characteristics and weather patterns: the Andaman Sea on the west coast and the Gulf of Thailand on the east. This geographical division dictates the best time to visit certain islands and helps travelers choose destinations that align with their interests and travel style.
Navigating the Andaman Sea Islands
The Andaman Sea, located off Thailand’s west coast, is famous for its dramatic limestone karsts, crystal-clear turquoise waters, and spectacular diving sites. This region is home to some of Thailand’s most iconic islands, offering a blend of developed tourist hubs and untouched natural beauty. The high season for the Andaman Sea typically runs from November to April, when the weather is dry and sunny.
Phuket: The Grand Dame of Thai Islands
Phuket is Thailand’s largest island and arguably its most famous. Connected to the mainland by a bridge, it serves as a major international gateway. On a map, Phuket stands out as a sprawling destination offering a vast array of resorts, restaurants, and entertainment options. Its diverse landscape includes vibrant Patong Beach, the serene Kata and Karon beaches, and the charming Old Town.
What makes Phuket a must-visit? Its accessibility, luxurious accommodations, and a wide range of activities, from watersports and golf to cultural shows and bustling markets. For those wondering about which island is cheaper, Phuket or Krabi? Generally, Krabi (and its islands) can offer more budget-friendly options, especially regarding guesthouses and local eateries, though both have a spectrum of prices.
The Iconic Phi Phi Islands: A Postcard Paradise
Southeast of Phuket and Krabi lie the Phi Phi Islands, an archipelago that shot to fame with the movie ‘The Beach.’ Koh Phi Phi Don is the main island, offering accommodation and nightlife, while the uninhabited Koh Phi Phi Leh is home to the world-renowned Maya Bay. A map clearly illustrates their close proximity, making island hopping between them a popular activity.
Visiting Maya Bay requires careful planning, as access is regulated to protect its delicate ecosystem. Boat tours from Phuket or Krabi are the most common way to experience these breathtaking limestone cliffs and emerald waters, a testament to Thailand’s natural splendor.
Koh Lanta: Laid-back Charm for Families and Couples
Further south in the Andaman Sea, Koh Lanta offers a more relaxed and family-friendly atmosphere compared to its bustling neighbors. Its long, sandy beaches, lush interior, and welcoming local communities make it ideal for those seeking tranquility. The island is also a popular spot for diving and snorkeling, with numerous dive shops catering to all skill levels.
Koh Lanta is a great choice for travelers looking to escape the crowds and enjoy a slower pace of life. Its map shows a long, narrow island, with most resorts and activities concentrated along its western coast, providing ample opportunities for stunning sunset views.
The Similan and Surin Islands: Diver’s Dream Destinations
For serious divers and snorkelers, the Similan and Surin Islands national parks are unparalleled. These protected archipelagos, located off the coast of Phang Nga province, are consistently ranked among the world’s top dive sites. A map highlights their remote location, accessible primarily by liveaboard boats or day trips from Khao Lak.
The islands boast pristine coral reefs, diverse marine life including whale sharks and manta rays, and incredibly clear waters. Due to their status as national parks, tourism is strictly regulated, and they are typically open only from November to May to allow for ecological recovery.
Koh Lipe: The Maldives of Thailand
At the southernmost tip of the Andaman Sea, near the Malaysian border, lies Koh Lipe. Often dubbed the ‘Maldives of Thailand’ for its impossibly white sands and brilliant turquoise waters, it’s a small island that can be explored on foot. Its map shows three main beaches: Sunrise Beach, Sunset Beach, and Pattaya Beach, each offering a distinct vibe.
Koh Lipe is part of the Tarutao National Marine Park, ensuring its surrounding waters are teeming with marine life, making it excellent for snorkeling and diving directly from the beach. It’s an ideal destination for those seeking pristine natural beauty and a laid-back, barefoot island experience.
Exploring the Gulf of Thailand Islands
On the eastern side of Thailand, the Gulf of Thailand presents a different set of island experiences. The weather patterns here are generally opposite to the Andaman Sea, with the best time to visit typically from May to September, though the dry season extends from December to February for some islands. The Gulf is known for its calmer waters and vibrant coral reefs.
The Samui Archipelago: Koh Samui, Koh Phangan, and Koh Tao
This trio forms the most famous island group in the Gulf of Thailand. A map of this area clearly shows their close proximity, making island hopping between them incredibly convenient and popular among travelers.
Koh Samui: Luxury and Diversity
Koh Samui is the second-largest island in Thailand and a well-established tourist destination. It offers a sophisticated blend of luxury resorts, fine dining, and beautiful beaches like Chaweng and Lamai. Beyond the upscale amenities, visitors can explore waterfalls, Buddhist temples, and vibrant local markets.
Samui caters to a wide range of travelers, from honeymooners to families, offering everything from quiet beach bungalows to opulent villas. It’s easily accessible via its own international airport, making it a popular starting point for exploring the Gulf islands.
Koh Phangan: Beyond the Full Moon Party
Just north of Koh Samui, Koh Phangan is famous globally for its legendary Full Moon Party at Haad Rin Beach. However, a map reveals that the island is much more than just a party destination. Its northern and western coasts offer serene beaches, yoga retreats, and a bohemian atmosphere, perfect for those seeking peace and spiritual rejuvenation.
Many visitors discover a different side of Koh Phangan, with secluded coves, jungle treks, and a thriving wellness scene. It’s an island of contrasts, appealing to a diverse crowd of backpackers and luxury seekers alike.
Koh Tao: The Diving Capital
The smallest of the Samui Archipelago, Koh Tao (meaning ‘Turtle Island’) is a world-renowned hub for scuba diving and snorkeling. Its calm, clear waters and abundant marine life make it an ideal place to learn to dive or to enjoy advanced diving expeditions. The island is dotted with numerous dive schools, offering competitive prices and excellent instruction.
Koh Tao’s compact size means everything is easily accessible, from its beautiful bays like Sairee Beach and Chalok Baan Kao to its scenic viewpoints. For many, it’s the answer to what is the best island in Thailand for diving?
The Koh Chang Archipelago: Nature’s Untouched Beauty
Further east in the Gulf, close to the Cambodian border, lies the Koh Chang Archipelago. Koh Chang is Thailand’s second-largest island, characterized by its mountainous interior, dense jungle, and numerous waterfalls. Its map shows a rugged landscape, less developed than Phuket or Samui, offering a more adventurous and natural experience.
Visitors to Koh Chang can enjoy trekking through the jungle to discover hidden waterfalls, kayaking through mangroves, or simply relaxing on its beautiful beaches such as White Sand Beach and Klong Prao Beach. The island is part of a marine national park, ensuring its natural beauty is preserved.
Koh Kood and Koh Mak: Tranquil Retreats
South of Koh Chang are the smaller, even more tranquil islands of Koh Kood (also spelled Koh Kut) and Koh Mak. These islands are perfect for those seeking ultimate relaxation and an escape from the crowds. A map shows their relatively isolated positions, making them ideal for a peaceful getaway.
Koh Kood boasts pristine white-sand beaches, crystal-clear waters, and luxurious resorts, often described as a hidden gem. Koh Mak offers a simpler, more rustic charm, popular with independent travelers and those looking for an eco-friendly experience. Both are fantastic for snorkeling, kayaking, and simply unwinding.

- Seasonal Considerations: The Andaman Sea is best from November to April, while the Gulf of Thailand generally shines from May to September (though December-February is also good for the Gulf).

While definitions vary, commonly referred to main islands include Phuket (Andaman), and Koh Samui, Koh Phangan, Koh Tao (Gulf), or sometimes Phuket, Phi Phi, and Koh Lanta for the Andaman side.
