So here it goes, pack your bags, grab sunscreen, and get ready to explore the best of Thailand's Andaman coast.

Why Andaman Coast?

The Andaman coast is island-hopping paradise. To the west of Thailand, it comprises a handful of the most beautiful islands in the entirety of Southeast Asia. The sea is famous for its crystal-clear waters, vibrant coral reefs, and diverse marine life, making it very suitable for snorkeling and diving. The islands come in all sizes and characters, offering something for everyone—from busy party scenes to quiet retreats.

Must-visit Islands on the Andaman Coast

Phi Phi Islands

Overview: Though the most famous of all, the Phi Phi Islands need no introduction, after having starred in the movie The Beach. Dramatic limestone cliffs, waters that sparkle like crystals, and an eponymous nightlife characterize the islands.

Highlights: Activities include trips to Maya Bay, the famous beach from the movie The Beach; snorkeling in the crystal-clear waters of Loh Samah Bay; or hiking up to the Phi Phi Viewpoint to get a panorama of the islands. Afterward, in the evening, discover dynamic beach bars and fire shows.

Tips: Especially during peak season, Phi Phi Islands are very touristic. Spending a night on Phi Phi Don—the main island—lets one experience a much more tranquil side of these islands in the early morning or late afternoon.

Similan Islands

Overview: The Similan Islands are a group of nine islands known for their incredibly fine underwater scenery. These islands are, therefore, a diver's paradise, having some of the finest diving spots in the world.

Highlights: One can dive or snorkel within the reef amidst multi-colored coral and marine life. Underwater visibility of this place is very high, allowing perfect views of various fish, manta rays, and even whale sharks. On land, you will find beautiful beaches with white sand and lush forests.

Tips: The Similan Islands are a protected national park, and access is closed during the monsoon season, May to October. Be sure to visit during the dry season for the best experience. Joining a liveaboard diving tour will also allow one to dive at some of the more remote dive sites.

Koh Lanta

Overview: Koh Lanta is an island that offers the right amount of relaxation and a nice serving of activity. With its long, sandy beaches, crystal-clear waters, and genuinely laid-back atmosphere, it's an ideal stopover to unwind after roaming around the more touristy spots.

Highlights: Every beach on the island, from lively Klong Dao Beach down to secluded Bamboo Bay, is worth visiting. Stroll along wooden piers in Old Town and enjoy fresh seafood at waterfront eateries. For some adventure, hire a scooter and make your way around the rugged interior of the island, or take a snorkeling day trip to the nearby Koh Rok.

Tips: Koh Lanta is less developed than many of the other islands, which is a good part of its charm. There are still plenty of accommodation options available, from budget bungalows to five-star resorts. Be sure to visit the island during the dry season, November to April for good weather.

Koh Lipe

Overview: Nicknamed "Maldives of Thailand," Koh Lipe is a small island near the Malaysian border. It boasts turquoise waters, white-sand beaches, and very vibrant coral reefs.

Highlights: Have a leisurely day at Pattya Beach, Sunrise Beach or Sunset Beach, each having its own atmosphere. Explore the waters offshore, snorkeling or diving among some of the most varied marine life in Thailand. In the evening, have a stroll up the walking street, which is a melange of restaurants, bars and shops.

Tips: Koh Lipe is quite isolated; therefore, this island should be visited by people looking for a more peaceful stay. Peak season does get crowded, so make sure to book your accommodation in advance. Be prepared to have a longer travel time since the best access to the island is by ferries from Pak Bara or even Langkawi, Malaysia.

Koh Yao Yai and Koh Yao Noi

Overview: These islands are located about halfway between Phuket and Krabi and offer the best retreat from most of the tourist spots. These islands are just right for people who want to experience local life and nature.

Highlights: Ending beaches, mangrove forests, rubber plantations. Hire a bicycle or a scooter to be free to chart your own pace around these islands. In contrast to Koh Yao Noi, which has more development and different types of accommodation, Koh Yao Yai is wilder, especially for those in search of solitude. Not to forget, take one day to trip to Phang Nga Bay, famous for its dramatic limestone karsts that rise like giants from emerald-green waters.

Tips: These islands are relatively undeveloped, so don't come expecting a glittering night scene. It's all about the relaxed atmosphere, hospitality of the locals, and the beauty of nature. This is an excellent place for a day-trip excursion off Phuket or Krabi or for a longer stay for those who wish to avoid the crowds.

How to Plan Your Island Hopping Adventure

Choosing the Right Season: The best time to explore the Andaman coast is during the dry season, from November to April. Weather conditions are perfect: the sea is calm, and blue skies prevail—ideal weather for boat trips and a variety of outdoor activities. The monsoon period, from May to October, guarantees rough seas and heavy rainfall, so it's better to avoid island hopping during this period.

Getting Around: The Andaman coast is well-connected by ferries and speedboats. It is easy to hop from one island to the other. Phuket and Krabi are the primary entry points that enjoy regular boat services to the nearby islands. You can take a tour or rent a private boat for places that are far away.

Accommodation: Accommodation options range from budget hostels to luxury resorts. Much of the accommodation on the islands is available on the more popular islands, such as Phi Phi and Koh Lanta, with small islands like Koh Lipe and the Koh Yao islands offering less. Booking accommodation in advance is always a good idea, especially during peak season.

What to Pack: You'll want to travel light, but make sure you pack the most important items: swimsuits, sunscreen, a hat, a refillable water bottle, good pair of flip-flops or sandals, and some decent shoes if you plan on doing any hiking or general exploring around. If you plan on snorkeling and diving at all, you might want to bring your gear in, even though there are a lot of rentals around.

Respect the Environment: The beauty of the Andaman coast is part of its natural surroundings; do your part to help protect it. Ensure avoiding single-use plastics, proper waste disposal, care for marine life while snorkeling or diving, and respect the fact that many of these islands form part of national parks and their rules, as well as the local environment, too.
