Phuket: Thailand’s Tropical Paradise Island
Phuket stands as Thailand’s largest island, stretching 50km long by 20km wide in the Andaman Sea. Connected to the mainland by Sarasin Bridge, this 576 km² paradise has transformed from a tin-mining hub to Thailand’s premier beach destination.
You’ll find white-sand beaches along the western coast, with Patong, Karon, and Kata being the most popular. Bangla Road in Patong buzzes with nightlife, while Phuket Town offers quieter cultural experiences with its Chinese-Portuguese architecture. While enjoying these attractions, remember that Thailand is generally safe for travelers if you exercise normal precautions.
The international airport provides direct access from major cities worldwide.
Visit during November-April to avoid monsoon season. Beyond beaches, explore nearby Similan and Surin Islands for diving, take a Thai cooking class, or witness the extreme rituals of the annual Vegetarian Festival.
Luxury resorts, medical tourism facilities, and Muay Thai camps cater to diverse interests. The devastating 2004 Indian Ocean tsunami caused significant damage to the island and claimed thousands of lives, but Phuket has since rebuilt into an even more vibrant destination.
Krabi’s Railay Beach: A Hidden Gem Only Accessible by Boat
Unlike most Thai beach destinations, Railay Beach exists in splendid isolation, completely cut off from mainland Krabi by towering limestone cliffs that make road access impossible. You’ll arrive by longtail boat from Ao Nang (15 minutes, 200 THB round-trip) or Krabi Town.
The peninsula features four distinct beaches: stunning Railay West with white sand, mangrove-lined Railay East, cave-dotted Phra Nang, and climber-favorite Tonsai. Visiting Phra Nang Cave reveals curious offerings in the form of carved wooden phalluses left by locals seeking fertility blessings.
Beyond sunbathing, you can rock climb 100+ meter cliffs, kayak through hidden lagoons, hike to viewpoints, or explore caves with stalactites. While more affordable than Koh Samui, prepare to pay premium prices for restaurants and accommodations due to the beach’s isolation and popularity.
Pack light as only footpaths connect beaches. Bring cash (ATMs are scarce), book accommodation in advance, and check tide schedules for beach activities.
Koh Pha-Ngan: More Than Just Full Moon Parties
While Railay Beach offers isolated cliff-surrounded beauty, Koh Pha-Ngan presents a completely different island experience in the Gulf of Thailand. Located just 15km from Koh Samui, this 125km² island balances famous nightlife with natural tranquility.
Beyond Haad Rin’s legendary Full Moon Parties, you’ll discover secluded beaches like Thong Nai Pan and Bottle Beach. The island’s interior features dense evergreen forest covering 52% of the land, with hiking opportunities to Khao Ra’s 635m peak. The island’s name derives from “ngan,” meaning sandbar, referencing the numerous offshore sandbars surrounding the island.
Accessible via speedboat from Koh Samui (30 minutes) or ferry from Surat Thani, the island has evolved beyond party tourism. A growing wellness scene with yoga retreats offers alternatives to nightlife. Visitors seeking more beach destinations might also explore Phuket Island for its stunning coastal highlights and diverse attractions.
The 10,000 permanent residents maintain traditional fishing and coconut farming alongside tourism, creating an authentic Thai experience with international influences.
Khao Lak: Serene Beaches and Family-Friendly Luxury
Just a short drive north of bustling Phuket lies Khao Lak, a stretch of Thailand’s Andaman coastline that offers pristine beaches without the crowds. This tranquil destination features numerous public beaches with gentle slopes perfect for families.
You’ll find 154 hotels with over 10,600 rooms, including luxury resorts like JW Marriott. Nang Thong Beach in Bang La On village forms the area’s center, while Khuk Khak Beach attracts visitors with its white sand and swimmable waters.
After days spent swimming and beach walking, enjoy fresh seafood at beachfront restaurants as the sun sets. For adventure, book diving excursions to nearby marine parks. Khao Lak stands out among top beach destinations in Thailand for its perfect combination of natural beauty and accessibility.
Khao Lak strikes the perfect balance—maintaining its unspoiled charm while providing comfortable amenities for travelers seeking peaceful beach experiences. Located in Phang Nga Province, about 60 km north of Phuket, the area encompasses approximately 25 km of beautiful coastline along the Andaman Sea.
Koh Samui: The Perfect Blend of Beach Life and Nightlife
You’ll find everything from the bustling Chaweng Beach with its water sports to the more secluded Silver Beach, ideal for snorkeling. Don’t miss Ang Thong National Marine Park for kayaking and hiking day trips.
After sunset, the island transforms. Head to Ark Bar Beach Club for fire shows, sip cocktails at beachfront Coco Tam’s, or dance at Green Mango Club with international DJs. Koh Samui has become one of Thailand’s top tourism destinations, contributing significantly to the country’s impressive 35% growth in international arrivals in 2024.
Accommodation options span from luxury Conrad and Four Seasons resorts to budget-friendly hotels in Lamai. The island’s unique appeal comes from its perfect balance of natural beauty and modern amenities that cater to all types of travelers.
Visit between December and April for most favorable weather while exploring traditional Thai culture at Wat Plai Laem between beach sessions.
The Unspoiled Beauty of Trang Islands
Far from the crowded shores of Thailand’s more famous destinations, the Trang Islands offer a glimpse into what Thai beaches were like before mass tourism arrived. Located in southern Thailand between Krabi and Satun, this archipelago of 47 islands remains invigoratingly undeveloped.
Discover Thailand’s untouched paradise where pristine beaches and minimal development offer an authentic escape from tourist crowds.
You’ll discover diverse landscapes from pristine beaches to dramatic cliffs and lush mangrove forests. Island hopping to Ko Libong, Ko Sukorn, or Ko Lao Liang reveals tranquil shores where you might spot dugongs or sea turtles in their natural habitat. Don’t miss the breathtaking Emerald Cave on Koh Muk, where a hidden beach awaits inside limestone cliffs.
While accommodation ranges from budget to luxury, the infrastructure remains minimal compared to Thailand’s popular beach towns. This unspoiled quality is precisely what makes Trang special.
You’ll enjoy snorkeling, kayaking, and longtail boat trips without battling crowds, experiencing Thailand’s natural coastal beauty in peaceful surroundings. For more adventure, consider a day trip to Krabi Province, where limestone karsts and hidden lagoons create some of Thailand’s most dramatic coastal scenery.
Koh Lanta: Laid-Back Charm Off the Beaten Path
Between the bustling Phi Phi Islands and Thailand’s mainland lies Koh Lanta, an archipelago where time seems to slow down deliberately. The main island, Ko Lanta Yai, spans 81 km² in the Strait of Malacca and belongs to Krabi Province.
You’ll discover a 60.6 km coastline dotted with tranquil beaches like Khlong Dao, Klong Khong, and Kantiang Bay, all known for their unspoiled beauty and turquoise waters. The island’s southern tip houses Mu Ko Lanta National Park, a haven for diverse marine life and wildlife. Many locals speak a distinctive Southern Thai dialect that adds to the authentic cultural experience.
What makes Koh Lanta special is its cultural mosaic of Buddhist and Muslim communities. Unlike Phuket’s popularity, Koh Lanta offers a more serene and less commercialized atmosphere for travelers seeking authenticity. Once called “Pulao Satak,” the island maintains its traditional fishing practices and crafts while embracing eco-friendly tourism initiatives that protect its natural splendor.
Similan Islands: A Diver’s Dream Destination
While Koh Lanta offers laid-back coastal charm, the Similan Islands present an underwater paradise that ranks among Thailand’s most spectacular marine environments. This archipelago of 11 granite islands sits 70km from mainland Thailand in the Andaman Sea.
Escape Koh Lanta’s shores to discover the Similan Islands—Thailand’s underwater jewel waiting beneath the Andaman waves.
You’ll find exceptional visibility (20-30 meters) and water temperatures between 27-30°C during the October to May season. The diverse underwater landscape features granite boulders, caves, and healthy coral reefs supporting over 500 fish species and marine life including manta rays and whale sharks. Unlike the overwater bungalows found in the Maldives, Thailand’s marine attractions focus on underwater exploration and natural preservation.
Access is primarily via speedboat from Phuket (1.5 hours) or through multi-day liveaboard trips. There’s no on-island accommodation, and all visitors must pay a 500 THB daily permit fee. For conservation purposes, Ko Huyong and several other islands are off-limits to travelers to protect vital turtle nesting sites.
Conservation measures include no-take zones, visitor caps, and a plastic-free policy.
Koh Phi Phi: Postcard-Perfect Beaches and Crystal Waters
Nestled in Thailand’s Krabi Province amid the azure Andaman Sea, Koh Phi Phi delivers some of Thailand’s most breathtaking coastal scenery. Made famous by the film “The Beach,” this island paradise attracts over a million visitors yearly who come for its pristine white sands and vibrant marine life. While Koh Phi Phi is renowned, travelers seeking a more secluded paradise might consider Koh Lipe’s beaches as an equally stunning alternative.
You’ll find accommodation options ranging from budget-friendly hostels to luxury resorts. The island is easily accessible by ferry from both Phuket and Krabi, with December to April offering ideal weather conditions. Visitor numbers to the Phi Phi Islands National Park have shown significant growth over the past decade, according to the Department of National Parks, Wildlife and Plant Conservation.
Must-do activities include:
- Swimming in the turquoise waters of Maya Bay
- Exploring the secluded tranquility of Nui Beach

After sunset, head to Loh Dalum Beach for the island’s famous nightlife scene.
