2. Geography of Thailand

Located in the center of mainland Southeast Asia, Thailand shares borders with Myanmar to the west and northwest, Laos to the north and northeast, Cambodia to the southeast, and Malaysia to the south. The country boasts a long coastline stretching along the Gulf of Thailand to the east and the Andaman Sea to the west, offering countless stunning beaches and island getaways. With a total area of approximately 513,120 km², Thailand features a diverse topography that ranges from forested mountains to fertile plains and tropical coastlines.

Terrain
Thailand’s landscape is divided into four distinct regions:

• The Northern Highlands, marked by forested mountains and cool valleys, are home to Thailand’s highest peak, Doi Inthanon (2,565 meters). This region is known for its hill tribes, trekking routes, and misty scenery.
• The Central Plains, often referred to as the “rice bowl of Asia,” are fertile lowlands nourished by the Chao Phraya River. This area is the heart of Thailand’s agriculture and economic activity, and includes the bustling capital, Bangkok.
• The Northeastern Plateau (Isan) features arid, undulating terrain and a distinct culture influenced by nearby Laos. Though drier than other regions, it is rich in historical ruins and traditional villages.
• The Southern Peninsula, extending between two seas, is dotted with limestone cliffs, coconut groves, rainforests, and idyllic islands. This region is famous for world-class beaches, marine biodiversity, and dramatic coastal scenery.

Climate
Thailand has a tropical climate with three distinct seasons:

• Hot Season (March to June) – Temperatures can soar above 35°C, especially in inland areas.
• Rainy Season (July to October) – Dominated by the southwest monsoon, this period brings frequent rainfall and high humidity.
• Cool Season (November to February) – Marked by lower humidity and pleasant temperatures, this is the most popular time for tourism.

Average annual temperatures range from 24°C to 34°C, and annual rainfall varies by region, with the south receiving the most precipitation.

Ecosystems
Thailand is home to an extraordinary range of ecosystems, from dense evergreen forests to coral reefs and mangrove swamps. The country supports over 15,000 species of plants, 1,000 species of birds, and hundreds of mammals, including elephants, gibbons, and the elusive Malayan tapir.

Thailand’s national parks and protected areas—such as Khao Yai National Park, Erawan Falls, and Similan Islands Marine Park—offer critical habitats for wildlife and serve as major eco-tourism destinations. Marine biodiversity is especially rich along the Andaman Sea coast, drawing divers from around the globe.

With its varied landscapes, abundant biodiversity, and year-round natural beauty, Thailand offers endless opportunities for adventure, discovery, and sustainable travel.

Here are some of the best places to visit, each offering its own unique charm.

Bangkok – The Vibrant Capital

A heady mix of tradition and modernity, Bangkok is Thailand’s fast-paced heart. Grand palaces, bustling street markets, and a legendary food scene make this city a must-visit.

Surrounded by ancient city walls and moats, it’s a gateway to more than 300 temples, including the famous Wat Phra That Doi Suthep perched on a mountaintop. The city is also a hub for Thai cooking classes, elephant sanctuaries, and weekend markets. Come in November to witness the magical Yi Peng Lantern Festival, when thousands of lanterns are released into the sky.

Ayutthaya – Ruins of a Glorious Past

Once the capital of the Siamese Kingdom, Ayutthaya is now a UNESCO World Heritage Site known for its impressive temple ruins, crumbling statues, and atmospheric charm. A day trip from Bangkok lets you wander through historical sites like Wat Mahathat, where a Buddha head entwined in tree roots draws visitors and photographers alike.

Phuket – The Island That Has It All

Thailand’s largest island, Phuket, is a destination that caters to all types of travelers. Whether you're seeking luxury resorts, vibrant nightlife, or quiet beaches, you'll find it here. Patong Beach is famous for its party scene, while Kata, Karon, and Nai Harn offer more peaceful settings. Day trips to nearby islands like James Bond Island or Similan Islands for snorkeling and diving are also popular.

Pai – A Bohemian Retreat in the Mountains

Tucked away in a lush valley near the Myanmar border, Pai is a favorite among backpackers and nature lovers.

Motorbike through rice paddies, explore Pai Canyon, and watch the sun set over the mountains—it’s slow travel at its best.

Koh Samui – Island Luxury and Laid-back Charm

Located in the Gulf of Thailand, Koh Samui is famous for its palm-fringed beaches, upscale resorts, and lush coconut groves. Chaweng Beach buzzes with nightlife, while Lamai offers a quieter alternative. Visit Big Buddha Temple, hike to waterfalls, or take a boat to the nearby Ang Thong Marine Park for kayaking and snorkeling.

Chiang Rai – Temples and Art in the Far North

Often overshadowed by Chiang Mai, Chiang Rai deserves attention for its surreal and artistic landmarks. The White Temple (Wat Rong Khun) is a dazzling blend of tradition and contemporary art, while the Blue Temple and Black House add to the city’s mysterious and creative appeal. It’s also a gateway to the Golden Triangle region, where Thailand, Laos, and Myanmar meet.

Sukhothai – The Birthplace of Thai Civilization

6. National Dishes You Can’t Miss in Thailand

Thai cuisine is world-famous for its vibrant flavors, fresh ingredients, and perfect harmony of sweet, sour, salty, and spicy notes. Eating your way through Thailand isn’t just a pleasure—it’s a cultural experience. From humble street carts to elegant restaurants, these iconic dishes capture the essence of Thai cooking. Here are the must-try national dishes you shouldn't miss:

Pad Thai – Thailand’s Signature Stir-Fried Noodles

Perhaps Thailand’s most internationally recognized dish, Pad Thai is a delicious combination of stir-fried rice noodles, egg, tofu or shrimp, bean sprouts, peanuts, and lime. Sweet tamarind sauce gives it a distinct tang, while the optional chili flakes let you dial up the heat to your liking. Found everywhere from street stalls to upscale bistros, Pad Thai is a classic you’ll want to enjoy more than once.

Tom Yum Goong – Spicy and Sour Shrimp Soup

A bowl of Tom Yum Goong is a masterclass in Thai flavor balance. Made with shrimp, lemongrass, galangal, kaffir lime leaves, chili, and lime juice, this soup delivers a spicy, sour punch that’s incredibly refreshing. Served clear or with a dash of coconut milk for richness, it’s a staple in Thai households and restaurants alike.

Green Curry (Gaeng Keow Wan)

Green curry is one of Thailand’s most beloved curries—spicy, creamy, and deeply aromatic. Cooked with green chili paste, coconut milk, Thai basil, and tender slices of chicken or beef, it’s typically served with jasmine rice or rice noodles. The bright green color comes from fresh green chilies and herbs, giving it both heat and freshness.

Som Tum – Spicy Green Papaya Salad

Hailing from the northeast (Isan region), Som Tum is a fiery, tangy salad made from shredded green papaya, tomatoes, green beans, peanuts, dried shrimp, and chili, all pounded together in a mortar. The flavor is intense—sour, salty, spicy, and just a hint of sweetness—making it a favorite street food for locals and adventurous eaters.

Massaman Curry – Thai-Muslim Comfort Food

A mellow and hearty dish influenced by Indian and Muslim cuisine, Massaman Curry features tender chunks of beef or chicken simmered in coconut milk with cinnamon, cardamom, potatoes, and roasted peanuts. Rich and slightly sweet, it’s often served with rice and is ideal for those who prefer a milder curry.

Khao Pad – Thai Fried Rice

Simple but satisfying, Khao Pad is Thailand’s take on fried rice. It usually includes egg, garlic, onions, vegetables, and your choice of protein like shrimp, chicken, or crab. It’s often garnished with cucumber slices, lime wedges, and prik nam pla (a spicy fish sauce condiment), offering a perfect balance of comfort and flavor.

Pad Kra Pao – Holy Basil Stir-Fry

A popular Thai lunch dish, Pad Kra Pao features minced meat (usually pork or chicken) stir-fried with garlic, chili, and holy basil, then served over rice and topped with a crispy fried egg. It’s fiery, aromatic, and widely considered the go-to “fast food” for locals.

Mango Sticky Rice (Khao Niew Mamuang)

Thailand’s most famous dessert, Mango Sticky Rice, pairs sweet, ripe mango slices with sticky rice soaked in sweetened coconut milk. The contrast of warm, creamy rice with cold, juicy mango is pure indulgence. It’s seasonal (best during mango season, April–June) but available year-round in most cities.
