Thailand

Temples, street food and island coasts

Thailand is wonderfully easy to enjoy and surprisingly easy to get wrong. The difference usually comes down to two choices: which island coast suits your travel dates, and how to balance city, culture and beach without spending the trip in transit.

Generally favorable seasons
November to March for most regions; the Gulf islands are often good from January to August
Suggested first-trip length
12 to 16 days for city, north and islands
Especially good for
Food, temples, beach resorts, wellness, families and first trips to Asia

Thailand has long been one of Asia's most visited countries, and for good reason: superb food, warm hospitality, beautiful temples, excellent resorts and good infrastructure. The classic first trip combines Bangkok, northern Thailand around Chiang Mai, and a beach stay. The key is matching the beach to the season, because Thailand's two coasts have different rainy seasons.

Why visit Thailand

  • Food. One of the world's great cuisines, with strong regional differences between Bangkok, the north and the south.
  • Temples and culture. The Grand Palace and Wat Pho in Bangkok, the old city temples of Chiang Mai and the contemporary White Temple near Chiang Rai.
  • Beaches and islands. Two distinct coastlines: the Andaman Sea (Phuket, Krabi) and the Gulf of Thailand (Koh Samui and neighboring islands).
  • Hospitality and wellness. Excellent resorts, spas and wellness retreats across a wide range of styles.
  • Ease. Good domestic flights and a well-developed tourism industry make Thailand a comfortable first destination in Asia.

Regions and places to explore

Bangkok

A city of grand temples, river life, markets, rooftop bars and some of Asia's most exciting restaurants. Staying near the Chao Phraya River makes it easy to explore the historic sights by boat.

Chiang Mai

Northern Thailand's cultural center, with a walled old city full of temples, craft villages, night markets and the mountain temple of Doi Suthep. Cooler in the winter months than the south.

Chiang Rai

Further north, known for the White Temple (Wat Rong Khun), the Blue Temple and the Golden Triangle, where Thailand, Laos and Myanmar meet along the Mekong.

Phuket

Thailand's largest island, on the Andaman coast, with a wide choice of beaches and resorts, Phuket Old Town's Sino-Portuguese architecture, and boat trips to Phang Nga Bay.

Krabi

Dramatic limestone cliffs and islands on the Andaman coast. Railay, reached only by boat, and the islands around Koh Phi Phi are among the most photographed landscapes in the country.

Koh Samui

The main island in the Gulf of Thailand, with resorts, quieter beaches and easy access to the Ang Thong National Marine Park. Its weather pattern differs from Phuket and Krabi.

Khao Sok

One of Thailand's oldest rainforests, with Cheow Lan Lake, floating lodges, jungle walks and wildlife. It sits conveniently between the Andaman coast and Koh Samui.

Beyond the classics

Ayutthaya's ancient capital, Kanchanaburi and the River Kwai, Hua Hin's royal seaside resort, and the quieter islands of Koh Lanta, Koh Yao Noi and Koh Kood.

Festivals

When to go

Thailand broadly has a cool, dry season (around November to February), a hot season (March to May) and a rainy season (around June to October). The Gulf of Thailand is the main exception: Koh Samui and its neighbors tend to be wettest from about October to December, and are often good when the Andaman coast is in its rainy season. Our guide to Thailand for first-time visitors explains how to plan around this.

RegionGenerally favorableWetter period
Bangkok and central ThailandNovember to FebruaryJune to October
Chiang Mai and the northNovember to FebruaryJune to October; March and April can be smoky from agricultural burning

How long to stay

For a first trip combining Bangkok, the north and a beach, allow 12 to 16 days. Two weeks typically means three nights in Bangkok, three or four in Chiang Mai (or split with Chiang Rai), and five or six on the coast. With a week, choose Bangkok plus one beach. Our article on Bangkok, Chiang Mai or Phuket compares the three main bases.

A sample journey

Our 14-day Thailand journey combines Bangkok, Chiang Mai and Chiang Rai with a beach finish, with alternative coasts depending on the season.

Practical considerations

  • Entry requirements. From September 15, 2026, Thailand revoked its 60-day visa exemption. According to the Thai Ministry of Foreign Affairs, US passport holders are on the list for the revised 30-day visa exemption for tourism. All non-Thai visitors must also complete the online Thailand Digital Arrival Card (TDAC) before arrival. Rules depend on your passport and purpose of travel, so check before booking.
  • Getting around. Domestic flights link Bangkok with Chiang Mai, Chiang Rai, Phuket, Krabi and Koh Samui. Private transfers are recommended between airports and resorts.
  • Temple etiquette. Cover shoulders and knees, remove shoes where indicated, and show respect toward images of the Buddha and the monarchy.
  • Health. Consult a travel health clinic or CDC guidance before departure, and use mosquito protection.
  • Sea safety. Red flags on Andaman beaches during the rainy season indicate dangerous currents; follow local advice.

Thailand's visa exemption period and arrival procedures have changed several times. Confirm current requirements with the Royal Thai Embassy in Washington, DC or the official Thai e-visa and immigration sites before travel.

Who Thailand suits

Thailand suits first-time visitors to Asia, families, honeymooners, food lovers and anyone who wants culture and beach in one trip. Travelers seeking remote, uncrowded beaches should choose islands and seasons carefully.

Pairing Thailand with other destinations

Vietnam and Cambodia are a short flight away. Thailand also makes a relaxing stopover on the way to or from Australia.
