Top places to visit in Thailand
Bangkok

Known locally as Krung Thep, this sprawling metropolis sits in the Chao Phraya River delta in central Thailand. As the nation’s capital and largest city, it dwarfs other urban centers in both size and economic importance. The city’s roots trace back to a small trading post during the Ayutthaya era, evolving into a vibrant hub that defines the country’s modern identity. Visitors find a dense, energetic environment where history meets contemporary life. Its status as an extreme primate city means it concentrates a massive share of the national population, creating a dynamic atmosphere that is central to understanding Thai culture and commerce.
Chiang Mai

Located 700 kilometers north of Bangkok in the mountainous Thai highlands, Chiang Mai serves as the capital of its province and the largest city in northern Thailand. The historic heart of the city is a compact square area, roughly one mile by one mile, bordered by remnants of ancient red brick walls and a surrounding moat. This old town core is distinct from the broader metropolitan region, which includes surrounding districts like Hang Dong, San Sai, and Saraphi. Travelers exploring the city will find a blend of historical architecture and natural mountain scenery, offering a different pace and landscape compared to the southern lowlands.
Phuket

Phuket is Thailand’s largest island, situated off the west coast in the Andaman Sea. The province includes the main island plus thirty-two smaller islands, creating a diverse archipelago for exploration. Connected to the mainland by the Sarasin Bridge to the north, it lies near Phang Nga province, with Krabi situated to the east across the bay. Historically, this strategic location placed the island on a major trading route between India and China. Today, visitors enjoy the coastal setting and the unique geography of the region, which offers a mix of beach relaxation and island-hopping opportunities in the surrounding waters.
Pattaya

Situated on the east coast of the Gulf of Thailand, Pattaya is the largest city in Chonburi province and lies approximately 150 kilometers southeast of Bangkok. It functions as a special local government organization area within Bang Lamung district, covering specific sub-districts like Nong Prue and Na Klua. The city has expanded into adjacent areas, making it a significant urban center in the region. For travelers, Pattaya offers a coastal destination close to the capital, providing easy access to the Gulf’s beaches and a distinct urban environment that serves as a gateway to the eastern part of the country.
Khao Yai National Park

Thailand’s first national park, established in 1962, Khao Yai stands as a cornerstone of the country’s conservation history. Named after a former local district, this expansive protected area is the third largest in the nation and was later recognized as a UNESCO World Heritage Site in 2005. As part of the Dong Phayayen–Khao Yai Forest Complex, it offers visitors a chance to explore diverse ecosystems that have been preserved since the mid-twentieth century. The park’s legacy, shaped significantly by early conservation efforts, makes it a vital destination for nature enthusiasts seeking to experience the rich biodiversity of central Thailand’s mountainous terrain.
Krabi

Situated on the west coast of southern Thailand, Krabi serves as the administrative heart of its province. The town is defined by the convergence of the Krabi River and Phang Nga Bay, creating a dramatic landscape of water and limestone. Located roughly 650 kilometers south of Bangkok, this area has a history stretching back to the late eighteenth century, when an elephant kraal was established under royal order. Today, the local economy is heavily driven by tourism, attracting travelers who come to explore the scenic beauty of the bay and the surrounding coastal environment. It remains a key gateway for those exploring the rugged southern coastline.
Khao Lak

Originally a small village in Phang Nga Province, Khao Lak has evolved into a popular tourist destination centered around its beaches. The name translates to Main Mountain, referring to a peak that ancient seafarers used as a landmark to navigate safely into the harbor at Thap Lamu. Today, tour operators use the name to describe a cluster of nearby villages that have developed to cater to visitors. Located south of the mountain, the area features the original Hat Khao Lak beach. The surrounding region is part of a hilly landscape with peaks reaching over 1,000 meters, offering a mix of coastal relaxation and natural scenery for travelers.
Historical and cultural sites in Thailand
Ayutthaya Historical Park

This park preserves the ruins of Ayutthaya, a city founded by King Ramathibodi I in 1351. However, evidence suggests the area was inhabited much earlier during the Mon Dvaravati period. Around 850 AD, Khmer occupiers established a stronghold here, naming it Ayodhya after a sacred Hindu city in India. Today, visitors can explore the extensive remains of this historic capital, which reflect centuries of cultural and political evolution in the region.
Historic Town of Sukhothai and Associated Historic Towns

Recognized as a UNESCO World Heritage Site, this collection includes Sukhothai, Kamphaeng Phet, and Si Satchanalai historical parks. Together, they preserve the remains of the three main cities of the Sukhothai Kingdom, which flourished during the 13th and 14th centuries. Historians view this kingdom as the first of the Thai kingdoms, making these sites essential for understanding the origins of Thai culture, architecture, and statehood in the region.
Wat Arun

Known as the Temple of Dawn, this Buddhist temple sits on the west bank of the Chao Phraya River in Bangkok. It is named after the Hindu god Aruṇa, who represents the radiations of the rising sun. The structure features a unique fusion of Indian influences, blending Hindu and Buddhist symbolism with traditional Siamese identity. Its distinctive design makes it a prominent landmark in the Bangkok Yai district.
Ban Chiang
Located in Udon Thani province, this archaeological site has been a UNESCO World Heritage Site since 1992. Discovered in 1966, it initially drew attention for its ancient red-painted pottery. Beyond its artistic significance, Ban Chiang provides crucial evidence of early agriculture in the region. The pottery and other artifacts depict a strong cultural influence, offering insights into the lives of early inhabitants in northeastern Thailand.
Phra Nakhon Khiri Historical Park
Situated on a 95-meter hill overlooking Phetchaburi, this park is locally known as Khao Wang, or hill with palace. The name Phra Nakhon Khiri translates to holy city hill. The site features three building groups across the peaks: a palace on the western peak, a large chedi called Phra That Chom Phet on the central peak, and the royal temple Wat Phra Kaeo on the eastern peak.

Stay connected in Thailand and avoid roaming bills
Using your home carrier abroad can get expensive fast: daily roaming passes and out-of-bundle data are billed at rates most people only see after they get home. A travel eSIM avoids that. It is a data plan you install on your phone before the trip, so you land already online for maps, ride apps and messaging, while your normal number stays active for calls and codes.
- Install it at home over Wi-Fi, then switch it on when you arrive. The validity starts on first connection in Thailand, not at purchase.
- Local networks on our Thailand plans: TrueMove H 5G, DTAC 5G.
- It is data only, so your own SIM keeps your number. Turn Data Roaming on for the eSIM line.
- Your phone must support eSIM and be carrier-unlocked (dial *#06# and look for an EID).
