Things to Do in Thailand 18 Days

Visit Temples and Pagodas

The Grand Palace, Bangkok

With over 40,000 temples, choosing which ones to visit in Thailand can be a daunting task. While the Grand Palace and Wat Pho in Bangkok are often recommended, many other temples across the country could leave a lasting impression. For instance, in Chiang Rai’s northern town, Wat Rong Khun, known as the “White Temple,” captivates with its “bridge of rebirth” over a symbolic “lake” of hands depicting human suffering. Heading south near Pattaya, the Sanctuary of Truth is an awe-inspiring wooden structure, showcasing intricate carvings made with traditional methods. In Phetchabun, bordering the North and Northeast, Wat Phra Thad Son Kaew stands out with its unique Buddha statues reminiscent of Russian nesting dolls, set against a backdrop of striking mountains and Gaudi-style mosaics.

Relax on Beautiful Beaches



Thailand is famous worldwide for its breathtaking islands, characterized by lush greenery and crystal-clear, celadon waters. Phuket, the country’s largest and most popular island, serves as the perfect gateway to this tropical paradise. From Phuket’s two bustling marinas, visitors have the opportunity to charter a boat and explore the wonders of the Andaman Sea.

Among these is the famous Ko Khao Phing Kan, better known as James Bond Island, which gained fame in the 1974 movie “The Man With a Golden Gun.” This island stands out as a spectacular limestone karst, rising dramatically from the sea and topped with verdant foliage, resembling a natural exclamation point amidst the serene beauty of Phang Nga Bay. This iconic landscape, along with the myriad of other stunning islands in the area, encapsulates the essence of Thailand’s coastal allure.

Go Shopping at Thailand’s Top Markets

Chatuchak Market, Bangkok

Thailand’s love for shopping is evident in its abundance of markets, each offering a unique experience, from early morning fruit markets to vibrant night ones and everything in between. In Bangkok, the 24/7 Flower Market stands out, offering a stunning array of flowers perfect for Instagram, set against the Chao Phraya River. Another gem in Bangkok is Or Tor Kor Market, celebrated for its traditional sweets and fresh produce, and highly regarded even by the most discerning locals.

In the North, Chiang Mai is famous for its Saturday and Sunday Walking Streets, but the Walking Street in Chiang Khan, along the Mekong River, offers an equally extensive and picturesque shopping experience. For those interested in crafts, Hua Hin’s Cicada Market is a treasure trove of art, clothing, and souvenirs, conveniently located near the beach.

For a more serene experience, the tree-lined Khlong Lat Mayom floating market, less touristy and only a short drive from Bangkok, offers a peaceful alternative to the bustling Chatuchak Market and the popular floating markets of Damnoen Saduak and Amphawa. Each market has its charm, but be prepared for crowds, especially during peak times.

Take a Hike Through National Parks & Forests

Pranburi Forest Park

Pranburi Forest Park

Thailand, often seen as a beach paradise, surprisingly offers a wealth of hiking opportunities for all skill levels. Near the resort town of Hua Hin, just 25km (15.5 miles) to the south, lies Pranburi Forest Park. Here, a 1km-long (0.6 mile) boardwalk meanders through mangrove forests and pine trees, perfect for a family-friendly stroll amidst nature.

In the northern region, close to Chiang Mai, the Buddha’s Footprint Trail extends for 13km (8 miles). This trail, favored by birdwatchers, showcases a rich diversity of wildlife and plants. A guide, which can be hired from the local Hmong villagers, is required for this scenic hike.

For those seeking a more thrilling adventure, Wat Phu Thok in Northeastern Bueng Kan, also known as the “Lonely Mountain,” offers a challenging climb. The ascent to the 359m-high (1,200ft) peak involves steps, carved paths, and wooden slats, designed to reflect the seven levels of nirvana. This hike is not just a physical challenge but also a spiritual journey, encouraging meditation and mindfulness with each step.

Sample Delicious Street Food in Bangkok

Bangkok’s street food scene, having bounced back from the economic downturn caused by COVID, is now buzzing with renewed energy. Key areas like the Old Town, Charoen Krung Road, Bantadthong Road, and around the Victory Monument are hotspots for authentic and delicious street fare.

The epicenter of this culinary richness is Chinatown, also known as Yaowarat, which is widely regarded as the birthplace of Thai street food and restaurants. Here, a fusion of Chinese-Thai cuisine, including dishes like oyster omelets, soup noodles, rice porridge, and black sesame-stuffed dumplings, entices visitors. At night, Yaowarat Road transforms into a vibrant, neon-lit buffet, offering an unforgettable roadside dining experience. However, it’s important to note that many street food stalls are closed on Mondays, so it’s advisable to check the availability of your preferred vendors in advance.

  • Don’t Touch Someone’s Head: The head is considered the most sacred part of the body in Thai culture.
