Discover Thailand Vietnam and Cambodia trip

Southeast Asia is a land of vibrant cultures, ancient wonders and unforgettable flavors — and no trio of countries captures this essence more perfectly than Thailand, Vietnam and Cambodia. Here’s a glimpse into what makes this journey truly magical.

Top activities in Thailand you shouldn’t miss

Immerse in Bangkok’s Royal grandeur

Begin your journey in Bangkok with a visit to the Grand Palace and Wat Phra Kaew. The palace complex dazzles with intricate mosaics, golden spires and centuries-old architecture. Don’t miss Wat Pho nearby — home to a colossal reclining Buddha and a traditional Thai massage school. These landmarks reflect the soul of Thai Buddhism and are essential to understanding the country’s spiritual heart.

Dive into Thai cuisine with a cooking class

Food is a highlight of any Thailand Vietnam and Cambodia trip and what better way to explore Thai flavors than by learning to cook them? In Chiang Mai or Bangkok, join a hands-on cooking class where you’ll visit local markets, select fresh herbs and prepare classics like green curry, mango sticky rice and spicy papaya salad. It’s both fun and delicious.

Experience local life at a floating market

Take a long-tail boat through the maze-like canals of a traditional floating market such as Damnoen Saduak or Amphawa. Vendors sell everything from tropical fruits to coconut ice cream directly from their boats. It’s a vivid, colorful and distinctly Thai experience that’s both a shopping trip and cultural adventure.

Island hop in the Andaman Sea

Thailand’s southern coast is famous for its postcard-worthy islands. From Krabi or Phuket, embark on a speedboat tour to explore Phi Phi Islands, Maya Bay and James Bond Island. Snorkel over coral reefs, relax on white sand beaches and swim in hidden lagoons. These islands are a paradise for beach lovers and photographers alike.

Rejuvenate with a traditional Thai massage

After a full day of exploring, there’s nothing better than a traditional Thai massage. Available at local spas and wellness retreats across the country, this form of bodywork blends acupressure, stretching and rhythmic movement — perfect for recharging before your next destination.

Top activities in Vietnam you shouldn’t miss

Sail through the mystical Ha Long Bay

Ha Long Bay in northern Vietnam is a natural wonder of towering limestone islands rising from emerald waters. A must-do activity is an overnight cruise, where you can kayak through caves, visit floating fishing villages and enjoy sunset dinners on deck. The surreal scenery makes this one of the most iconic highlights of any trip to Thailand Vietnam and Cambodia.

Wander the timeless streets of Hoi An

Step back in time in the lantern-lit town of Hoi An. Explore ancient Chinese temples, French colonial houses and the iconic Japanese Covered Bridge. The town is also famous for custom-tailored clothing — you can get a suit or dress made in 24 hours. Don’t leave without trying local dishes like Cao Lau or white rose dumplings.

Taste street life in Vietnam’s big cities

In Hanoi and Ho Chi Minh City, life happens on the streets. Join the locals on tiny plastic stools for bowls of steaming pho or crispy banh mi. 

• In Hanoi, stroll around Hoan Kiem Lake and explore the Old Quarter’s maze of shops and cafes. 
• In Ho Chi Minh City, take a Vespa tour at night or visit the War Remnants Museum to gain insight into the country’s recent past.

Cruise the waterways of the Mekong Delta

Down in southern Vietnam, the Mekong Delta offers a slower pace of life. Glide through narrow canals in a wooden sampan, visit traditional craft villages, explore famous floating markets and sample coconut candies and snake wine. This region is rich in agriculture and tradition, giving you a glimpse into Vietnam’s rural soul.

Trek among rice terraces in Sapa

If you love nature and adventure, head north to Sapa. Here, dramatic rice terraces stretch across the hills and ethnic minority villages like the Hmong and Red Dao welcome visitors into their homes. Multi-day treks offer a chance to connect deeply with the land and its people while enjoying cooler mountain air.

Top activities in Cambodia you shouldn’t miss

Watch the sunrise at Angkor Wat

Angkor Wat is the crown jewel of Cambodia and no trip to Thailand Vietnam and Cambodia is complete without seeing it. Wake up early to watch the sun rise behind its iconic towers. Then, spend the day exploring nearby temples like Ta Prohm, where roots grow through stone and Bayon, with its many smiling stone faces.

Explore Cambodia’s past in Phnom Penh

For a deeper look at Cambodia’s complex history, visit the Tuol Sleng Genocide Museum and the Killing Fields. Though emotionally intense, these sites offer important context and honor the resilience of the Cambodian people. Finish the day with a visit to the Royal Palace and Silver Pagoda to appreciate the nation’s cultural heritage.

Float through villages on Tonle Sap Lake

Just outside Siem Reap lies Tonle Sap, Southeast Asia’s largest freshwater lake. Hop on a boat to see floating homes, schools and markets that rise and fall with the water level. The communities here live in harmony with nature and give visitors a rare glimpse into life on the water.

Relax on the shores of Koh Rong

Cambodia’s islands remain under the radar — and that’s part of their charm. Koh Rong and its quieter sister Koh Rong Samloem offer powdery beaches, crystal-clear waters and bioluminescent plankton you can swim with at night. It’s the perfect place to slow down and reflect on your journey.

Respect local customs

• In Thailand, greet others with a “wai” by pressing your palms together. Always dress modestly when visiting temples, covering shoulders and knees. Never touch anyone’s head as it is considered sacred. Avoid pointing your feet at people or religious statues, as feet are seen as unclean.

• In Vietnam, take off your shoes before entering someone’s home or certain shops. Address older people respectfully using formal titles plus their first names. When visiting temples, dress conservatively and speak quietly. Keep your voice low in public places to maintain harmony.

• In Cambodia, greet people with the “sampeah” gesture — palms pressed together and a slight bow. Dress modestly when visiting temples or sacred sites. Always ask permission before photographing locals, especially monks or during ceremonies. Like Thailand, do not touch people’s heads or point your feet toward others or religious objects.

A Thailand Vietnam and Cambodia trip is more than just a vacation — it’s a journey through centuries of culture, flavors and unforgettable landscapes. Each destination offers its own unique charm, yet together they form a seamless and enriching travel experience.
