Many travellers seek out mysterious places in Indochina for their long histories and unusual features. This article outlines five well-known locations — Banteay Chhmar, Bagan, My Son, Vat Phou and the Plain of Jars — summarising what makes each site notable and offering practical advice for visiting.
What these mysterious places in Indochina are and why they matter
Across mainland Southeast Asia, a string of ancient monuments and megalithic sites survive as reminders of past kingdoms and cultures. Some were built by powerful empires as religious or administrative centres; others remain enigmatic because their original function is not fully understood. Together they form important archaeological and cultural landscapes that attract scholars and travellers alike.
These locations vary widely: palace-temple complexes with carved stone reliefs, dense plains dotted with megaliths, and former urban centres with thousands of religious structures. Many have endured periods of abandonment, later rediscovery by colonial or local investigators, and damage from conflict and the elements. Visiting these sites offers insight into regional history and ancient construction techniques, while also raising questions still under academic debate.
Key highlights of each site
Banteay Chhmar (Cambodia) is an extensive ruined city in the northwest of the country, close to the Thai frontier. Constructed in the late 12th to early 13th century under King Jayavarman VII, the complex includes a main temple surrounded by a broad moat, sculpted bas-reliefs and faces carved on towers reminiscent of other Khmer monuments. Bas-reliefs here depict historic conflicts and processions, and many Buddha images survived despite long periods of neglect and wartime disruption.
Bagan (Myanmar) occupies a broad plain that was the heart of a powerful kingdom between the 9th and 13th centuries. In its heyday thousands of temples, stupas and monasteries were built; today more than two thousand structures remain, offering expansive templescapes visible across the plain. The site developed as a major religious and learning centre attracting scholars and monks from across the region.
My Son Sanctuary (central Vietnam) preserves a group of Hindu temples erected by the Cham between roughly the 4th and 13th centuries. The buildings are notable for fired-brick construction and sandstone decorative carvings. Many structures were badly damaged in 20th-century conflict; a fraction of the original complex has survived, but those remaining illustrate Cham masonry and iconography.
Vat Phou (southern Laos) sits at the base of a sacred, phallic-shaped mountain and was built by Khmer artisans earlier than some famous Khmer monuments. Initial foundations date back many centuries; surviving architecture largely dates from the 11th to 13th centuries. The site has long associations with Shaivite worship and is set within a wider archaeological zone.
The Plain of Jars (northeast Laos) is a very different kind of site: thousands of carved stone jars, distributed across a plateau and dating to the Iron Age (roughly 500 BCE to 500 CE). The purpose of these large megaliths is contested; hypotheses include funerary use, food storage or ritual practices. Some jar sites were damaged during mid-20th-century conflicts and many areas remain affected by unexploded ordnance.
Practical tips for visiting these sites
Access and infrastructure vary hugely between sites. Bagan and My Son are established visitor attractions with facilities and multiple access options, while Banteay Chhmar and parts of the Plain of Jars are in more remote areas with limited services. Vat Phou is reachable from the Champasak area but still retains a quieter, rural character. Plan time for road travel and expect variable standards of signage and amenities.
Season and local climates affect comfort and visibility. In central Vietnam and southern Laos, the wet season brings heavier rain and heat, while Myanmar’s dry season is usually the most comfortable for long days of exploration. For regional climate planning see broader seasonal advice on Vietnam travel such as Vietnam in Summer.
- Book local guides where available — they provide historical context and help navigate sites safely.
- Carry water, sun protection and sturdy footwear; surfaces can be uneven and exposed.
- Check access information in advance: permits, visitor rules and opening seasons vary by site.
- In Laos, be aware that former conflict has left unexploded ordnance in parts of the Plain of Jars — follow local guidance and stick to cleared paths.
Cultural and historical context
Each site reflects different cultural histories and religious practices. Khmer temple complexes such as Banteay Chhmar and Vat Phou illustrate the reach and architectural capabilities of Khmer polities, including syncretic forms of Hindu and Buddhist worship. My Son represents the Cham civilisation with its own distinct blend of Indic-influenced art and engineering. Bagan was a major Buddhist learning centre with long-ranging cultural connections across South and Southeast Asia.
Many artistic and construction techniques at these locations remain subjects of research. For example, Cham bricks at My Son are noted for their precise fitting and durability without visible mortar; archaeologists continue to study manufacturing methods. Bas-reliefs across Khmer sites provide iconographic narratives of rulers, deities and historical events, while the Plain of Jars presents an unresolved prehistoric question about ritual or practical uses.
Who these places suit
These sites will appeal to travellers interested in archaeology, architectural history and regional cultures. Photographers and history enthusiasts often prioritise Bagan for landscape views and sunrises; those curious about megalithic mysteries or prehistory may focus on the Plain of Jars. Visitors looking for less frequented monuments may prefer Banteay Chhmar or Vat Phou, which generally receive fewer tourists than the most famous temples in the region.
Accessibility differs: Bagan and My Son are relatively easy to include on typical itineraries, while reaching Banteay Chhmar or the more remote jar sites requires more planning and longer travel times. If you need country-specific entry information before visiting Myanmar, consult the practical guidance on Myanmar tourist visa.
Comparisons and alternatives
When choosing between these destinations, consider historical period, type of remains, and travel difficulty. Bagan offers a concentration of Buddhist monuments and broad visual panoramas; My Son focuses on Hindu-Cham structures in a compact site; Vat Phou provides an older Khmer context with a distinctive mountain backdrop; Banteay Chhmar offers large-scale relief sculpture and a more secluded atmosphere; the Plain of Jars is a prehistoric megalithic landscape rather than a temple complex.
For travellers who prefer better visitor infrastructure, Bagan and My Son are convenient. Those seeking solitude or less-visited ruins should allow extra time for travel to Banteay Chhmar or Vat Phou. The Plain of Jars is unique in form and requires attention to safety and local travel conditions.

Frequently Asked Questions
Are these sites safe to visit?
Most sites are visited safely each year, but levels of infrastructure and safety differ. The Plain of Jars has areas affected by unexploded ordnance; visitors should follow cleared routes and local advice. Remote sites can have limited emergency services, so plan accordingly.
How much time should I allocate at each location?
Time needs depend on interest and travel pace. Bagan can occupy several days for temple photography and exploration; My Son is often visited as a half-day excursion from nearby coastal towns. Banteay Chhmar, Vat Phou and jar sites typically require more travel time and may be best visited as part of a multi-day regional itinerary.
Is a guide necessary?
Hiring a knowledgeable local guide enhances understanding of history, symbolism and on-site safety — particularly in less-developed areas. Guides can also assist with logistics and communicate with local communities.
When is the best time to travel to these sites?
Dry seasons are generally preferable for comfort and reliable access. Regional climates vary: central Vietnam and Laos have distinct wet seasons, while Myanmar’s dry season typically offers clearer weather. Check seasonal travel advice for the countries you plan to visit before booking.
Can I support local communities when visiting?
Yes. Buying locally made handicrafts, hiring local guides and using community-run services helps communities benefit from tourism. In some parts of Laos, artisans turn scrap metal from wartime debris into jewellery and household items — purchases there can support local livelihoods.
