Top 16 'Tomb-Raider-Tier' Forgotten Temples to Explore in Southeast Asia's Deepest Jungles
There's a feeling that every true traveler chases. It's that heart-thumping, goosebump-inducing moment when you step out of the dense, humid jungle and into a clearing, laying eyes on something ancient, silent, and utterly magnificent. It’s the feeling of discovering a place that time, and most of the world, has forgotten. It’s the whisper of a forgotten empire on the wind, the sight of colossal stone faces being reclaimed by strangler figs.
Forget the selfie sticks and tour bus crowds of Angkor Wat's sunrise. We're talking about the real deal—the kind of crumbling, vine-choked ruins that would make Lara Croft or Indiana Jones dust off their gear. These are the places that demand a bit more effort, a longer journey, and a thirst for genuine adventure. They are the hidden jewels scattered across the deep jungles and misty mountains of Southeast Asia, waiting for those willing to venture off the well-trodden path.
In this guide, I'm sharing my ultimate list of 16 "Tomb-Raider-Tier" temples. These aren't just tourist sites; they are experiences. They are the destinations that reward the intrepid with solitude, mystery, and a profound connection to the past. So, lace up your sturdiest boots, pack your sense of wonder, and let's go exploring.
1. Koh Ker, Cambodia
Long before Angkor was the seat of power, the Khmer empire was ruled from a remote, ambitious city called Koh Ker. For a few short decades, it was the capital, and its crowning glory is Prasat Thom, a stunning seven-tiered sandstone pyramid that rises 36 meters above the surrounding jungle. It looks more like a Mayan relic than a classic Khmer temple, and its raw, imposing presence is unforgettable.
While the main pyramid is the showstopper, the real magic of Koh Ker lies in exploring the dozens of smaller, satellite temples scattered throughout the forest. Many are little more than crumbling piles of laterite and sandstone, actively being consumed by the jungle. You can spend a full day here and feel like you’re the first person to rediscover these ruins, with only the sound of cicadas for company.
Pro-Tip: Hire a moto-driver or a 4x4 from Siem Reap for the day. It’s about a 2.5-hour drive each way. Go early to beat the heat and the few day-trippers who make the journey. Bring plenty of water and snacks, as facilities are minimal.
2. Beng Mealea, Cambodia
If there is one temple that perfectly embodies the “lost in the jungle” fantasy, it’s Beng Mealea. Located about 70km from Siem Reap, this sprawling 12th-century complex has been almost completely surrendered to nature. It hasn't been restored; instead, elevated wooden walkways have been built to allow visitors to navigate the chaos of collapsed galleries, tangled roots, and moss-covered stones.
Exploring Beng Mealea is less about appreciating intricate carvings (though they are there, if you look) and more about soaking in the atmosphere. You’ll be climbing over massive stone blocks, ducking under thick vines, and peering into dark, collapsed chambers. It’s a photographer’s dream and an adventurer’s playground, offering a visceral glimpse of what the first European explorers must have felt when they stumbled upon Angkor.
Pro-Tip: Combine a trip to Beng Mealea with Koh Ker for an epic day of temple exploration. Because of its raw state, sturdy, closed-toe shoes are a must.
3. Preah Khan of Kompong Svay, Cambodia
For the truly dedicated temple hunter, this is the holy grail. Not to be confused with the smaller Preah Khan at Angkor, this gargantuan complex is one of the most remote and least-visited major temple sites in Cambodia. Getting there is an adventure in itself, involving long, bumpy dirt roads that can become impassable in the wet season.
Your reward is near-total solitude in a complex larger than any single temple at Angkor. You can explore its crumbling gopuras, libraries, and central sanctuary with no one else around. The feeling of discovery here is palpable. It took me two full days to reach and explore Preah Khan of Kompong Svay, a journey that reminded me why I, Goh Ling Yong, started this blog in the first place—to chase these moments of pure, unadulterated discovery.
Pro-Tip: This is not a casual day trip. You'll need to arrange a serious 4x4 and an experienced driver from Siem Reap or Kampong Thom. Plan to stay overnight in a nearby village for the full experience.
4. Banteay Chhmar, Cambodia
Nestled near the Thai border, Banteay Chhmar is a colossal temple city built by the great King Jayavarman VII. Its most famous features are the enigmatic, multi-armed Lokeshvara reliefs carved into its outer walls, telling epic tales of ancient sea battles and mythical struggles. The temple is slowly being cleared and restored, but vast sections remain wild and untamed.
What makes Banteay Chhmar so special is the community-based tourism project that supports it. You can arrange to stay in a local homestay, eat traditional Khmer meals, and hire a village guide who will proudly show you the hidden corners of their ancestral temple. It's a sustainable way to experience one of Cambodia's greatest forgotten treasures.
Pro-Tip: The journey from Siem Reap takes about 3-4 hours. Plan to spend at least one night to fully appreciate the temple at sunrise and sunset, when the golden light on the carved faces is simply magical.
5. My Son Sanctuary, Vietnam
Hidden away in a lush valley surrounded by hills, the My Son Sanctuary was the spiritual and political heart of the ancient Champa Kingdom for over a thousand years. These unique, red-brick towers and sanctuaries are dedicated to the Hindu god Shiva and stand as a testament to a culture that is distinct from the neighboring Khmer.
Tragically, the site was heavily bombed during the Vietnam War, and you can still see massive craters dotting the landscape. This somber history adds a layer of poignant beauty to the ruins. Walking through the quiet, jungle-enshrouded complex feels like stepping into a different world, where the ghosts of an ancient civilization still linger.
Pro-Tip: My Son is an easy day trip from Hoi An or Da Nang. Visit early in the morning or late in the afternoon to avoid the midday heat and the largest tour groups.
6. Mrauk U, Myanmar
Imagine the temples of Bagan, but swap the dry plains for misty green hills and a far more remote location. That’s Mrauk U. This was once the capital of a powerful Arakanese kingdom, and its fortress-like stone temples are starkly different from the brick stupas of Bagan. They were built to withstand the region's fierce monsoons, with thick walls, dark passages, and an imposing, almost Brutalist aesthetic.
Getting to Mrauk U is an adventure, typically involving a flight to Sittwe followed by a multi-hour boat trip up the Kaladan River. The reward is a mystical landscape, especially at dawn when fog blankets the valleys, and the tops of the temples pierce through like islands in a sea of clouds.
Pro-Tip: The best time to visit is during the dry season (November to March). Hire an e-bike or a local guide with a jeep to explore the main sites and the surrounding Chin villages.
7. Vat Phou, Laos
Predating Angkor Wat by several centuries, Vat Phou is an ancient Khmer temple complex in southern Laos. It's dramatically situated on a hillside overlooking the Mekong River, with a long, stone-lined causeway leading up to a series of terraces and a central sanctuary where a natural spring once flowed.
While it's a UNESCO World Heritage Site, Vat Phou receives only a fraction of the visitors of its Cambodian cousins. The atmosphere is serene and contemplative. As you climb the worn stone steps, past gnarled frangipani trees, you can feel the immense history of the place. The views from the upper terrace are breathtaking, stretching across the vast plains below.
Pro-Tip: Vat Phou is easily accessible from the nearby town of Champasak. Rent a bicycle and cycle along the Mekong to the temple for a beautifully scenic journey.
8. Candi Sukuh, Indonesia
Perched high on the slopes of Mount Lawu in Central Java, Candi Sukuh is one of the most enigmatic and bizarre temples in all of Southeast Asia. Built in the 15th century, its main structure is a truncated pyramid that bears a striking resemblance to a Mayan temple. The site is famous for its explicit fertility carvings and unique iconography that deviates from standard Hindu-Javanese art.
The misty, high-altitude setting adds to the temple's profound sense of mystery. It feels less like a place of worship and more like the site of ancient, forgotten rituals. Standing before its strange obelisks and reliefs, you can’t help but wonder about the people who built it and the beliefs they held.
Pro-Tip: Combine a visit to Candi Sukuh with the nearby Candi Cetho. The best way to get there is by hiring a car and driver from Solo (Surakarta) or Yogyakarta.
9. Bagan's Hidden Temples, Myanmar
Everyone knows about Bagan's 2,000+ temples, but most visitors stick to a dozen of the largest ones. The real "Tomb Raider" experience is found by renting an e-bike and venturing down the dusty, unmarked dirt tracks. Here, you'll find hundreds of smaller stupas and temples that are completely deserted.
Many of these smaller structures are unlocked. You can push open a creaky wooden door and step inside to find original frescoes, silent Buddha statues, and narrow staircases leading to rooftop terraces with no one else in sight. It’s in these quiet moments, with an entire temple to yourself, that you truly connect with the magic of Bagan.
Pro-Tip: Get a good map (or use an offline map app), pack water, and just get lost. Some of the best discoveries are the ones you make by accident.
10. Prasat Phanom Rung, Thailand
Built atop an extinct volcano in northeastern Thailand, Prasat Phanom Rung is a breathtakingly well-restored Khmer temple. While not exactly "forgotten," its dramatic location and relative remoteness give it a powerful, epic feel. A long, grand causeway leads you to the main sanctuary, which is perfectly aligned to catch the rising and setting sun through its 15 doorways during specific times of the year.
The journey to the top of the volcano, culminating in the stunning view of the temple against the sky, is pure adventure. The intricate carvings depict scenes from the Ramayana, and the sense of order and cosmic alignment is palpable. It’s a masterpiece of Khmer architecture and astronomy.
Pro-Tip: Visit during the Phanom Rung Festival (usually in April) to see the solar alignment phenomenon, but be prepared for crowds. For a quieter experience, go on a regular weekday.
11. Sambor Prei Kuk, Cambodia
Before there was Angkor, there was Ishanapura, the capital of the Chenla Kingdom. Today, its ruins are known as Sambor Prei Kuk, a sprawling collection of over 100 pre-Angkorian brick temples scattered throughout a mature forest. These octagonal towers, decorated with unique "flying palace" carvings, represent a distinct and earlier style of Khmer art.
Wandering the shady forest paths from one temple cluster to another is a peaceful and enchanting experience. The site was recently declared a UNESCO World Heritage Site, but it remains wonderfully tranquil. You can see early examples of temple design that would later evolve into the grand stone monuments of Angkor.
Pro--Tip: Located near Kampong Thom, Sambor Prei Kuk makes for a perfect stopover on the drive between Phnom Penh and Siem Reap. Hire a local guide at the entrance to understand the history and symbolism.
12. Candi Cetho, Indonesia
Even higher up Mount Lawu than Candi Sukuh, Candi Cetho is its mystical, cloud-swept cousin. The journey to Cetho is spectacular, winding through lush tea plantations and misty mountain villages. The temple itself is a series of stone terraces leading up to a main platform, reminiscent of a Balinese temple but with a distinctly ancient Javanese soul.
The air is cool and often thick with fog, giving the entire site a dreamlike, ethereal quality. The stone turtles and phallic symbols hint at ancient fertility cults, and the atmosphere is deeply spiritual. It’s a place that feels suspended between the earth and the heavens.
Pro-Tip: Bring a jacket, as the weather on Mount Lawu can change in an instant. The tea plantations surrounding the temple are stunning and worth a walk through.
13. Wat Phu Asa, Laos
This one is truly off the beaten path. Located on the Bolaven Plateau in southern Laos, Wat Phu Asa is not a temple in the traditional sense. It's a mysterious site made of hundreds of flat rock pillars, stacked into crude tower-like structures. No one is certain who built them or why, with local legends attributing the work to ancient kings or even giants.
To reach the site, you'll need to trek through the forest, often with a local guide. The "temple" sits atop a rocky plateau, offering fantastic views of the surrounding jungle. It feels raw, ancient, and utterly wild—a genuine puzzle from a forgotten time.
Pro-Tip: The best way to visit is by arranging a tour or guide from Pakse. The trek is moderate, but the path can be tricky to find on your own.
14. Gedong Songo, Indonesia
The name "Gedong Songo" means "nine buildings" in Javanese. This remarkable site in Central Java features a series of small, 8th-century Hindu temples scattered across the slopes of Mount Ungaran. To explore them all, you have to hike along scenic mountain ridges, passing through vegetable farms and steaming volcanic fumaroles.
The adventure here is the journey between the temples. You can hike the whole route or, for a classic Javanese experience, hire a horse. The temples themselves are some of the oldest in Java, and their stunning placement against a backdrop of volcanic peaks makes for an unforgettable high-altitude adventure.
Pro-Tip: Go on a clear day for the best views of the surrounding volcanoes, including Merapi and Merbabu. The air is cool, so it's a pleasant escape from the heat of the lowlands.
15. Lembah Bujang, Malaysia
While Southeast Asia's temple scene is dominated by Khmer and Javanese ruins, Malaysia has its own ancient history hidden in the jungles of Kedah. The Bujang Valley was the site of a prosperous Hindu-Buddhist kingdom from as early as the 1st century AD. Today, archaeologists have uncovered over 50 ancient temple sites, known as candi.
The most significant and well-restored of these is Candi Bukit Batu Pahat, located in a serene forest setting. While not as monumental as their neighbours, these ruins are historically vital and offer a fascinating glimpse into the early trade and cultural links that connected the entire region. It’s a quiet, contemplative place for history buffs seeking a different kind of ruin.
Pro-Tip: The Bujang Valley Archaeological Museum is the best place to start. It provides context and has maps to help you locate the various scattered sites.
16. Prasat Mueang Sing, Thailand
Located on the banks of the Kwai Noi River in Kanchanaburi, Mueang Sing (Lion City) was a western outpost of the vast Khmer Empire. The main temple is built from laterite in the Bayon style of Jayavarman VII, and its four-faced gopuras will feel familiar to anyone who has visited Angkor Thom.
What makes it special is the setting. It’s surrounded by a massive, fortified wall and moat, and the entire historical park is a peaceful, well-maintained forest. You can explore the main prasat and its surrounding ruins with very few other people around, imagining what life was like for the soldiers and officials stationed at the far edge of the empire.
Pro-Tip: Mueang Sing is a great addition to a trip to Kanchanaburi to see the famous Bridge on the River Kwai. Rent a scooter for the day to explore the park and the beautiful countryside at your own pace.
Your Adventure Awaits
These sixteen temples are just the beginning. Southeast Asia’s jungles are still filled with secrets, and the spirit of discovery is alive and well for anyone willing to look for it. These places are more than just ancient stones; they are a direct link to a past that is both epic and mysterious. They remind us that even the greatest empires eventually return to the earth, and that there is profound beauty in that cycle.
So, the next time you plan a trip, look beyond the main attractions. Find the dotted lines on the map and follow them. You might just find your own forgotten temple, waiting silently in the jungle.
