Key Takeaways
- This is not a guide to the main temples (Wat Mahathat, Wat Phra Si Sanphet). You can find those everywhere. This is for when you have already seen the classics and want something weirder.
- Some of these “hidden gems” are not that hidden. Wat Tha Ka Rong is famous on Thai social media. Expect other visitors.
- Others are genuinely obscure. The Portuguese church ruins are easy to miss. The underground tunnels may require asking a local monk.
- Do not expect perfect signage or English explanations. Bring a map app and a sense of adventure.
- Not all of these places are “beautiful” in the traditional sense. Some are eerie, kitschy, or just strange. That is the point.
Quick Facts: Before You Go Off the Beaten Path
| Category | Detail |
|---|---|
| Best For | Repeat visitors to Ayutthaya, photographers, explorers, people who like weird temples |
| Not For | First-time visitors who haven’t seen Wat Mahathat yet |
| Transport | You will need a motorbike, a tuk-tuk hired for the day, or a very robust bicycle. These sites are spread out. |
| Signage | Poor to non-existent. Use Google Maps or a GPS app. |
| Food | Limited. Bring snacks and water. |
| Crowds | Low (except Wat Tha Ka Rong on weekends). |
| Entry Fees | Most are free or very cheap (20-50 THB donation). |
This is not a list of “secret” temples that are actually just less-visited corners of the main historical park. It is not a guide to unsafe or off-limits areas. And it is not a recommendation to skip the main ruins. See those first. Then come here.
The Hidden Gems (From Least to Most Weird)
1. Wat Yai Chai Mongkhon (Is This a Hidden Gem? No, But It’s Often Rushed)

Why go: People rush through it to get to the main park. It deserves a proper visit. The massive chedi, the row of meditation Buddhas, and the reclining Buddha are excellent.
Is it secret? No. It is a major temple.
Why is it on this list? Because most tourists spend 20 minutes here. You should spend an hour. Climb the chedi. Walk the row of Buddhas slowly. It is not hidden, but it is under-appreciated.

2. Wat Choeng Tha (The Whispering Buddha)

What it is: A small, active temple off the main tourist trail. It has an ancient Buddha statue that, due to the unique acoustics of the building, seems to “whisper” when you stand in a specific spot.
Why go: It is a genuine acoustic phenomenon. It is also a quiet, peaceful place with no crowds.
How to find it: It is located southeast of the main island, near the confluence of the rivers. Look for it on Google Maps. It is a short detour from Wat Yai Chai Mongkhon.
Warning: Do not expect a dramatic effect. It is subtle. Speak softly and listen.
3. Wat Phra Ngam (The “Temple of Nightmares”)

What it is: A ruined temple that has been almost completely consumed by a strangler fig tree. The roots cover the main Buddha image. It is dark, eerie, and very photogenic.
Why go: It is the ultimate “temple in a tree” experience, even more dramatic than Wat Mahathat’s famous head.
How to find it: It is north of the main island, past the bypass road. It is not in the central park. You will need a motorbike or a tuk-tuk.
Is it haunted? Locals say yes. At night, it is certainly spooky. Go in the late afternoon for the best light.
4. Wat Maheyong (The Underground Tunnels)

What it is: A less-visited temple ruin with a feature most tourists miss: a series of underground tunnels and meditation cells.
Why go: You can actually go down into the tunnels (with permission). It is a cool, dark, and unique experience compared to the open-air ruins.
How to find it: It is on the east side of the main island. Look for the signs. Ask a monk or a local guide to show you the tunnel entrance.
Warning: The tunnels are narrow and dark. Bring a flashlight. Do not go alone.
5. San Pedro Church Ruins (The Forgotten Portuguese Settlement)

What it is: The ruins of a 17th-century Dominican church, part of the old Portuguese settlement in Ayutthaya.
Why go: It is one of the only non-Buddhist ruins in the park. It is a fascinating reminder of Ayutthaya’s cosmopolitan past. The crumbling brick walls feel like a forgotten European ruin dropped into Thailand.
How to find it: It is located in the Portuguese settlement area, south of the main island, across the river. It is signposted, but the road is small.
Best time: Late afternoon, when the light hits the red brick.
6. Wat Tha Ka Rong (The Carnival Temple)

What it is: An active temple that has been renovated with neon lights, animatronic figures, and coin-operated donation machines. It is a surreal, kitschy spectacle.
Why go: It is the polar opposite of the somber, ruined temples. It is fun, weird, and genuinely unique to Thailand.
Is it a “hidden gem”? It is famous among Thai tourists, especially on weekends. But most foreign visitors miss it.
How to get there: West bank of the river, 3 km west of the main island. The weekend floating market is a bonus.

How to See These Hidden Gems
| Method | Best For | Notes |
|---|---|---|
| Motorbike rental | Independence and speed | The best way to cover the far-flung sites. Wear a helmet. |
| Tuk-tuk hire for the day | Groups of 2-3, no motorbike experience | Negotiate a flat rate (800-1200 THB for 6-8 hours). Give the driver the list of names. |
| Bicycle | Only if you are very fit | Distances are long (10-15 km from the central zone). Not recommended in the hot season. |
Do not try to walk to these. You will be exhausted and dehydrated.
The Truth About “Hidden Gems”
Most of these places are not “secret.” The monks know about them. The locals know about them. Thai tour groups sometimes visit Wat Tha Ka Rong. A “hidden gem” just means a place that is not on the first page of a Google search for “Ayutthaya temples.”
That does not make them bad. It makes them less crowded. Go with curiosity, not with an expectation of being Indiana Jones.
Summary
Ayutthaya has many lesser-known sites beyond the main historical park. These include Wat Choeng Tha (the Whispering Buddha), Wat Phra Ngam (the “Temple of Nightmares”), Wat Maheyong (with underground tunnels), the San Pedro Church ruins (Portuguese settlement), and Wat Tha Ka Rong (the “Carnival Temple”). Most are free or have a small entry fee. They are best accessed by motorbike or a hired tuk-tuk. The main temple guide is the Ayutthaya Historical Park.
You have seen Wat Mahathat and Wat Chaiwatthanaram. Now get weird.
- Explore the kitsch of Wat Tha Ka Rong.
- Walk the eerie grounds of Wat Phra Ngam.
- Then reward yourself with a cold drink at the hidden lotus pond cafe (Baan Thai Rong).
