Prang Sam Yot (Monkey Temple),Thailand

Prang Sam Yot is a Khmer-style temple complex in Lopburi, central Thailand, dating from the late 12th to early 13th century. Originally built in the Angkor/Khmer architectural tradition and dedicated to Hindu deities, the site later took on Buddhist significance. It is a key example of Siamese–Khmer cultural layers and an important archaeological and religious landmark in Lopburi province.

Places to visit

  • Three central prangs (Khmer towers) forming the temple’s distinctive profile
  • Populations of long-tailed macaques frequenting the ruins
  • Nearby historical sites in Lopburi such as King Narai’s Palace and Wat Phra Si Rattana Mahathat

Unique Aspects

  • Distinctive Khmer prang architecture (sandstone/baked brick elements)
  • Photogenic interactions between monkeys and the ancient ruins — especially at sunrise and sunset
  • Bas-reliefs and traces of Hindu and Buddhist iconography showing cultural layering

Things to do

  • Observe and photograph the monkeys in their naturalized urban environment
  • Explore and climb (where permitted) the ancient prangs and take skyline photos at sunrise/sunset
  • Combine a walking tour of Lopburi’s historic center — visit King Narai’s Palace and local markets
  • Attend the Monkey Buffet Festival (annual event in November) if visiting at that time

Best Time to Visit

November–February for cooler, more comfortable weather; late November for the Monkey Buffet Festival. Avoid the hottest months (March–May) if possible.

Weather Conditions

Tropical; hot season March–May, rainy season June–October, cooler season November–February. Expect high humidity outside the cooler months.

Entry Fees & Permits

Access to the exterior and grounds is generally open daily from early morning to early evening (times vary locally). Some areas may charge a small entrance fee or donation; fees and opening hours can change so check locally on arrival.

Accessibility

Lopburi is accessible by road and rail from Bangkok (approx. 2–3 hours by train or 2–3 hours by car). The nearest major airports are Don Mueang (DMK) and Suvarnabhumi (BKK) in Bangkok, followed by a train or bus/car transfer. The temple is within Lopburi town and a short walk or tuk-tuk ride from Lopburi station.

Recommended Duration

1–2 hours at Prang Sam Yot to explore the ruins and observe the monkeys; allow a full half-day if combining with nearby sites.

Clothing & Gear Tips

Lightweight, breathable clothing for the tropical climate; dress modestly (covered shoulders/knees) when entering nearby active temple areas. Bring sturdy closed shoes, sun protection (hat, sunscreen), water, and a small first-aid kit. Secure bags and valuables — monkeys are attracted to food and shiny objects.

Local Food & Souvenirs

Try local central-Thai street food in Lopburi’s markets (grilled meats, noodle dishes, sweets). Popular local souvenirs include banana chips, local snacks, and handcrafted items sold near markets.
