Main image

Kbal Spean is an archaeological and natural site in the Phnom Kulen area of Siem Reap province known for rock carvings in a riverbed, including numerous lingas and Hindu figures. The carvings are set along a sandstone streambed and on nearby outcrops.

Visitors follow a forest trail to reach the carved riverbed and a small waterfall; the main engraved section is reached after an uphill walk from the parking area. The site is valued for its concentration of riverbed sculptures and the combination of jungle, water and stone.

The reliefs and lingas on the riverbed date to the Angkor-period centuries, carved as ritual devices intended to sanctify the water flowing downstream to the temples. The site reflects religious practices and stone-working skills of that period.

Kbal Spean lies in the Kulen foothills north-east of Siem Reap, within a protected forested area that is accessed by a short drive from the main road followed by a marked walking trail.

  • Trail length: The trail from the car park to the main carvings is a moderate uphill walk of roughly 1.5 kilometres, so wear good footwear and carry water.
  • Seasonality: Best visited in the dry season when the carved riverbed is most visible; sections can be submerged or slippery during the wet season.

How to Get to Kbal Spean #

Kbal Spean is located in Phnom Kulen National Park northeast of Siem Reap. Drive from Siem Reap toward Banteay Srei and follow the park road to the Kbal Spean car park/visitor area (the drive is about an hour or so, roughly 40-60 km depending on route). From the car park there is a forest trail of around 1.5 km (about 30-45 minutes) to the river where the stone carvings are located.

Tips for Visiting Kbal Spean #

  • Start the trail to Kbal Spean as early as possible - it's a steep-ish 45-60 minute walk from the car park and much more comfortable before the midday heat.
  • Visit in the dry season if you want to clearly see the riverbed lingas and carvings; higher water levels in the wet season can hide many of the reliefs.
  • Allow extra time to continue upstream to the small waterfall pools beyond the carved stretch - many visitors turn back at the main viewing area and miss these quieter spots.

Best Time to Visit Kbal Spean #

Kbal Spean is best visited in the dry, cooler months (November-February) when the hike to the river carvings is drier and safer.
