Phnom Kulen, or Kulen Mountain, is a sacred mountain and a national park located about 50 km from Siem Reap. Known as the birthplace of the ancient Khmer Empire, it offers a blend of natural beauty, historical significance, and spiritual sites

Hundreds of phallic symbols (lingas) dedicated to the Hindu god Shiva are carved into the riverbed, located on the way to the top of the mountain.The site is considered a holy spiritual place where pilgrims seek blessings.It is accessible via a moderate hike through the jungle.

This pagoda is home to the country's largest reclining Buddha, an 8-meter statue carved into a giant sandstone boulder.

There are two main waterfalls at Phnom Kulen. The lower, more accessible waterfall is wider, dropping 4 to 5 meters.The upper waterfall is taller, dropping 15 to 20 meters, and is more secluded.Both waterfalls have natural pools for swimming and are popular picnic spots.

The "1000 Linga" on Kulen Mountain refers to the carvings in the Kbal Spean archaeological site, which include over a thousand linga (phallic symbols of the Hindu god Shiva) and other mythological figures carved into the riverbed and banks of the Siem Reap River. These carvings date back to the 11th and 12th centuries and are considered sacred, believed to purify the water and make it fertile.
