Hidden deep within Khao Sok National Park, Coral Cave — locally known as Pakarang Cave — is one of the most fascinating natural attractions near Chiew Lan Lake. Surrounded by ancient rainforest and accessible by longtail boat across Cheow Lan Lake, this limestone cave reveals an underground world shaped over thousands of years by mineral-rich water and time.
Inside Coral Cave Khao Sok, dramatic stalactites and stalagmites rise from the cave floor and ceiling, forming intricate natural sculptures that resemble coral formations — giving the cave its name. Soft light filters through the cave entrance, reflecting on shallow pools of water and illuminating the golden limestone walls. The atmosphere is cool, mysterious, and unforgettable, making it a highlight of many guided tours in Khao Sok National Park.
A typical Cheow Lan Lake cave tour begins with a scenic boat ride across emerald waters, followed by a short jungle walk before entering the cave with an experienced local guide. Visitors navigate through narrow passages and open chambers, discovering unique rock formations that have developed over centuries. The cave’s natural beauty adds depth and adventure to any Khao Sok 2 days 1 night or extended rainforest itinerary.
Exploring Coral Cave in Khao Sok offers a different perspective of the park beyond the lake’s limestone cliffs and floating bungalows. It showcases the geological history of Chiew Lan Lake, formed after the construction of Ratchaprapha Dam, where submerged valleys and karst mountains create both stunning surface scenery and hidden underground systems.
For travelers seeking a more immersive Khao Sok private tour, adding Pakarang Cave to the itinerary enhances the experience with a blend of adventure, education, and natural wonder. Within the vast landscape of Khao Sok National Park, Coral Cave stands as a testament to the park’s diverse ecosystems — from rainforest canopy to freshwater lake, and deep into the limestone heart of southern Thailand.
