Beauties of Khao Sok National Park

Chiew Lan Lake (Ratchaprapha)

There is a magnificent lake positioned approximately 65 kilometers east of The National Park of Khao Sok Offices. The drive there would take about one hour. It was developed in 1982. Limestone outcrops reaching higher than 950m stand above the lake. 

Chiew Lan Lake is normally visited as part of a day tour or an overnight tour. Others like to travel alone. Tours usually transport visitors to the location and provide guides. Aside from canoeing, if you fancy visiting the rainforest while you’re there, there are trekking possibilities across the lake. You can rent a boat for 2000 Bahts (about 65USD) per day from local fishers at the river’s entry. In addition, you can discover the coves, waterways, and caves along the lakefront by renting a boat.

From the southwestern coast, you can walk to two caves. The limestone formations of Tham Nam Thalu and the underground streams are grand. The rainy season is not a recommended period for visiting because there have been incidents in the past. 

The other one is Tham Si Ru. Between 1975 and 1982, communist rebels used Tham Si Ru’s four interlinked passageways as a hidey-hole. There is a pathway along Chiew Lan Lake’s southwestern shore that leads to the cave.

Ton Kloi Waterfall 

The key path of the national park, which passes across the Sok River and heads to Ton Kloi Waterfall, is 7 kilometers long. Ton Kloi is a gorgeous waterfall that originates from the canal Klong Sok. It’s a year-round, singular waterfall that flows down from a high cliff.

The path is mostly walkable by yourself. However, the last 4 kilometers of this path, over the path head, will necessitate the help of a guide. It’s a genuine jungle path that takes you through many tinier waterfalls, a place for you to swim, and a gorge before ending at Ton Kloi Waterfall.

There are other waterfalls in this park, and all of them are less than 7 kilometers away from the office of Khao Sok. However, remember that some of them are not attractive through the dry season. 

Khlong Long

The most common waterway around the lake is Khlong Long, which is positioned on the northeast side of the lake, is less than 20 kilometers from Cheow Lan Lake Dock. Limestone slopes, a cave, and a relaxing perspective are the most satisfying parts of this waterway, and travelers can reach them after a two-and-a-half-hour hike through the woods. One can see five raft houses in Khlong long. They are in acceptable condition.

Khlong Saeng

This waterway is about 25 km from Ratchaprapha Dam. It was once considered the most distant river in Thailand before the time that the dam was constructed. The Klong Saeng River fills the lake too. You have to get the permits from the Khao Sok office and expend some money to enter the area.

This secluded section of the lake is perfect for hiking and nature observation. Hiking through a nature reserve, it is possible to view waterfalls, mines, and mammals such as gibbons and deer. Occasionally, even more, interesting animals like elephants, mainland serow, great Argus, and others would be noticeable. The preserve is also home to distinctive types of bears.

Khlong Mon

On the northern side of the lake, Khlong Mon is about 25 kilometers from Cheow Lan Lake Dock. The region is characterized by high heels and shallow valleys that make it an excellent site to see hornbills, eagles, and other species. An entertaining path through the woods will lead west to the Khlong Saeng waterway, taking less than 5kilometers. On the north side of the waterway are other smaller trails that you can access. Tam Gia is the single raft house of this area.

Things to Do in Khao Sok National Park

River Tubing 

It’s possible to rent Inner Tubes and float the river throughout the stormy season as the river is full. A few organizations in the area provide transport to and from the starting point. This water activity must take about an hour to 1.5 hours. Note that you have to pay about 400 or 500 Bahts (13-15 USD) per person. 

Canoe Trip

Consider that canoeing provides a more enjoyable option than tubing when you don’t like floating in the water. Canoeing down the gently flowing Sok River is the perfect carefree activity. It’s even better if you have a canoe guy to take care of all the difficult work. Moreover, they are experts in finding animals along the river as well.

You may be fortunate enough to recognize distinctive species. Apart from the wildlife, there are beautiful limestone cliffs covered in dense jungle, as well as some regional communities along the river. Locals fish, wash laundry, and get their water for everyday use from the river. An excursion to a cave might also be fun later. This must take about two hours and a half, costing about 800 Bahts (about 25 USD). 

Bamboo Rafting

This guided journey on a moving bamboo raft takes you off the tourist trail. With the help of a leader, you will identify distinctive animals and plants as you float down the river. The excursion includes exploring a cave and trekking across the area. Just like the Canoe trip, Bamboo rafting might take a little longer than the other mentioned water activities (about 4 hours) and costs 1200 Bahts (about 38 USD)

Wildlife Watching

The whole park is full of distinctive species, some infrequent and others easily observable. With some luck, you might be able to see mammals like long-tail macaques and banded-langurs. However, bigger mammals like elephants are not likely to appear near the common tourist treks. Amphibians, snakes, and lizards are usually observable in ways that end up in the waterfalls. A fine time to see reptiles and amphibians is in the dusk.
