Khao Sok National Park: A vast natural wonderland

In terms of sheer beauty, few places in the world can compare with Khao Sok National Park in Thailand. This rainforest, located between Phuket and Samui, is over 160 million years old and is an incredibly diverse ecosystem, home to an estimated 5% of all species on Earth.

A tour through this park is therefore definitely a highlight of any trip to Southern Thailand.

The majority of Khao Sok’s history is geological in nature. Soil erosion and changes in sea level shaped the lush green landscape that you can visit today over millions of years. The limestone that runs throughout the park was formed by the collision of tectonic plates—the same process that created the Himalayas. Over countless years, the limestone was eroded by rainwater dripping through the rainforest canopy, resulting in the impressive rock formations we see today.

In the 1960s, the region experienced extensive mining and logging. As a result, hunters, loggers, and miners were banned from the park and the land was protected. The government also eventually recognised the region’s incredible biodiversity as a treasure and declared Khao Sok a national park in 1980.

Today’s national park covers 739 km² and is full of plants, animals, and many scarcely explored corners.

The rainforest of Khao Sok is older than the Amazon and has flourished thanks to the constant rainfall and the steady climate in this part of Thailand. The climate is humid all year round, with average temperatures between 24 and 31°C. Especially during the rainy season from May to November, regular showers provide refreshment.

The sheer size of the national park can be overwhelming, so it is recommended to join a tour. This way, you can explore the park safely and will not miss any of its highlights. Guides can show you the way and lead you to points of interest, and they are also required on most trails through the park.

The jewel of Khao Sok is Cheow Larn Lake, a 165 km² reservoir surrounded by limestone mountains. The lake is not only stunning, but also offers plenty of activities for visitors, including floating bungalows where you can stay overnight or enjoy a meal. If you stay in one of the floating huts, you can jump straight into the lake from your bungalow!

The main means of transport on the lake are longtail boats, which allow you to take exciting trips along the channels leading into the jungle. Kayaking, paddleboarding and fishing are popular activities. However, you can also simply admire the emerald-green water and the contrast with the lush rainforest all around.

The biodiversity of Khao Sok is incredible. Here, 200 plant species grow per hectare, including a thousand species of orchids and the Rafflesia, the largest flower in the world with blooms up to 90 cm across. Figs and bananas provide abundant food for the local wildlife, and bamboo and palms also grow here in abundance.

Speaking of wildlife: Over 300 bird species, 48 mammal species, and countless insects and reptiles find a safe haven in this ecologically valuable rainforest. Several rare bird species have also been recorded in the national park. Our favourites are the hornbills, with a wingspan of 1.5 metres!

Malayan bears, Asiatic black bears, tapirs, marbled cats and wild boars are just some of the animals that inhabit the extensive park. Even the critically endangered tigers are said to still exist here, although none have been sighted for decades.

Khao Sok is also home to around 200 wild Asian elephants. They roam freely through the rainforest, but are not easy to spot. Some of our holidays include ethical encounters with elephants, where the animals move freely in an area without chains and riding them is strictly prohibited.

The small village by the river, located right on the doorstep of the national park, is also a good base for exploring Khao Sok. There are numerous guesthouses, shops and restaurants, and you can sign up for a night safari or a visit to the nearby elephant sanctuary. Tubing, canoeing and swimming in the river are also possible.

Caves, waterfalls, jungle hikes and encounters with wild animals – the possibilities in Khao Sok National Park are virtually endless. Pack your binoculars and make the most of your time in one of the oldest ecosystems on Earth. Especially during a stay at Cheow Lan Lake, you can fully immerse yourself in a prehistoric world.
