The Khao Luang mountain is the highest summit of a massif of several hills with steep slopes. It is part of the Nakhon Si Thammarat Range, a subrange of the Tenasserim Hills.

Geologically this mountain formation consists of a granite core under loose soils. On steep slopes, the soil covering the mountains can cause landslides when saturated with water.

Some of the forests of the area were felled to give way to rubber plantations.[2]

Khao Luang National Park is named after Khao Luang mountain. The park is mountainous with many tall peaks along its range.

The park covers an area of 570 square kilometres (220 sq mi) with a large variety of wildlife and habitats, including mountains, forests, rivers and waterfalls. The park was designated a national park on 18 December 1974, becoming the ninth national park in Thailand. The headquarters of the park is 30 kilometres (19 mi) from the town of Nakhon Si Thammarat.

The mountainous park is a watershed for the Tapee River, Pakphanang River, Klai River and Pakpoon River, Nopphitam.


Due to the park's location on the peninsula, it receives monsoons from both the east and the west coasts and means that the park receives rain all year and also cold weather. There are two main seasons. Rainy season from May to January with the heaviest rainfall between October and December. Hot season is between February and April. Over the year the park receives approximately 3,500–4,500 millimetres (140–180 in) of rainfall. The highest temperatures range from 28 °C (82 °F) to 30 °C (86 °F) and the lowest from 15 °C (59 °F) to 15 °C (59 °F)in January and February.[citation needed]
