Getting There & Around

How to Get to Khao Luang

Khao Luang (in Khao Luang National Park) is in Nakhon Si Thammarat province. The usual access point is from Nakhon Si Thammarat town (the provincial capital); from there drive inland on the provincial roads toward the national park. The park headquarters and trailheads are reached by car or local minibus/songthaew services from town - the drive into the park is typically on provincial roads and takes on the order of tens of kilometres.

Once at the park entrance you proceed on foot along marked trails to reach viewpoints and the forested slopes of Khao Luang.

Tips for Visiting Khao Luang

  • Set out early in the morning for clearer summit views and cooler hiking conditions; the usual trailheads start from the Khao Luang National Park headquarters near Nakhon Si Thammarat town.
  • Combine a summit attempt with visits to the park's lower trails and waterfalls - the shaded lower tracks are often quieter and show a different side of the park that many summit-focused visitors miss.
  • Avoid the monsoon months (heavy rains and slippery trails); aim for the dry season (roughly November-February) for the most reliable trail conditions and viewpoints.
