Khao Men, officially known as Khao Phra Sumeru, is a highly popular destination among adventure seekers who want to experience jungle trekking in southern Thailand. The trail is well known for its steep terrain. The most common starting point is Hill 499, with a hiking distance of approximately 3–4 kilometers and an average trekking time of 3–5 hours. Although the distance is not long, most of the route is steep and physically demanding.

One of the most appealing features of Khao Men is that it is free from leeches, allowing hikers to trek more comfortably compared to many other southern rainforests. Upon reaching the summit, visitors are rewarded with a unique highland forest where trees are relatively short and covered in thick green moss, ferns, and various orchid species, creating an atmosphere reminiscent of a fairytale forest.

The summit viewpoint offers a 360-degree panorama. On clear days, visitors can see nearby communities and the long stretch of the Nakhon Si Thammarat mountain range. The weather at the top is usually cool, windy, and often covered in mist, with temperatures significantly lower than the lowlands, especially toward the end of the year.

Most travelers choose a 2-day, 1-night trip, camping or setting up hammocks at the summit to enjoy sunset views, star-filled skies, and a breathtaking sea of mist in the early morning. Water sources near the summit are very limited, so hikers must prepare sufficient drinking and utility water, along with warm clothing and rain protection. Trekking Khao Men requires prior coordination with Yong Waterfall National Park officers to ensure safety and compliance with park regulations.

• By Private Car: From Nakhon Si Thammarat city, drive toward Na Bon District or Chang Klang District. From there, continue to Yong Waterfall National Park and the designated trekking starting point (it is strongly recommended to contact park officers in advance for guidance).

• By Public Transport: Take a minivan from Nakhon Si Thammarat city to Thung Song or Chandi, then get off at Na Bon District or Chang Klang District. From there, hire a motorcycle taxi or local pickup truck to reach the official trekking starting point arranged by the park authorities.

• The best time to visit is from January to July, when rainfall is lower. The park usually closes overnight stays from July to November for forest restoration.

• Prepare proper trekking shoes with good grip, rain gear, flashlight, and essential personal items.

• There are no facilities or restrooms at the summit, so tents or hammocks must be brought along (hammocks are recommended due to limited flat ground). Water sources are scarce, so bring enough water for the entire trip.
