Ramkhamhaeng National Park

This national park lies southwest of Sukhothai Historical Park, and many ancient monuments have been discovered within its boundaries. It is dominated by a mountain called Khao Luang, picturesquely described by the National Parks Department as ‘like a giant ant hill in the middle of a rice field’, with four separate peaks rising to about 1,200 metres. Popular among Thais for its fresh mountain air, it receives few foreign visitors.

Besides climbing Khao Luang, most visitors like to see Sai Rung Waterfall, which drops around 100 metres over a cliff on the mountain, and several nature trails wind around the park headquarters. A few large wooden bungalows are available for rent, sleeping up to six people, and there is a restaurant on site.

• Visit early morning or late afternoon to avoid Thailand's midday heat and to maximise chances of seeing wildlife around the park's trails and viewpoints.
• Before setting out, check the park office for current trail conditions and any local restrictions-some attractions (waterfalls/viewpoints) require short hikes and may be closed after heavy rain.
• If you're aiming for quieter visits, choose weekdays or the shoulder seasons outside Thai public holidays when local day‑trippers are fewer.
