Khao Kha Archaeological Site

Khao Kha Archaeological Site sits on a small standalone hill, about 72 metres high and roughly 850 metres long, in Sao Phao subdistrict, Sichon district — on the coast between Khanom and Nakhon Si Thammarat city. The ruins here are Brahmanical Hindu, not Buddhist: local heritage authorities identify Khao Kha as the most significant Shaiva (Shiva-worshipping, Pashupata sect) shrine complex found anywhere in Nakhon Si Thammarat province, dating to roughly the 6th-9th century CE.

Brick and laterite foundations run along the hill’s ridge, marking where shrine structures once stood — evidence of an ancient community that practised Shaiva Hindu ritual on this coast centuries before the region turned predominantly Buddhist. Fragments of religious sculpture and architectural pieces recovered here are now held by the Fine Arts Department, and information panels on-site explain what’s been excavated and dated.

Watch out: Don’t expect an intact temple. This is a ruins site — foundations, wall bases, and scattered stonework on an open hillside — not a standing structure, so manage expectations if you’re picturing something like Wat Phra Mahathat.

The appeal here is historical rather than visual: understanding that southern Thailand had an active Brahmanical Hindu tradition well before its current Buddhist identity took hold. Early morning is the practical time to go, before the coastal heat builds on the exposed hilltop.

Bring water, sun protection, and proper walking shoes for the low climb over uneven ground. There’s no public transport directly to the site, so a car or motorbike from Nakhon Si Thammarat city or Sichon town is the only realistic way in. If you’re staying on the Khanom coast, pair it with Hat Sichon or Tham Khao Wang Thong further along the same stretch, both a short drive from Sao Phao subdistrict.
