Wat Thettharamnawa (Wat Tha Sai)

4.7(1,248 reviews)

Tucked away in the village of Ban Tha Daeng within Tambon Na Toei, Wat Thettharamnawa — commonly known as Wat Tha Sai — is a traditional Buddhist temple serving the local communities of Phang-nga province. Situated a short distance from the better-known tourist corridors of Khao Lak, it offers travellers a quieter, more genuine encounter with Thai religious culture away from the crowds. Visitors can expect a serene and unhurried atmosphere typical of a working community temple. The grounds reflect the devotional life of the surrounding villages, with shrine structures, Buddhist statues, and the kind of lived-in character that distinguishes a place of genuine worship from a tourist-facing site. Its consistently strong visitor ratings suggest that those who make the effort to seek it out find the experience quietly rewarding. As with all Buddhist temples in Thailand, visitors should dress respectfully — shoulders and knees covered are standard — and remove footwear before entering any buildings or shrine areas. There are no published opening hours, so visiting during daylight hours on a weekday morning tends to align best with temple activity. The temple has no website, so it is worth asking locally or checking with accommodation in the Khao Lak area for directions, as the address falls within a rural district where signage may be limited.

Tips for Visiting Temples & Culture

Dress Modestly

Cover shoulders and knees at all temples. Carry a light scarf or sarong — some temples lend wraps, but not all. Shoes come off before entering any building with a Buddha image.

Mind Your Feet

Never point your feet at a Buddha image or a monk — it's considered deeply disrespectful. When sitting inside a temple, tuck your feet behind you or to the side.

Ask Before Photographing

Exterior photos are almost always fine, but some interior halls prohibit photography. Look for signs, and never pose irreverently with Buddha images — it's a legal offense in Thailand.
