Things to do in Uttaradit.

The province's defining figure and the first thing to understand about it. Phraya Phichai was the ruler of Mueang Phichai who fought off the Burmese after the fall of Ayutthaya in 1767, earning the title Dap Hak — "broken sword" — for shattering one of his weapons in hand-to-hand combat. His monument stands before City Hall and appears on everything from the provincial motto to local branding. Free, central and a five-minute stop, but it explains the place.

The temple whose mondop appears on the provincial seal. It is built over a laterite block that tradition holds was used by the Buddha in his search for enlightenment, and the seal — first designed in 1940, later gaining a garuda and the province's name — shows exactly that structure. Nearby at Mon Cham Sin sits the Phra Luea Buddha image, cast from the gold left over after Phitsanulok's celebrated Phra Phuttha Chinnarat was completed, and placed there on the instruction of King Chulalongkorn during a royal visit.

Laplae (ลับแล) means "hidden from sight", and its legend is one of the best known in Thailand: a village reachable only by the truthful, where a visitor who lies to a crying child is sent away — with a bag of turmeric roots that turn to gold. The district is also northern Thailand's biggest durian producer, roughly 27,000 rai under orchard, and the source of the Longlaplae and Linlaplae varieties, famous for lacking durian's usual smell. The durian festival runs around the start of June. Handwoven naturally-dyed Laplae cotton is a five-star OTOP product and worth seeking out.

Teak is the provincial tree and the motto's fourth boast, and the largest known teak tree in the world stands in this 35 km² park of mixed deciduous forest. Estimated at more than 1,500 years old and discovered in 1927, it stands around 37 metres tall with a base circumference near ten metres — it was once far taller, before a storm broke off the upper trunk. Getting there is a real drive on winding roads, and it is the province's signature natural sight.

The dam impounds the Nan River into an artificial lake of roughly 250 km² beneath the surrounding ranges — the province's big open landscape, and the centre of local boating, fishing and weekend trips. The drive up from the town takes you out of the rice plain and into the forested uplands that make up most of Uttaradit's 55.9% forest cover.

Langsat (ลางสาด) is the fruit named in the provincial motto, and its thick-skinned relative longkong is grown alongside it; both taste broadly like longan. The langsat festival runs each year around the middle to end of September and is the province's main annual event after the June durian festival. If you visit Uttaradit once, timing it to one of the two fruit seasons is the way to do it.

Forest covers 4,415 km² of Uttaradit — 55.9% of the province — and three national parks and four wildlife sanctuaries sit within it, mostly in the upland districts running toward the Lao border. This is the quiet, unpackaged end of Thai nature tourism: few facilities, few visitors, and no infrastructure built for foreigners. Go with a vehicle, a full tank and realistic expectations.
