More than a stop between Nakhon Sawan and Sukhothai — a UNESCO historical park, superb forest temples, the old Diamond-Wall ramparts, Nakhon Chum's old town and a national-park waterfall on the doorstep.
Kamphaeng Phet is one of Thailand's most under-visited heritage provinces — which is part of its appeal. Its UNESCO historical park and Aranyik forest temples reward a proper look, the old Diamond-Wall ramparts tell the story of a Sukhothai frontier fortress, and the forested west adds a national-park waterfall to the mix.
The heart of the province: the laterite ruins inside the old city walls, including Wat Phra Kaeo and Wat Phra That, part of the UNESCO World Heritage Historic Town of Sukhothai and Associated Historic Towns. Compact, atmospheric and far less crowded than Sukhothai's park — the single must-see.
Just north of the walls, the Aranyik ('forest monastery') zone holds some of the finest monastic ruins in Thailand — Wat Phra Si Iriyabot, with its four great Buddha images in different postures, and Wat Chang Rop, whose chedi is buttressed by rows of stucco elephants. Shaded and quiet, it's the most rewarding part of the park.
The province takes its name — 'Diamond Wall' — from the formidable earthen-and-laterite ramparts that ringed the old city. Substantial stretches survive, along with the moat, giving a real sense of the frontier fortress this once was on the Sukhothai kingdom's southern edge.
On the west bank, Nakhon Chum is the province's older settlement, with its own temples, a traditional riverside market and a quieter, lived-in feel. It's an easy add-on to the historical park and a good window on everyday Kamphaeng Phet life.
In the forested western mountains, Khlong Lan National Park protects the tall, single-drop Khlong Lan Waterfall and cooler highland scenery — a genuine day trip from the city, alongside the neighbouring Khlong Wang Chao and Mae Wong national parks.
Kamphaeng Phet is famous nationwide for its kluai khai (small, sweet 'egg bananas'), celebrated each year at the Sart Thai / Kluai Khai banana festival. Roadside stalls and markets across the province sell them fresh and in every sweet variation — a small, tasty piece of local identity.
Above all, the Kamphaeng Phet Historical Park — a UNESCO World Heritage site of laterite temple ruins, including the atmospheric Aranyik forest-temple zone — and the old 'Diamond Wall' ramparts the province is named for. It's also famous nationwide for its kluai khai (egg bananas) and for the Khlong Lan National Park and waterfall in its forested west.
Yes — it's often skipped between Nakhon Sawan and Sukhothai, but the historical park is one of Thailand's most rewarding and least-crowded ancient sites, and the Aranyik temples in particular are superb. Add Nakhon Chum's old town and a day trip to Khlong Lan, and it easily justifies an overnight stay.
Khlong Lan National Park and its waterfall are the obvious one, within the province's forested west. Sukhothai's UNESCO historical parks are about an hour and a half north, and Nakhon Sawan and its Bueng Boraphet lake are roughly two hours south — both easy on Highway 1.
Kluai khai — the small, sweet egg banana the province is known for across Thailand, celebrated at its annual banana festival. You'll find it fresh at every market and roadside stall, and dried, fried and candied too.
