Geographically located in the Lower North on the bank of the Ping River, Kamphaeng Phet is 358 kilometres from Bangkok. To its East are riverine flatlands while the western areas are made up of high mountains lush with fertile forests where a number of national parks have been established.

Areas along the river bank at present-day Mueang district used to host several ancient towns which had played a major role as strategic front-line frontiers since Sukhothai was the kingdom's capital down through the times of Ayutthaya and early Rattanakosin (Bangkok) eras. In fact, the name Kamphaeng Phet actually means as strong as walls or forts make of diamonds.

Kamphaeng Phet covers an area of 8,607 square kilometres. It is divided administratively into 9 districts, namely, Mueang Kampheang Phet, Phran Kratai, Khlong Khlung, Khanu Woralaksauri, Sai Ngam, Lan Krabue, Khlong Lan, Sai Thong Watthana and Pang Sila Thong and 2 sub-districts, Bueng Samakkhi and Kosamphi Nakhon.

The Nop Phra Len Phleng Fair is held during the celebrations of Makha Bucha (around February). A tradition since the times of Sukhothai, it is described in the inscription stone found at Nakhon Chum of how processions were organised to pay homage to the town's major religious sites. The fair today consists of colorfully decorated parades of participants dressed in ancient attires crossing the Ping to pay homage to the Holy Relic on the Nakhon Chum side of the river.

The Kluai Khai Fair is held in September each year to promote the local banana for which the province is famous. There are banana contests and competitions on the making of Krayasat (a local sweet), as well as many entertainment performances.
