Khao Kho International Library

Khao Kho International Library is a public visitor attraction in Phetchabun’s Khao Kho district — a distinctive diamond-shaped building with reflective glass, built in 1995, that draws people as much for the architecture and mountain views as for the book collection inside. Entry costs 20 THB for foreign adults, 10 THB for Thai adults, and it’s open daily, roughly 08:00-17:00.

The building itself is the draw. Its angular, glass-heavy design stands out against the rest of Khao Kho’s hilltop attractions, and the interior takes advantage of that with reading areas positioned to look out over the surrounding mountains. The shelves hold a mix of Thai and international titles, spanning several languages, but this isn’t a research library in the conventional sense — it functions as a public cultural stop, and most visitors spend their time on the building and the view rather than working through the stacks.

Khao Kho sits at altitude, so the air here runs noticeably cooler than lowland Phetchabun — a genuine part of the appeal for Thai visitors escaping the heat, and worth knowing if you’re travelling light. The library is one stop among several hilltop attractions clustered in the district, which is why most people fold it into a half-day loop rather than visiting on its own.

Insider Tip: Combine the library with nearby Khao Kho stops in one loop — it’s a short visit on its own (most people spend 20-30 minutes), so pairing it with the Wat Phra That Pha Son Kaew mosaic temple or Khao Kho National Park makes better use of the drive up.

There’s no public transport route directly to the library — reaching it means driving, renting a motorbike in Khao Kho town, or joining a Phetchabun day tour that covers the district’s main sights. Bring a light layer even outside the cool season; the elevation keeps temperatures down year-round compared with Phetchabun’s lowland towns.
