Qilai Main Peak, Mountain peak in Taroko National Park, Taiwan.

Qilai Main Peak rises to 3,560 metres in the Central Mountain Range, on the border of Hualien County's Xiulin Township and Nantou County's Ren'ai Township. A numbered third-class triangulation stone sits at the summit. The main peak is lower than the 3,607-metre Qilai North Peak to its north, which carries a first-class marker.

The mountain has long served as part of traditional travel routes used by indigenous communities, who established knowledge of the terrain over many generations. Later surveying and exploration by colonial and modern authorities led to the development of organized trails and the integration of the summit into a managed national park system.

The name Qilai derives from the Sakizaya people (Sakizaya: Sakizaya, Sakidaya); "Qilai" originally referred to Hualien, and Qing-era maps marked the western ridges as "Qilai Mountain", later written by Han settlers as "Aoqilai" or "Qilai". The plain where this people lived, the Manlun Creek plain, was called "Qilai Plain".

The trail requires multi-day backpacking with overnight stays at mountain lodges or campsites, so good physical preparation is essential beforehand. Weather conditions change rapidly at higher elevations, so bring warm layers and rain protection regardless of the forecast.

The name Qilai comes from the Sakizaya people: Qing-era maps marked the mountains west of Hualien as Qilai, and the plain where the Sakizaya lived became known as Qilai Plain. The range's highest point is not the main peak but the 3,607 m northern peak.
