Introduction

The Trishuli River is one of Nepal’s most popular and accessible rivers, known for its dramatic rapids, religious significance, and scenic beauty. Flowing from the Himalayas toward the plains, it plays a key role in Nepal’s hydrology, tourism, and culture. The Trishuli is not only a favorite for white-water rafting but also a lifeline for the regions it flows through.

Geographical Overview

• Origin: The Trishuli River originates from Gosaikunda Lake, a sacred glacial lake in the Langtang National Park.

• Length: Approximately 185 kilometers.

• Course: Flows southward through Rasuwa, Nuwakot, Dhading, and Chitwan, eventually joining the Narayani (Gandak) River.

• Tributaries: Includes the Langtang Khola, Bhotekoshi (from Tibet), and Trisuli Khola.

Cultural and Spiritual Significance

• The name “Trishuli” is derived from Lord Shiva’s trident (Trishul). According to legend, the river sprang forth when Shiva struck the ground with his trident.

• Gosaikunda, the river’s source, is a sacred pilgrimage site for Hindus and Buddhists, especially during the Janai Purnima festival.

• Numerous temples and ghats are situated along its banks, making the river an important part of local rituals and ceremonies.
