They are Buddhists and large minority of Hindus. Centuries of cultural influence from Tibet and its northern neighbours – which adopted the Tibetan culture to a heavy extent resulted in many Gurungs gradually embracing Tibetan Buddhism–particularly among Gurungs in the Manang region – over the centuries, particularly the Nyingma school.
 Priestly practitioners of Gurung Dharma include lamas, ghyabri (klehpri), and pachyu (paju). Shamanistic elements among the Gurungs remain strong and most Gurungs often embrace Buddhist and Bön rituals in all communal activities.
Gurung music is one of the traditional form of music from the indigenous Gurung community of Nepal. Gurung society is very rich in its cultural heritage and music plays an important role in their everyday life. Whather it is a child's birth, a marriage ceremony or a funeral, music plays a vital role in the process.
Some of the Gurung people are renowned for their use of mad honey, which they collect from the Himalayan honey bee, both for its medicinal and hallucinogen properties.
