Hot water spring located in Bahundanda Fedi of Lamjung district is popular among the tourist trekking in Annapurna circuit.
It seems, there are a lot of small hot springs along Marsyangdi river that first runs north between the Annapurna and Manaslu. Falling along the Main Central Thrust, in the Marsyandi Valley, central Nepal, "waters are heated by the elevated geothermal gradient, and mix with deep-sourced carbon dioxide before degassing at the surface"
This blogger concludes, along the Marsyangdi river, there are anywhere between three and seven hot springs.
I like u bhaundada.
