Hiking up to the World Peace Pagoda, also known as the Shanti Stupa, involves a relatively short hike (about 1.5 hours going uphill) but it rewards you with uninterrupted views of Fewa Lake and Himalayan mountain ranges.
To begin the hike, you will need to hire a boat driver to row you across the lake, but this adds to the fun of the adventure.
At the top of the hill where the Peace Pagoda is situated, there are a few restaurants and coffee shops where you can stop for a meal or drink before hiking back down. All in all, it can be done in half a day or less.
