Pokhara's natural environment is its most vital asset, defined by lakes, rivers, and the towering Annapurna massif.
* **Air Quality**: Generally cleaner than Kathmandu, though PM2.5 levels can spike during the dry season (March-May) due to forest fires and dust. The monsoon (June-September) clears the air significantly. * **Water Bodies**: The city is famous for its lakes—Phewa, Begnas, and Rupa. Phewa Lake faces ongoing challenges with siltation from the surrounding hills and agricultural runoff. Conservation efforts are ongoing to prevent the lake from shrinking. * **Seti River Gorge**: The Seti River flows right through the city, often completely hidden underground in deep, narrow limestone gorges. * **Protected Areas**: Pokhara serves as the gateway to the **Annapurna Conservation Area**, Nepal's largest protected area, which promotes a successful model of community-based conservation. * **Sustainability Initiatives**: There are growing grassroots movements banning single-use plastics around Lakeside and promoting clean-up drives along trekking trails.
