Yes, there are water sources available along the Annapurna Circuit trail, including streams, rivers, and taps in villages. However, it is recommended to treat or purify the water before drinking it. The water from these sources may not be safe to drink directly due to the risk of waterborne diseases. You can use water purification tablets, water filters, or boil the water for at least three minutes to make it safe for consumption. Alternatively, bottled water is available for purchase at teahouses and shops along the route, but keep in mind that it may be more expensive and contribute to plastic waste.
