Rishikesh has a plethora of ashrams, yoga centers, and adventure sports for which you can carve out a few extra days from your schedule. If you are staying longer, you can visit the Beatles Ashram, attend some classes, and learn about the history of Rishikesh. If you have less time, you can skip visiting the Neer Garh waterfall. Make sure to wear comfortable walking shoes and carry a sunscreen and a water bottle.
