Go now . Its best time till Mid May. After that monsoon will start and landsides are there . This time suitable for Rafting and visit all places in pleasant weather.
Hi Svathi, May to June is quite hot at Rishikesh, when temperature touches + 35 °C. The best time for river rafting is from late September - October to mid November, and then the best time to visit Rishikesh is from early March - April to first week of May.
If you can manage upto mid april then its ok... still you will enjoy it the most in the season of winter.
please try to avoid mansoon in any case because volume of water increases too fast and also river rafting is closed during this season. many camps near bank of ganga also shut down during mansoon.
