Hi Ankita, A budget of ₹15,000 is decent enough to enjoy your time with your friends outside Odisha. However since you haven't mentioned any areas of interest that you and your friends want to explore, I suggest you to look north of India to Himachal Pradesh or Uttarkhand or Sikkim or Shillong. While Sikkim and Darjeeling are nearby mountain destination from Odisha. The reason I'm suggesting only mountain is cause there are ample of sea beaches in Odisha and the only hill range is that of Phulbani range. Therefore, traveling to these mountains of Himalayas could be a different experience for you. Let me know at sudip.247@gmail.com if you need any help with planning the itinerary as per your interest. Thank you and happy traveling.
