Hi Akash,
There are many good suggestions on this for where to go. But i think you should go solo with a group once. Group travels are a bridge between travelling with someone known and travelling all solo. You will have around 10-15 strangers in a group and you will get to meet new people too. This was a suggestion from one of my friend for my first solo trip to Tirthan valley and i am glad i listened to my friend and went on that trip with 15 complete strangers because that was one hell of a memorable trip.
