Mainly depends on from where you want to travel. mostly around your area for 3-4 Days will be in budget. long distances make travel long and Budget will go higher.
Hey Ayushi,
Depending on your current location you may choose following options :
1)Delhi -Jaipur, Auli, Rishikesh, Mussourie, Parvati valley,Kullu-Manali, Kedarkantha trek
2)Mumbai -Goa, Wayanand, Allepay, Banglore, Coorg, Munnar, Kumarakom
3)Calcutta — Gangtok, Darjeeling,North Sikkim, Shillong
Acc. to my experience i would suggest choose between these :
1)Jaiselmar
2)Goa
3)Rann of Kutch
4)Kedarkantha trek
Hope this would help you.
