Hi akshay...if this is your first solo trip then you should probably think of triund if you want to go for a short trek as well on your trip.From delhi to delhi a 3-4 days trip should cost between 5-6k per head.
If you're looking for something nearby, Uttarakhand would be the best option for you. You can go for safari trips in Corbett National park - Ramanagar, Badrinath, Haridwar & Kedarnath if you want to visit some holy places, for river rafting you can go to Rishikesh, & if you simply want to enjoy a boat ride in a rapidly changing weather you can visit Nainital. But if want to explore more do visit Himachal, Ladakh, and the seven sister's too. Hope that helps. cheers !
There are plenty of options for your solo trip. I did my first solo trip to Pokhara Nepal, which itself was the best trip up until now. traveling solo gives you a whole new experience and a space to explore yourself. if you're looking for nearby options, triund trek, kasol, kheerganga, Joshimath, dharamshala are the best options. all the very best for it, would love to hear how your trip went! :)
Hey. Delhi is close proximity to various hill stations. The closest states to Delhi where you can enjoy the Himalayan views are Uttarakhand and Himachal Pradesh. In Himachal Pradesh, you can visit Mcleodganj where you can find a very laid-back vibe. There are plenty of cafes there, and you can also enjoy a visit to one of the sacred monasteries located in Mcleodganj. If you would like to challenge yourself, you can embark on the small, one-day trek to Triund. You can also visit Manali. The mall road of Manali has plenty of shops from where you can buy Pashmina shawls and eat the traditional Himachali dish, Siddu. Sightseeing spots such as Hidimba Temple, Manu Temple and Vashishth Temple are also located nearby. You can also choose to stay at Old Manali if you enjoy a more chill vibe with cheaper hotels. Jogini Falls offer an exciting and challenging trail if you would like to trek. Kasol is also located at a close proximity to Delhi. You can enjoy meeting new friends in the cafes of Kasol, stay at a budget hotel and trek to nearby villages such as Grahan, Tosh and Kalga.

Besides the usual sightseeing spots of Shimla such as Mall Road and Jhaku Temple, you can also explore nearby towns such as Chail and Kufri. Uttarakhand has also got plenty of towns near Delhi. You can enjoy a road trip to Dehradun-Mussoorie and enjoy a stay at a budget hotel. In mussoorie, you can visit the Gun Hill and Lal Tibba viewpoint. Besides that, you can also visit Nainital.
