India is such a big country it will be hard for you to decide which area to visit. Personally, I’ve been to India twice and did different two different regions because I wanted to take my time. Please note that traveling around India can be really tedious so it’s best to focus on one region, most especially if you don’t have the time.
If it’s your first time in India, I would recommend for you to visit the Rajasthan area. It’s super pretty and is very tourist-friendly. Of course, you don’t have to listen to me – it’s entirely up to you which regions to visit. Feel free to browse this list of the best places to visit according to travel bloggers who have traveled India extensively. Let me know which one you’re eyeing!
