Looking for Slow & Uncrowded Solo Trip Ideas in Himachal/Uttarakhand (April 11–14) — Open to Travel Buddies

I’m planning a 4-day solo trip from April 11th to 14th and looking for peaceful, less crowded destinations in Himachal Pradesh or Uttarakhand. I’ll be starting from Delhi and don’t mind using the first and last days for travel to maximize my time at the destination.

My budget is around 15k.

I’d really appreciate suggestions for places that are ideal for a slow, relaxing experience rather than busy tourist spots. Also, if anyone is planning something similar around the same dates and would like to join, feel free to connect!
