Next morning we started to trek down to Nauradhar. Start early so that you can reach by 2 pm or earlier to Nauradhar. Post which you can get a bus to Rajgarh or Solan directly. It will take 3.30 hours approximately. From solan, you can get a bus to Chandigarh and then to Delhi. Or if you want to enjoy an evening in Shimla (3 hours from Solan) as we did you can pick a bus to Shimla to enjoy the evening at Ridge and Mall road. We then took a bus from Shimla at 11 pm to Chandigarh, which dropped us around 4 am at sector 43 Chandigarh bus stop. From there take a Chandigarh state transport bus to sector 17 stop to catch a bus to Delhi.Pro-tip: Start as early as possible to trek upside so that you have enough time to plan for the day. You can get a good stuff easily on the peaks.
