Can you please suggest me accomodation as well.Day 1: Chandigarh to Sangla, long drive so start early in the morning.
Day 2: Visit Chitkul and then head to Kalpa for night stay. Visit the suicide point and do some sightseeing and travel up to the suicide point. Most of the places worth visiting in Sangla, Chitkul and Kalpa are short treks, so unless you do it, you will be able to cover both the places.

Day 4: Tabo to Kaza, en route visit Tabo Monastery, Dhankar Monastery and Pin Valley (Kaurik Monastery and Mud Village).

Day 6: Kaza to Sarahan or Rampur, long day so start early in the morning.
Day 7: Sarahan to Chandigarh, alternatively you can break the journey en route.
1 day kept as buffer. It can be used at Sarahan or alternatively you can stay at Sangla on day 2 and visit Kalpa while coming back.
