Chitkul is the last village of India, so there's nothing after that but Chitkul itself is really beautiful place to be. Just before that there is Sangla which you'll be crossing on your way to Chitkul. You'll be taking the turn for Chitkul near the Karcham and the another road from road will be going towards Powari where a road will be going to Reckong Peo and Kalpa. Do visit Kalpa and enjoy the apple trees. The apples are really different from what you'll get in any Urban area. There'll be red apple and green apple both.
