Ali Chur is in the Pamirs.
Ali Chur is a small village on the Pamir Highway (M41) between Murgab and Langar. Ali Chur lies high in the pamir mountains on a windy plateau just below 4000m.
You may see many old cars, including old Ladas, on the side of the road.
Ali Chur has a couple of homestays, some of them with a signpost. Most homestays close from November to March, so ask around.
