To travel between Sumdo in Spiti and Rekong Peo in Kinnaur, foreigners need an inner line permit. These are obtained easily in Rekong Peo (₹400) and Kaza (free), or somewhat less rapidly in Shimla (₹500 to ₹600). Note that a few Asian nationalities, including Chinese and Taiwanese, cannot get inner line permits but must apply for a special permit from the Ministry of Home Affairs in Delhi.
