Sichuan's Tibetan areas — the heart of Kham, and part of Amdo — cover about 235,000 square kilometres, roughly the size of the United Kingdom. They are not a substitute for Lhasa. They are the same civilisation, at the same altitudes, without the permit regime.

Permit rules are set by the Tibet Tourism Bureau and are checked before every quote. Nothing here is a workaround — the two regions simply have different rules.
