Rationale: Saudi Arabia’s optimal is above 11, and even though the tourist numbers are mainly pilgrims and the territory is largely desert, a 9th region is warranted.
Al Baha, Asir, Jizan, Nazran
This region will be split into two. Al Baha and Asir (Abha) is where the ‘old’ region remains. Jizan and Nazran make the new region along with a very small southern corridor of Asir to adjoin the other two regions: you will need to mark this region as visited to claim it.
