What's there besides hiking?
Are there still Jewish communities there?
There are Jewish communities in Tashkent and Samarkand. There are also very small communities in Bukhara and Abidjan maybe more.
Bishkek has a community and a shliach.
Dushanbe in Tajikistan has a few Jews and a center that might be hard TH find (was donated by the presidents BIL when they destroyed the shul to build the presidential palace).
Turkmenistan has a few Jews but nothing organized as far as I know.
Kazakhstan has several Shluchim in several cities but I’m not sure if it’s currently possible for foreigners to enter.
