Definitely I enjoyed the diversity of the trip. The combination of modern (Nur-Sultan) and historic cities (Samarkand, Buchara). The different landscapes with wide steppe (Kazakhstan), green rolling hills with clear rivers and forest (Kyrgyzstan), the high plateau lakes (Kyrgyzstan, Tajikistan) and the rough mountain ranges and valleys (Tajikistan). The combination of comfortable hotels (cities), yurts and basic homestays. And of course the different cultures in the region, becoming obvious for travellers by customs, food, language, ethnics including obvious facial features which are more evident than I have naively expected based on the common history of these countries in the Soviet Union.
I would make only few changes regarding the itinerary. Maybe one more day in Osh and Iskashim for regeneration and instead skipping the the mountain area around Iskander Kul and the Seven Lakes, which, despite the beautiful scenery, fell a bit behind after the time in the Pamir.
For anyone who loves long road trips in epic landscapes with a touch of adventure, this trip is heaven. Of course you shouldn't mind long days on bumpy roads, basic accommodation with no hot or cold showers outside the bigger cities, and also occasional stomach problems are hard to avoid, especially in the Pamir region. Nevertheless, the food was almost always tasty and even the most basic accommodations were clean, and lovely hosts made up for missing comfort. Locals were friendly all over the trip, but language is an issue. Beside the local languages, Russian is widely spoken, however English only by chance. So communication with locals was mostly limited to gestures and smiles or translation by our guides. Although by far not a cheap option, but doing this trip as a private tour with driver and guide proved to be right for us and of course you get what you pay for.
Therefore: a big THANK YOU to our guides (Sabina, Diana, Mohammed, Zoyir) and drivers (Damir and Sharif) on the way, which all made this trip memorable and did a great job bringing us their countries and local culture closer and enriched the trip with their own personalities. Special thanks also to Luca and Aijan LΓ€sser from Kalpak Travel, who helped us to create that tailor-made tour and organised it in a perfect way. Everything worked perfectly from start to finish.
Nevertheless, we also met independent travellers, even mostly on bikes. So of course it's possible if you bring more time and have a special adventurous spirit. In Uzbekistan, we have seen bigger tour groups, but in the other countries only few small groups up to maximum ten persons. This all comes with obvious advantages and disadvantages. So, different ways to explore Central Asia. If you are interested, take the one that suits you best and go for it, you won't regret visiting these diverse and fascinating countries.
