how hard is solo travel without a car in Kyrgyzstan? (going to Uzbekistan also, route attached)

Hi,

thanks in advance for any help. So I’d like to do a joint trip to Uzbekistan and Kyrgyzstan in June. I attached an itinerary below. It seems like Uzbekistan is pretty straightforward since the most common tourist circuit is bigger cities. The Kyrgyzstan part is more concerning. Are there public transportation options? Are tours generally needed if you’re not renting a car. Any advice or help is appreciated. I have the itinerary below and would love feedback on it also and what to take out and what to put in. I can add days and I like culture, nature and hiking.

Day 1 – arrive in Tashkent to khiva

Day 2 – Khiva – night bus to Bukhara

day 3 – bukhara

day 4 – bukhara to samarkand

day 5 – samarkand

day 6 – samarkand to Tashkent (night train so 2 days in samarkand)

day 7 – Tashkent

day 8 – tashkent to Bishkek

day 9 – day trip to ala artscha

day 10 – Bishkek to son kul

day 11 – son kul

day 12 – son kul to kok kiya valley

day 13 – kok kiya valley

day 14 – kok kiya valley to issyk kul

day 15 – issyk kul

day 16 – issyk kil to karakl

day 17 – 19 or 20? some sort of hiking in karakul

day 21 or whatever it is – karakul to Bishkek

day 22 – flight out

Any advice or help is greatly appreciated. Thanks!
