American planning to visit Tajikistan this December. I just have a few questions!

Hello! I am a 19 year old male planning to visit Tajikistan this December, just curious on how difficult it would be to get by in the nation as I travel considering I don’t speak Tajik or Russian.

I am spending most of my time in the capital, but I was wondering if there was any service that could take me to explore the Zarafshan mountain range as well as go horse riding.

Also wondering how readily available transportation services are. Mostly taxis, buses, and trains. Is there an app you all use to call a taxi to get around? Thank you all so much!
