The preparation itself was actually an adventure on its own.
Searching the internet for information showed quickly that there was not that much information available. Browsing traveller blogs proved to be a better option.
Because the country map ordered online took a while to get delivered, google maps and old school paper & pencil was handy to plan our itinerary.

Bisjkek, capital city of Kyrgyzstan and our first night of a 3 week adventure. Next morning, after the reception of the rental car we headed for Issyk Kul lake. A little beauty of 185km long by 60km wide @ 1600m altitude.
Imagine laying on a beach with mountain view, mind blowing.
But first we stopped to visit the Burana tower. A minaret dating from 9th century surrounded with hundreds of balbals and petroglyphs.

Train spotters will have to be patient. Trains are a singularity in Kyrgyzstan. This is the only one we came across.
Later on during our holiday we learned that they’re only used for freight. (barely 370km rails)
