No visa required for German tourists staying 90 days max. Carnet de Passage not required but Kyrgyzstan vehicle customs declaration recommended. Border crossing with our truck without any problems in Bishkek in 15 min at no cost. No problem to store the truck for some time.
The only Central Asian country with a „real“ Parliament. People quite friendly, police not affecting foreigners in any way, no bakshish. But beware: Extensive speed control all over.
Good restaurants scarce, Hyatt in Bishkek the best one, others not recommended. Avoid tap water, fish and salad with sensitive stomach.
