Yes, rubles can be exchanged, but the exchange rate will be less profitable than when exchanging EUR

Rubles can be exchanged for crowns on arrival in Prague right at the airport. Also exchange offices are found in hotels, railway stations, on popular tourist routes. But, as a rule, the rate at them is unprofitable. In addition, often on the posters in large letters a good course is written, and below it is a postscript that such conditions exist when exchanging large sums.

The best are the Arab exchangers in Prague, they need to be sought in the Wenceslas Square area. Exchange services are offered by Unicredit Bank, but it charges a 2% commission. If you are approached by a decent looking person on the street and in Russian will offer to exchange rubles for crowns, it is better to refuse, since it is most likely a fraudster.

You can withdraw money at an automated teller machine by automatically exchanging.
