Conclusion:
Latvia is also a beautiful destination, especially the capital Riga and especially the city of Kuldiga! All in all we stayed 10 nights in Latvia and also have the feeling to have seen as much as possible here. If the weather had been better during the last days, we would surely have explored the Gauja National Park even more. But so we relaxed a bit and planned our trip a little bit further. We also have a clear travel recommendation for Latvia!
