Krasna Lipa is a beautiful village area. My favorite is to start from the North in Rumburk. There are some nice peaceful roads, good quality, forest, decent visiblity, through to Krasna Lipa. From Chribska south to Ceska Kamenice is a simply phenomenal stretch of road. Mostly descending down, with very good road quality, some very nice corners, and beautiful visibility and view on the valley below. Must try.
There are many nearby interesting roads to link this stretch up with, either to west to Hrensko, north to Germany, southwest to Decin, east to Liberec, or of course through Duba to Prague.
One of the best roads near Prague
Approaching slapy from the north, theres a nice road with good visibility through a forest. The eastern section across the damn has great twisties with decent visibility, less traffic and good road surface.
Another nice section for a quick ride from prague or to string together with beroun/karlstein or to head up on the eastern side of this route towards the 1.
Nice section to string in to a Karlstein and / or Slapy route.
