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.
