Březina nad Jizerou - Studený průchod - Drábské světničky - hrad Valečov - Valečovské skalní byty - Mnichovo Hradiště
A hilly route, but not so long, so it's ok also for kids or people not used to walk very much. There is a buffet at Valečov castle. Many nice views along the route, beautiful rocks everywhere. You can end the trip by visiting the castle in Mnichovo Hradiště.
