I have a trip for about 7500km planned for the first 3 weeks of September.
Going trough 16 country's, mostly Balkan, it's gonna be a tough planning because news about expectations about travelling and long term plans are hard to find.
There is no planning other than the route with only a few waypoints as a must see, so even the route is not set in concrete witch can come in handy if there are still lockdowns by then.
Also had a base route ready for a trip to the north what was on the schedule for 2 or 3 years from now but i think i go work that one out as a alternative for this year if the Balkan trip will be unclear.
The Scandinavian countries are planning to open the borders in around mid of July, if it is definite in the beginning of August it is early enough to change the plans. The Baltic countries are already open between themselves so i expect an opening for the rest of Europe in the next few months.
