We will arrive Sofia 23 April and spend approximately 3 weeks in Bulgaria before leaving for Romania at Ruse. About 3 weeks later, we will re-enter Bulgaria through Vidin and leave about 10 days later from Sofia on 16 June.
The second 10-day stay in Bulgaria will be devoted to hiking in the Rila and Pirin. We save this for last to avoid as much snow as possible.
The first three-week period, we would like to see the following (not in order):
Preobrazhenski Monastery (hike)
Some of this is self-evident, but I can't figure the best sequence, particularly in the middle of the country. We will use public transportation only, and are low-budget.
I would also like guidance as to where we might inject hiking to small villages.
