Hello, and thanks for this wonderful and helpful site!
In late August, I will be on a grand voyage from Ljubljana to Istanbul. As part of this trip, I will be traveling between Sarajevo and Sofia, Bulgaria. Unfortunately, I do not have time to go up to Belgrade or Novi Sad. Because of time constraints, I only have one day to spend in Serbia! Can anyone suggest a great place to stop and rest in Southern Serbia, between Sarajevo and Sofia? Any great national parks, villages, or cities? Is Nis the best place to stop?
Note that I will be traveling by bus and train, so anywhere you suggest must be reachable by bus or train from Sarajevo and Sofia.
Thank you so much for your help! I am sure that I will love Serbia and I'm looking forward to coming back with more time to give the country the attention it deserves!
Cheers,
Gabriel
