A week+ journey or a short 3-day tour — or anything in between
We have bikepacked this circular route from Belgrade and back twice — in December 2023 for scouting, and in May 2024 in a lightpacking tour — and are going again, for a supported tour, in May 2025 (but this time in the other direction).
The circle is highly adjustable — you could go from Sarajevo to Belgrade instead, do just one half (either of the two) or even their shortened versions: the segments Belgrade—Valjevo and Belgrade—Sremska Mitrovica can be traversed by train in just 1–1.5 hours.
So, this can be 3- or 4- or 6- or 8-day trips — and each in 4 versions — making 16 possible combinations. Actually, Valjevo—Sremska Mitrovica (or reverse) is also a 1-day route fully scouted by us, so add 2 more 7-day non-full circles from Sarajevo! 18-in-1 it is.
