Bay of Kotor. The border between Bosnia and Montenegro is at 900m above sea level. But right after this mountain you can just roll into Herceg Novi at sea level. I spent the night in my tent on a cliff right above this coast town. Waking up the next morning I had a fantastic view of the sunrise since everything below me was covered in clouds while I was above them.
Next I was cycling through a natural world heritage site - the Bay of Kotor. I had to wait a bit until the fog was gone but it was totally worth it. The whole bay covers around 30km and you get some stunning views of cliffs and medieval towns. I'll let the pictures down below speak for me.
Next up is a country I have been really looking for to cross on bicycle from north to south: Albania.
