Albania / Montenegro / Kosovo Off-Road Routes

Hi, I'm looking for advice on riding in these areas.
I've put together a tentative route which can be found below.

I have a strong preference for non-paved doubletrack and singletrack riding. We will be wild camping or staying at simple guesthouses.
It's rather difficult to find information and exciting routes in this region.

Have I missed a gorgeous ribbon of singletrack I should add?
Anything else I should know?
Thanks.

I was there last year - further north to where you're planning, in Montenegro - Durmitor National Park area. It was amazing and all I can say is that I wish I'd been on a bike rather than a hire car. You'll have a ball.

We hiked from Peje to Theth along the peaks of the balkans trail last year, which intersects which some of your route, so I may be able to help with some questions..

Much of it was very rideable singletrack or gravel, but a few parts definitely weren't - steep, scree, boulders, snow in june.

I'll see if I can remember more, but Albania was definitely rockier, with more grassy tracks in Kosovo/Montenegro.

Either way it was all so beautiful.

There's this race happening there this year, did you check out their route?

Might have some pics of sections of interest

Also, Lost Dot's Accursed Race route might be worth looking at.
I've only been there during TCRs so mostly road.

did you get any further with your planning? Just started looking at a trip to get both Montenegro and Albania in, thinking the Trans Dinarica: Accursed Mountain Circuit but would like to add Durmitor National Park (sounds like a lot of others love that area).

Trying to see if I can get there and back from London by train without losing a week in travelling too :(
