I left London about a week ago and have had a fantastic time covering the 2000 miles to the massive island of Krk in Croatia. So far the route's been: London (eurotunnel), France, Switzerland (SE from Davos was amazing), Italy (Dolomites and Marmalado in particular were excellent, Slovenia, Austria, Slovenia again (Bovec region is great) and now Croatia. I think today's my sixth day.

And to my current dillemma: At some point yesterday I had some vehicle documents stolen from a pannier. I keep all the important stuff beside me at night so it must have been whilst stopped at a petrol station or cafe... God knows where! The result: I still have my passport, UK driving licence (and paper counterpart), UK insurance document (Ebike) and tax disc. However, I no longer have my V5 vehicle registration, no MOT and no green card.
Thankfully I'm in Croatia where no green card is required but the vehicle registration is much more of an issue. So far I didn't have to produce any documents until the Slovenia-Croatia border where a wave of a passport was all that was required. So that would suggest that I could just backtrack my route and as long as I have no accidents and no police stops then it should be fine. But a bit risky!

I was hoping to continue south to Dubrovnik, pop through Bosnia to get to Montenegro (Serbia) to see a friend. What are those two border crossings like? Are there minor borders there where its possible to slip through without checks?

I don't fancy the long retracing of my steps so far and have a better alternative: to continue down to Dubrovnik, catch a ferry (as a foot passenger) to Kopor in Montenegro, see my mate, back to Dubrovnik and then catch a ferry with the bike to Italy. At least I'm then back in an easier EU country to deal with things.

So... any tips on the Croatia-Bosnia and Bosnia-Montenegro (Serbia) crossings?

And can a UK embassy do anything about a stolen V5?

Cheers,
Charlie
