Hi Jim
Its me Big Tim. Sorry I've not replied earlier but I've had a very hectic week.
As others have said we did indeed visit Slovenia and Croatia this Summer. We travelled out at the end of July and returned home at the end of August so we were away for 5 weeks in the Peak summer season. We travelled via Norfolk Lines Dover to Dunkerque and then drove on the motorways through France, Belgium, Luxembourg, Germany and Austria to reach Camping Bled, our only campsite stop in Slovenia. We took 3 days actually driving down stopping at 2 campsites on the way. Our return mileage for the trip, from Merseyside, was 3303 miles!!!
You can read my review of the Camp Bled here:

As you can see we had mixed feelings about the campsite but it would probably be better if you were not going in the Summer Peak. When, and if, we visit Bled again I would definitely check out Camping Sobec which has already been mentioned.
Whilst we stayed at Camping Bled we visited another campsite. This was Camping Zlatrog which is actually on the shores of Lake Bohinj. This lake is a few miles from Bled and very picturesque and unspoilt as has very strict no-building rules for its shoreline. We walked through Camping Zlatrog to catch the "Tourist Boat" which travels along the length of the lake. The tourist boat is the one in the video. When checking the name on google I found this "You Tube" Video

The video does, however, show how Zlatrog at its best and I think off peak. When we walked through it was VERY crowded, especially on the lakeside where 'vans were packed in with hardly any space between them. The campsite was generally a bit untidy looking as there were camping units of every description squeezed in every space. The loos were, however, very clean and modern, I sneaked a peek as we passed. It DOES have a stupendous location on the shores of this beautiful lake and I would consider staying there if I were going OUTSIDE peak season.
We did not stop at or visit any other campsites in Slovenia as we then travelled on to Camping Galeb at Omis south of Split in Croatia and only passed through Slovenia briefly on the way home.
I did post a few times on Practical Caravan Forum giving progress reports on our trip and you will be able to read these if you look back in the "Overseas" section.
We did NOT, by the way, book ANY of our sites on this trip, we rarely do. Even though it was high season we just phoned ahead when we got near and were only disappointed once.
If you have any specific queries please post again and I will try to answer them.
Kind regards
Tim
