Lars asked me to write somethig about slovenia. I will do my best and i will try to answer all your questions.
1.entering fron Karavanke tunnel.
On the first exit leave the avtobahn and follow directions to Ratece. After 20km you will see directions to Planica-ski jupms.
Before Planica in Kranjska gora and there starts one of the best alps road, road to Vrsic and Trentarska dolina with beatuty of river Soca. That road will lead you to Gorica and Goriska brda. From there you cen go left towards Ljubljana or continue to lans of Kras to Postojna or to coast.
Other route is from tunnel to Bohinj and Bled, waterfall Savica. Near Bled is motel Leski dvor, very nice, not expensive rooms, good food. From there you can go to Ljubljana, with a coffe brake in Kranj, old town with hill named Smarjetna gora. From Smarjetna you can see almost whole central Slo. From Kranj you can turn right to Skofja loka or go straight to Ljubljana.
In Ljubljana you must see old city center. We have traditional wednesday meating on Presernov trg. You can sleep in Bit center in Stepanjsko naselje. It is cheep and nice. If you want to stay in city center i prefere Hotel Park.
From Ljubljana you can go to Kocevje, nice bikers road. From kocevje you will need less than two hours to Rijeka or Krk bridge.
You can also go to Koper, but don't go n bahn, use old road. It is a well known bikers route.
If you aren't directed to sea, turn in Lj towards Celje. Use old road. Near Celje is Vojnik with a beautifull lake. From Celje you can go to Logarska dolina or towards Maribor. Near MB is Pohorje and Rogla. From MB you can go to Sentilj or to Murska Sobota. If you go to MS, stop in Radgona and find Motel pod Kostanji. Best food and cheep roams.
2. If you will enter Slo thru Lobel tunnel or Jezersko you will enjoy on your bike. From there you will get on the road to Kranj or Bled.
3.When you're in Slo stop in Postojna cave, Cerknisko jezero, Predjamski grad, Soline, Piran, Bohinj, Bled, Pokljuka, Planica, Kranjska gora, Kranj, Ljubljana...
I reccomend use of Autoroute 2002. If you need more info just ask. Write me your wishes and i will try to organize or just to give you an advice.
