Any attractions from Ljubljana to Bled and bohinj

I recommend you take the route through Škofja Loka to Bohinj. Škofja Loka is worth a short stop, but the real attraction is the scenery you will see as you continue from there to Bohinj. Some of the most stunning vistas I've seen anywhere!

Not from from Bled is the charming town of Radovljica. The main attraction there is the Museum of Apiculture.

Yes, I agree Škofja Loka and the scenic drives on from there. I drove via the mountains through Drazgose, Jamnik, and Kropa down to Bled (I think you pass near Radovljica on the way to Bled). The route to Bohinj is a little different - I didn't take it. The church at Jamnik is a dramatic foreground to the mountains behind - I have that picture hanging on my wall at home. There are lots of little stops along the route (even though the road is narrow, you can usually find a pull-over). So give yourself time to drive at leisure.

Last time I visited Škofja Loka, there was free parking for a few hours across the street from the bus station (at the edge of the old town) in the lot where the stores are - but maybe it's free parking on Sundays. Signs should be clear. There is a little visitor's center as you approach Škofja Loka from Ljubljana, but it may be closed on Sunday.
