Guide in Slovenia

We have had lots of luck hiring a guide through Toursbylocals.com. We have used gides in Spain, scotland, Ireland, croatia, and even Cuba off a cruise.
What I like about this website site is that you get to read the guide’s profile, see the dates they are free, see their price up front, and read if they have other tours. If it is private, which many of them are, you can customize the day to fit your plans.

In what part of Slovenia are you looking for a guide?

We will be in Ljubljana but would like 2 full day trips.

Have you tried Slovenia Explorer? I haven't used them but I see them talked about on here quite a bit. Im looking at using them myself.
