Hello, I'll be staying for 3 nights in Graz, arriving at 8 PM on my first day (Sunday) in July. I will thus have 2 full days - Monday and Tuesday for Graz but I plan to visit Maribor during one of these for a couple of hours as I've never been to Slovenia.
On day 3, the Wednesday I will probably take a 10 AM-ish train to Vienna to go to Bratislava where my Wed/Thu night is booked. This trip will take about 4 hours but passes through the Semmering Pass, which is said is beautiful.
I wonder what would you suggest seeing in Graz for what is basically a one full day and a half if I decided to do a Maribor day trip?
I'm thinking of climbing or taking the funicular to the hill with the clock tower, probably visit the Herz-Jesu-Kirche church as it looks interesting. As I like Modernist architecture I plan to visit Reininghauspark and basically spend the rest of my time there people watching. Is that a good plan? anything else I must at least see from outside? Thanks!
