How about Kaiyuan Travel’s Balkan Peninsula travel itinerary?

I followed Kaiyuan’s Balkan Peninsula travel itinerary. I remember the next day’s itinerary was as follows:

After gathering at the hotel in the morning, we headed to Bled at the southern foot of the Alps. Lake Bled was created by the geological movement of glaciers in the Alps. The melted water from the snow on the top of the "Three Heads Mountain" continuously pours into the lake, so it is called the "Ice Lake". Take a cruise on Lake Bled and look at Bled in the distance. De Castle and explore the monastery of the Holy Island in the Lake. Then go to the capital of Croatia - Zagreb, admire the Gothic architecture - Zagreb Cathedral, compare it with St. Mark's Church in St. Mark's Square, and experience the different church interiors and culture. The observation deck of Lotersac Tower in front of the Museum of Lost Love overlooks the old city. Overnight at a hotel near Zagreb.

That trip left a deep impression on me. The scenic spots are indeed beautiful, and some scenic spots are even more beautiful at night and in the evening.
