I will be traveling to Slovenia as a first-timer for a short 4-night trip before a conference in Zagreb in early September 2025. Although the first 2 nights will be spent in Ljubljana to recover from jet lag (flying to Zagreb from the eastern US), I'm considering a few different options for the other 2 nights. I will be traveling solo and enjoy both history and nature. Which of these 3 options below would folks recommend? Also, when does the "rainy season" hit the northwestern corner of Slovenia?
Option 1: Two Nights in Ljubljana, Drive to Plran, followed by 2 nights in Kobarid, skip Logar Valley
Option 2: Two Nights in Ljubljana, Drive to Logar Valley, followed by 2 nights in Lake Bohinj area, skip Piran
Option 3: Two Nights in Ljubljana, Drive to Lake Bohinj area for 2 nights, skip Piran, skip Logar Valley
Thanks in advance for your feedback!
