Lake Bohinj vs Piran

But from Ljubljana you can do Bled, you can do Bohinj, you can do Postojna + Predjama. All of it is amazing.

Also, as a general suggestion, look for accommodation in Bohinj instead of Bled and Cavtat instead of Dubrovnik. Way easier on the huge crowds and equally huge prices.

but honestly lake bohinj was way more chill and less crowded, you can take a bus from bled.

It is nice to stay in Bohinj for a couple of days. From there, you can do a hut-to-hut hike, or you can be stationed in Bohinj and do 1 day hikes. Bohinj/Bled It is a very good starting point for hiking, as you can see here: [https://www.altitude-activities.com/mountaineering]

You could easily do 10-14 days just in Slovenia. Ljubljana as a base, day trips to Bled and Bohinj, few days in the Soča Valley, maybe Piran on the coast if you want something different.

If we're talking 8-9 days I'd suggest 5 in Ljubljana as a base for day trips and then you could do 3 days by the coast in Piran or you could go east to Maribor, which is also really nice.

Hope you figure out a way to get to Piran, it is beautiful.

Piran and Rovinj are nice.

You can stop in Piran shortly on the way to Croatia.
