Solo female traveler in Slovenia

I’m going to Slovenia for a week as a 30 year old female solo traveller. It will be my first time traveling alone out of my own country (the US). I love spending solo days swimming in natural water (waterfalls, swimming holes, rivers, lakes) and seeing culture / shopping/ wandering. I tend to dislike cities, but enjoy small cultural towns. I’ve been looking into lake bohinj and soca valley which look great. I think I want to skip lake bled for something else. I’m not sure what else to do or where to go. Looking for advice on places to swim, explore, hike and shop, also safest areas to stay as a woman. Thank you!!!
