Slovenia Waterfall Sum at Vintgar

Waterfall Sum is a beautiful waterfall at the end of the Vintgar gorge near the popular lake Bled in Slovenia. It's about 15 minutes away from the lake by car and it's a really nice walk from the parking space into the gorge, walking beside or over the river.

You will probably need an ND + polarising filter and combine both to get the long exposure for the waterfall and the reflections out of the foreground to get more of the details in the river. Keep in mind, that combining multiple filters can produce vignetting depending on your gear, so just make sure that the corners aren't black.
It's also a good idea to take multiple shots without moving the tripod and paying attention to the bridge to make sure, that you have every part of the bridge without people, so that you can combine the images later on.
You should also have sturdy shoes, because the stones are pretty slippery.

Leave your car at the typical parking spot at the entrance of Vintgar and walk the tour through the gorge, which takes about 30-60 minutes, depending on the amount of people and the time you stop to enjoy the nice views. If you don't want to walk and pay the entrance, you are also able to enter the gorge from the other side. The waterfall Sum is located just beside this part, so you wouldn't even have to pay (4 Euros for adults, parking is free) for it.
If you walked along the gorge, you need to stay at the right side of the house just before you walk over the last bridge. There are stairs down there and after passing another bridge you need to walk to the left through a narrow path. The waterfall you can see in the image is the one which is just beyond the last bridge. It looks pretty small on wide angle images, but it definitely isn't.
