The Gießenbachklamm is an easy going gorge. There are a few steps (just under 100) until you're up, so unfortunately not suitable for strollers. Otherwise very suitable for children.
No danger spots and entertaining. No entry.
The lake's outflow passes over a weir and falls over a small waterfall into the Kieferbach stream. This outflow waterfall is the only outflow of Hechtsee.
