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 philosopher's path leads through the Wolfsschlucht. Over several cascades the water of the Markbach runs about 500 meters through the gorge. You can walk along bridges and steep steps and watch the falls.
Beautiful path up to the eastern summit of the Kampenwand... you have to climb a little and should therefore be sure-footed... it's amazing how many inexperienced hikers venture up here thanks to the nearby cable car.
