Janosikove Diery or simply 'Holes' is a nice and quite non-challenging hike through canyons and narrow rocky paths. You can see some of the 20 waterfalls on your way through 'Lower Holes', 'New Holes' and 'Upper Holes'. To help you on your journey there are many ladders to climb the interesting rock formations.
You can choose from a longer and shorter trail; longer trail being the most beautiful one.
'Upper Holes' are inaccessible during winter and heavy rains.
Families with children often hike this trail though it's advised not to go with children to Maly Rozsutec.
On weekends the trails are usually crowded, so it's better to go on a week day.
