18 km day hike to Snezka

An 18km hike with a couple of friends and their friends to the highest mountain in Czech Republic: Snezka, 1603m.
After a third of the hike the friends of my friend had to go back, they over estimated the difficulty of this hike.
Along the route was occasionally some snow and at the peak as well.
Other then that just stunning views along the whole way.
