The picturesque town of Zacler is an ideal starting point as it has a lot to offer. However, it is not the only place to start your crossing of the Krkonose Mountains. The Stachelberg Fortress is equally attractive, or you can start straight from the more distant Trutnov.
The first distinctive peak is the Dvorsky Forest (1036 m), whose mysterious atmosphere is best enjoyed on foggy autumn days or after rain; the view from the Snow Houses is at its most beautiful in the morning during an inversion. You can admire the western side of the ridge from the viewpoint at Rýchorská bouda.
If you want to admire the beautiful Krkonose timbered houses, you can walk through Horni Alberice or you can descend from Rychorsky Cross to Dolni Alberice. Don't be in a hurry, the eastern Krkonose Mountains are extraordinary.
