Southern Šumava is a varied section going from the lowlands to the southernmost point of Czechia, only to take you slowly uphill where the mountain range starts. From the village of Přední Zvonková onwards, it shows its true colors and becomes a regular mountain section. At the end of the section you will be rewarded with a beautiful crest trail from Smrčina to Plechý.
You can find this section in the official app of the Czech Trail, FarOut:
