From Horni Paseky, after a view of the church tower of Mokriny, the trail slowly but steadily ascends through the high forest to the source of the White Elster (Pramen Bily Halstrov). In the final section of the trail, follow the Czech name of the spring. The spring itself is located somewhat off the hiking trail. It is accessible via a wooden boardwalk from the rest area. Don't miss the opportunity to browse the spring book and take a photo of yourself.
