Tips from the Community
Hello! And welcome to the Julian Prealps Natural Park. To enjoy your experience to the fullest and with respect, we invite you to follow a few simple rules—they're our way of saying "thank you" to this extraordinary environment: - Bring home memories, not flowers: take all the photos you want, but leave plants, fossils, and any natural artifacts intact. - Dogs are welcome, but always on a leash: this way you protect the wildlife and themselves. - No wild camping: nature rests here at night, just like you! - Silence, the mountains speak: no loud music, shouting, or bright lights—let the sounds of the forest be your soundtrack. - Stay on the trail: walking off-trail damages delicate habitats. - Hunting is prohibited: animals live peacefully here, as they should everywhere. - Watch out for ticks: ticks are present throughout the Friuli Venezia Giulia region, so it's important to learn about prevention and protection techniques! Don't throw away your trash: everything you bring with you (snacks, bottles, tissues, etc.), take it home. The mountain is not a trash can. Nature thanks you! And if you need information, write to us at info@parcoprealpigiulie.it

A pleasant journey back in time: "Mostra Miniera del Resartico" (Resiutta Mining Exhibition). In 1844, Carinthian entrepreneurs began producing beer in Resiutta, which was then part of the Habsburg Monarchy, using the excellent water of the Resia River. A tunnel was dug for this purpose, which served as a storage and cooling room for the beer. By 1900, the resources of the icehouse were no longer used, and the icehouse remained empty. In recent years, the tunnel was rediscovered. Restoration and research work now allow visitors to retrace the course of history and visit this special place. The tunnel itself features information panels that illustrate the history of this place and beer brewing in Resiutta.

It is a small building which now offers protection for 2 - 3 people, but this functioned as an observation post during the Great War. From the small windows you can easily observe the mountains to the east, the northern flank of the Montasch and the Val Saisera valley below, which was then the border with the Austro-Hungarian Empire.
