It appears that Slavoj is actually a ski resort located in Železná Ruda, Czech Republic. However, it's not explicitly mentioned in the search results. After reviewing the results, I found that the resort is likely referred to as "Špičák" or "Spicak" in various sources. The resort offers 8 km of pistes at an altitude of up to 1200m, with a lift pass that provides access to the area. It's considered a great destination for beginners and families, with a variety of blue and red slopes.
