Visitor Reviews of Ostrý Grúň Kollárová
- Csaba from Hungary writes:
Csak jókat tudok mondani a síkozpontról. Színvonalas a büfé és még magyarul is tudnak. A pályák karbantartottak állandóan hóágyúkkal frissítik a havat. A parkolók közvetlen a pálya mellett vannak és a teljes időt ki lehet síelásre használni felesleges sorbanállások nélkül. Az odaút is csak fele mintha a donovalira mennénk. Örülök, hogy rátaláltam erre a síközpontra. Ajánlom mindenkinek. Imádom, hogy azóta nem kell 3-4 órát autóznom.
