Okno Ohniste (Fireplace Window) is the largest arch in Slovakia at about 66 ft high. The lower half of
the opening is obscured in this photo. The arch is in a limestone cliff west of the summit called Ohniste
in the Low Tartra mountains. The arch is at an altitude of about 5000 feet above sea level and the trail
to it rises about 2700 feet. The hike to the arch took about 3 hours and 2.5 hours back. Photo by Ray
Millar. Although there are trails to the arch, Ray recommends a
guide for this trip.
