This is the SLovak side of a 3 Nation 'National Park'. From Nova Sedlica, where there is a single but very well priced penzion, you can walk up one of 3 hiking trails, depending on how good your legs are feeling, and head up to Kremenec. This peak is where the Slovak, Polish and Ukranian borders meet. It's quite a tough hike, total ascent over 1000m, but its all through natural unmanaged forests and is a beautiful hike with a rewarding view over three countries for your efforts. You can relax in the evening with good food and simple accommodation (but clean and good) with a pint or two of Slovak beer and maybe a Hruska or two (pear Alcohol, and dangerously nice!!)
