The Ceahlău National Park, including the 1907m high Ceahlău Massif, Moldavia's most impressive peak, spreads out for some 77 sq km and offers great hiking and stunning mountain views. The range is part of the Eastern Carpathians and climbs dramatically to the west of the sprawling artificial Lake Bicaz (Lacu Izvorul Muntelui). An early-morning photo from the peaks out over the misting lake in the distance is the stuff of Instagram legend. Access the park via hiking trails that fan out from bases in Izvorul Muntelui, near Bicaz on the southeastern side, or from Durău in the north.
