Some say you haven't truly experienced Skaftafell until you've conquered the twin peaks of Kristínartindar. Standing at 979 and 1,126 meters (3,212 and 3,694 feet), the views from the vertigo-inducing summits, which are connected by a narrow path along a jagged ridge, are the best in the region, taking in the vast expanse of Skaftafellsjökull, Morsárdalur, and Skeiðarársandur. The trail to Kristínartindar is a challenging six- to eight-hour round-trip (approximately 18 km [11 miles]) from the visitor center, and only for experienced hikers. Access is usually closed from mid-September and over the winter because of snow, ice, and windy weather. Due to meltwater in the spring, the trail often stays closed until June, depending on conditions.
