Some say you haven't truly experienced Skaftafell until you've conquered the twin peaks of Kristínartindar. Standing at 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 11 miles) from the visitor center. Access is closed usually starting from mid-September and over the winter because of snow, ice, and windy weather. Due to meltwater in the spring, the path stays closed until around May or early June, depending on conditions.
