The steep low fell Jan-Svensamössan can be seen from far-off jutting up over the landscape. The slopes are covered with primary forest, where many endangered forest species thrive. Jan-Svensamössan is a popular spot for excursions. There are two paths up to the summit, but only one is marked – the trail leading along the southeast slope. From the top the view is certainly 100 km on a clear day, a breath-taking panorama across the Lapland forests, low fells, mires and lakes. The area is 1.2 square kilometres in size.
The nature reserve lies about 27 kilometres west of Arvidsjaur. From road 45, just over 2 km west of Avaviken, there is a road that leads to the nature reserve, signposted to Ekopark Ledfat.
