The water from Lake Yngern is very clean and some people drink it, but Sörmlandsleden leaves no guarantee.
Parking along the section 13:2: Center of Nykvarn, Jägarskogen nature reserve, Sandtorpsbadet.
This section starts at Nykvarn train station and follows Holländarvägen Street, up to the paths through the old-growth forest down to Lake Yngern and the nice beach at Sandtorpsbadet (after around 6 km).
The trail continues southwards over Vargberget (Wolf Hill) with beautiful views all the way down to Nykvarn. Thereafter a few kilometres along a tarmac road, until you reach the beautiful Sjöslingan round trail along the shores of Lake Yngern, to the bridgeway between Lake Yngern and Lake Gullsmorasjön. You´ll find a nice rest area there. Now you´re in Gnesta County, on your way past a natural spring and to the end of this section near Lake Djupsjön. Sections 13:1 and 13:2 connect to the main trail there (section 13).
