Jarník hill (609 m) is one of the highest peaks of the Písecké Hory (Písek Mountains). It lies about 3 km east of the town Písek.
On the top there is a observation tower. There are nice views of the scenery of the regions of the towns Týn nad Vltavou and Písek.
The remains of gold mining can be found on the south-western slope of the hill - the desolate former pit with remains of the adit. The former limepit with the natural rock bridge can be seen on this slope as well.
The red marked trail from Písek joins the blue one leading not far from the top (about 4 km). The way along the blue sign is possible from the villages Chřešťovice (about 10 km) and Kluky (about 5 km) as well. The red marked path continues on the slopes of the hill to the village Albrechtice nad Vltavou and to the town Týn nad Vltavou.
