The imposing mountain backdrop at Lake Oeschinen attracts hundreds of fishermen – young and old.
Swiss Public Television, SRF, met mountain guide Fritz Loretan, who works for the commune of Kandersteg and makes sure the ice is at least 10cm thick and therefore safe for people to fish.
This is home to rainbow trout, Canadian trout and char, but if they're not 25cm long, the fishermen have to throw them back in. You need a license to fish and on peak days, 150 to 200 are sold.
Thanks to pictures being shared on social media, ice fishing from the lake is becoming more popular.
