At Stockhorn, a winter walk ends with fondue in an igloo. Take the cable car from Erlenbach to Chrindi, then walk towards Hinterstockensee. The approach goes up and down through the snow; grippy winter boots and warm clothes matter, including while you sit down to eat.
The igloo meals run on selected winter dates and need a reservation, including if you have a gift voucher. Confirm the return cable-car time when booking. Any skating or other activity on natural ice needs separate approval; the meal booking does not tell you whether the ice is open.
