Unfortunately a great number of the lifts in the region operate only until 23 October. For example, you cannot visit First, Schynige Platte, Männlichen, nor Allmendhubel after that date nor take the bus to Grosse Scheidegg. You can walk from Lauterbrunnen to Stechelberg, Grütschalp to Mürren (with a stop part way along at Winteregg that has a big playground as Arno suggests), and go up the Schilthorn and Jungfraujoch. Or take a boat trip on Lake Thun (Lake Brienz ships also cease operation 23 October).
