I was told that we could take a train from Interlaken to a town in the mountains. There we could have a picnic lunch , go for a hike and then take the funicular down the mountain and hike out of the valley. The person that told me this didn't tell me the name of the town , so I am having trouble making a plan. Could someone please help me figure this out or if you have another suggestion on something else that we could do on our special day. We are coming in by train from Basel on Sept.20th. We have a swiss pass.
