We meet at the train station in Lauterbrunnen at 14:00 and walk 45 minutes along the valley to an impressive underground waterfall. On the way you may see base jumpers landing in the valley. We can later meet for refreshments before returning to Lauterbrunnen. Perhaps there will be an alternative BBQ at 17:00, but it's not yet fixed. See later the comments on this page.
When you register by e-mail, say whether you need a lift by car from the Bene train station. The event will be cancelled in case of bad weather. Check also this page.
