Modellbahn
This is a model of the metre-gauge Albula railway in Graubünden, originally set up in Interlaken but dismantled in 2010 when its accommodation was lost. Most of it was recreated here in 2015.
Where Sherlock Holmes would have died if he'd ever existed, until the author decided he didn't die after all. The funicular runs in summer from Willigen (200 m south of Alpbach station) to the base of the falls. You can also walk up (say 20 min) any time free, but it's only worth coming when the falls are flowing - in winter they freeze. The upper falls are a drop of 110 m then six smaller cascades take the stream another 140 m to the valley floor. The path at the top has eroded and now stops well short of the final struggle scene.
The gorge was cut by meltwater after the last Ice Age slicing through the limestone bedrock. In 1887 a 1.4 km walkway was built through it; the cliffs are 50 m high and in places the gorge is pinched to 1 m width. Both entrances have stations on the railway to Innertkirchen, combi rail + gorge tickets available. In the first six weeks of the season only the lower west entrance is open so you have to retrace your steps - this is by Aareschlucht West station 1 km east of the village. Thereafter the upper east gate opens (marked on map) and you can walk through either way. Fridays in July and Aug the west section is lit from 18:30 to 22:00; you have to enter and exit west. The west section is also suitable for strollers and light wheelchairs. Dogs welcome on a short leash.
