Day 5  Basel - Rigi Kaltbad

En route from Basel towards the Alps, we will visit green roofs based by natural substrates, including a 95-year old system famous for its population of rare orchids and a chicken shed with a China reed grass substrate.

The Asphof chicken shed demonstrates innovative, economic, simple success.

If blessed with clear skies, we'll take our evening aperitifs with a panorama view of the Swiss Alps (plus green roofs) from 1,500 m above sea level on Mount Rigi, "Queen of the Mountains".

The Alp Stuebli at Hotel Edelweiss in Rigi-Kaltbad has a green roof, plus a fabulous view of Lake Lucerne and the Bernese Alps (weather permitting).

The cog-wheel train station at Rigi Kulm presents a green roof at 1,800 m.
