• Castle hours are seasonal: Schloss Birseck opens Sunday and Wednesday afternoons from Easter to the end of October, while the garden paths stay open all year
• Riddle booklet for kids: download it free from the garden's website, or buy a printed copy for CHF 1 in Arlesheim bookshops
• Very little parking at the entrance, so the 10 tram to Arlesheim Dorf is the easier way in

Ermitage Arlesheim is a landscape garden opened in 1785 across 40 hectares of wooded valley. Paths wind past ponds, an old mill, a rock gate and a string of grottoes, up to a hermit's hut and the Schloss Birseck castle ruin with its Knight's Hall.

A riddle booklet written for kids turns the walk into a hunt for clues at each numbered station.
