Höllensteinlucke – the breather for altitude heroes 😅 Are you on your way to the Höllensteinhaus, panting like a broken vacuum cleaner and wondering if you're lost? Don't worry – you've arrived at the Höllensteinlucke! 🎉 This legendary "lucke" isn't a magical portal, but simply a small cut in the terrain – but for tired hiking legs, it feels like a gift from the Vienna Woods. 🌲✨ Here you can take a short breather, question your existence, and mentally prepare for the final climb. Because from here on, things get tough again – but hey, you're not here for fun. Or are you? 😄

The Antonsgrotte opposite the Cholera Chapel in Helenental is a popular destination. The place of worship, always decorated with candles, now has another attraction. Bird feeding is carried out there with particular passion, and indeed: the birds eat a lot and happily. BADEN. Bird feeding at the Antonsgrotte is a tradition. Elisabeth Werkmann - she has been looking after the Antonsgrotte for five years - took over this task last year from her predecessor, who suddenly dropped out.

The network of promenades dates back to Archduke Anton (1779–1835), who had it built in the years up to 1829. The highlight was the Antonsgrotte, which stands roughly opposite the Cholera Chapel, which did not yet exist at the time. The approximately 2.2 km long section of the Helenental from Antonsbrücke to Antonsgrotte is therefore called Antonstal. Source: https://de.m.wikipedia.org/wiki/Helenental
