Ruins are always worth a visit! It's on the path, so it's not a special detour. The ruins are not particularly large. At the top there is a small viewing area with a bench. Beautiful view of the Danube included.

A pure nature experience in the Donau Auen National Park. First we went along the Danube and then up the Braunsberg, with wonderful views of Hainburg, the Danube and Slovakia. Away from the hiking trails, a sea of spring flowers embedded in beautiful green 🌸🪻🌼 ☀️

May 10, 2025,Hainburger Au – Ruine Röthelstein - Blick nach Devin - Braunsberg

Caution: On the way back, after the Maria-Lourdes devotion, there's a shortcut towards Braunsberg, where you have to bend down to avoid low-hanging branches. If you stand up too early, you might be struck in the face by a dangerous (partially broken or cut) branch, which can be very dangerous for your eyes!

The Danube floodplains on the Austrian side are always worth a visit, especially if you are looking for pure nature …
