The path up to the ruins is steep but ok, however the way back down again (on the side of the island nearest the bridge) was very difficult. It was not an “easy” path at all. We needed to hold on to tree roots where the path had disintegrated to stop us from sliding down to the bottom as there were a lot of loose rocks and gravel.

The lake is a real insider tip and, as far as I know, privately owned, but open to everyone. The idyllic setting is unfortunately somewhat marred by the nearby Fernpass road and traffic noise, but it's still worth seeing. A very beautiful lake with clear water, perfect for a leisurely stroll around it. The Sigmundsburg Castle ruins on the peninsula in the middle of the lake should be enjoyed with caution; you have to be aware of constant rockfall here. Unfortunately, it's slowly crumbling away...

The ruins of the former Sigmundsburg Castle stand on a wooded island in Lake Fernstein. Only the remains of the ruins remain. It is one of the seven castles built in Tyrol by Archduke Sigmund the Rich. The ruins (sometimes called Sigmundsberg) – completely hidden by forest – are barely visible from the shore.

We also drove up the pass with luggage. The path was quite difficult to navigate due to the loose gravel. Especially since most of the people were coming towards us, it was very narrow. Definitely not for beginners.
