Tips from the Community
Yesterday, through a highly magnified pair of binoculars on one of these islands, I was able to observe five cormorants in close harmony: Magnificent! The birdlife here is truly diverse - a magnifying glass is actually a must. But the photos stored here by Komoot users are also great in this highlight - especially the photo of the kingfisher, which I unfortunately haven't had the chance to see yet...

The Ermitage is a large and lovingly designed green area from 1785, with three idyllic ponds, several romantic grottos, historical buildings, pretty walking paths between the shore and the edge of the forest and, on top of it all, the castle ruins of Bierseck Castle, as the crowning glory of the whole. It is a wonderful place for physical and mental relaxation, but those seeking peace and quiet should visit outside of the holidays or weekends. It is a real visitor magnet. Warning! The grottos can only be reached on foot and via steep stairs. The rest of the garden is mostly wheelchair accessible and suitable for pushchairs. There are no parking spaces directly at the Ermitage! Free entry!

Beautiful bird viewing point. There are really nice photos early in the morning, as well as in the evening. But you can also see the birds really well during the day.

I've hiked around the lake several times - I'll go along the eastern shore first. The idea is simple: If my injured knee doesn't keep up after half the distance, I'll just take the train for the rest of the way, and that's only available on the west bank. (So far it has never been necessary, but who knows :-) )

The hiking trails around Lake Hallwil are simply beautiful in every season! On the left bank of the lake there are good opportunities (every 30 minutes) to take the Seetalbahn to Lucerne or Lenzburg.
