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...

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.

Along the Reuss, partly in the shade of the trees, you can easily reach the Flachsee from Bremgarten.

Anyone traveling to Lake Hallwil should definitely pack their swimming trunks when the weather is nice. There are dozens of inviting and sometimes romantic places where water lovers can let off steam. The water is clear and warm! Barbecue enthusiasts will get their money's worth along the mostly wooded riverside promenade, as will nature lovers. Anyone who wants to fish can do so from the shore without hesitation. The Hallilwersee is of course also easily accessible by boat. The journey times are long and don't keep hikers/walkers waiting long. Hallwyl Castle is of course the star on the lake and certainly the number one tourist hotspot.

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 :-) )
