The ideal starting and ending point for circumnavigating the lake. Large parking lot available, including a swimming pool if you feel like it.

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.
