A longer stroll down footpath from Oberer Letten, on the
north side of the Limmat, brings you to Unterer Lettern. On the way you’ll pass
some rather impressive (and neat – very Swiss) graffiti, some it on the
concrete support for the bridge in the middle of the river showing real
dedication to the craft.

Unterer Letten has an attractive wooden structure housing
showers and changing rooms, with walkways out to a sunbathing platform. Swimming
takes place in the river. Free entry.
