Even the longest is under 3/4 of a mile. But really worth the walk to see the sculptures
Around a half mile maybe.
Several dirt/gravel trails. Length(s): maybe a mile total...? The sculptures are connected by at least a mile of sidewalks.
Measuring in time, one path takes like 20-30 minutes and the other takes like 45-60 minutes.
Some are shorter, like a mile, but I would say at least a mile and a half. Their website actually gives this information.
