This monument is famous and worth a quick visit if you are staying in Helsinki. Frankly it's a load of pipes welded together in a park. Apparently the pipes 'sing' if the wind is blowing but it was still and sunny while we were there. Great opportunity to practice your photography. Best enjoyed when there are no cruise ship groups there.
You can get there by bus (the hop-on hop-off bus stops there), tram is about 400m away through a park.
