Questions about VIOLIN LAKE

I have a few questions about Violin Lake. When I was a child I remember family members saying they had hiked to Violin Lake and recently my interest in this hike was sparked again. After doing a quick google search I found that the area is now off limits and is city (private) property. I was really interested in taking a hike out there (no fire, no camping, just a hike and snap a few photos) but now I'm not sure what the repercussions of that would be. Does anyone know if this is still a banned activity? Also, why would there be bans on going to the middle of the forest? It seems very strange to me that the government would ban hiking activities near a lake in the middle of nowhere. Thanks in advance.
