Hello,

Thank you for your email.

Ropes, lines, swings or hammocks may not be fastened to any plant, fence or park structure. Attach lines to your own property only.

Thank you for your interest in California State Parks.

Best Regards,
John Garlock
California State Parks

Tried reading through all the regulations, notices and brochures but could find no reference to regulating the use of hammocks. Can you please provide any information regarding that topic?
