All hikers should be aware that the trails at Newell Open Space can be rugged, and we share this space with nearby cattle. We understand that hiking with cattle can make some people nervous. The University of California Agriculture and Natural Resources has some valuable information on understanding working rangelands to help improve interactions with cattle.
