A long winding road up from Berkeley led to this Nature Area. Because the Nature Area was difficult to get to without a car, sufficient parking was provided. But note that you can get there by the AC Transit #67 bus, but the bus only runs once per hour.

A sign alongside the trail and just across from the lake read:

Please Don't Feed the Water fowl

The Park District is dedicated to protecting native wild animals. We Need Your Help. Unfortunately parks have become a favorite place to release ducks. Domestic ducks can carry diseases easily transmitted to wild ducks.

When fed regularly, the ducks quickly multiply and over populate the area. The over abundance of water fowl causes high bacterial counts that may exceed public health standards and can lead to soiled lawns and walkways.

To help us protect people and wildlife. Please Don't Feed the Waterfowl.

Wildcat Creek
(21 of 41) (4761 views)

Tilden_Park_Nature_Area_20100518_110352_4729BCX.jpg

Wildcat Creek is formed by the drainage and overflow of Jewel Lake. At one time a canal was proposed to take water from this watershed and connect it to the East Bay water supply. The canal was never completed, and Wildcat Creek is now being gradually restored to its former natural state.
