TILDEN
JEWEL LAKE TRAILS June 9, 2016 Home Hike Description: Tilden is a large 2000 acre park just east of Berkeley. While we have been there a number of times on various trails, this is the first time enough plants have been seen to make up a web page. I believe it's partly because the Jewel Lake area is set low between two hills and provides a respite from the desiccating sun so plants can thrive.
