Friends of Five Creeks and Transition Albany invite you to enjoy Cerrito Creek and Albany Hill on a spring evening, celebrating the 40th anniversary of Earth Day. Meet at 6 PM at Peet’s Coffee, San Pablo and Carlson, El Cerrito; wear long pants and sleeves (poison oak) and sturdy hiking shoes with good traction; bring sticks if you use them. This two-hour exploration of rare urban wilderness with fascinating history will cross the creek on stepping stones and gain 300′ elevation on moderately steep, narrow dirty trails — with refreshments at the top!
