What are the best hikes in San Francisco and the Bay Area? Chronicle data editor Dan Kopf joins Total SF hosts Peter Hartlaub and Heather Knight to talk about their recent collaboration, using more than 600,000 AllTrails user reviews to determine the best and worst hikes in the region. Kopf talks about his own love of hiking (and fungi) and the 10 best local trails, Knight recounts her journey on the worst trail in S.F. and Hartlaub explains whether the highly-rated Dipsea Trail cured his dislike for hiking. Produced by Peter Hartlaub. Music from the Sunset Shipwrecks off their album "Community," Castro Theatre organist David Hegarty and cable car bell-ringing by 8-time champion Byron Cobb. Follow Total SF adventures at www.sfchronicle.com/totalsf  Learn more about your ad choices.
