45 Bike Turnouts
UPDATE: (9/14/22): We conducted a GPS Latitude/Longitude survey and confirmed 45 Bike Turnouts NOT 48 on Mount Diablo. The discrepancy between 48 and 45 is because California State Parks added asphalt to a few existing Bike Turnouts and counted them twice. South Gate Road = 17, North Gate Road = 16 and Summit Road = 12. Mount Diablo has installed 28 new and 17 old bike turnouts.
