Beat the summer heat and give a salutation to the rising sun on this early morning outing on Mangini Ranch. Save Mount Diablo’s 208-acre property includes the headwaters of Galindo Creek with rolling grasslands, oaks, buckeyes, and a rare desert olive grove. Visit a secret spring and keep your eyes out for bobcats and coyotes looking for breakfast, plus burrowing owls, quail, and many other feathered friends who are active in the morning. This is a two hour, four-mile hike with one strenuous climb. Be sure to dress in layers and wear sturdy boots or shoes; bring plenty of water, sunscreen, and a snack.
