A great hike

What Lies Beneath: Hazel-Atlas Mine in the East Bay’s Black Diamond Mines Regional Preserve is like an Indiana Jones set. Explore the underground quarry restored to appear like its active days in the 1920s to ’40s. Don a hard hat, pick up a flashlight and join a 90-minute docent-led tour Saturdays and Sundays (through November). Don’t miss the “stopes,” where the tunnel goes from 8 feet tall to more than 30 feet tall. [Visit WeekendSherpa.com to find out more about getting outdoors in Northern California]
