El Cerrito Trail Trekkers invites history buffs to join a free 2.5 mile hike led by retired East Bay Regional Parks supervising naturalist Dave Zuckermann. Drink in the cool Bay breezes as you learn about the park’s storied past. This is where the transcontinental railroad once terminated — and where, in 1903, an inventor watched his ambitions to revolutionize air travel smash into a thousand irrecoverable pieces.

In Dave’s words, the hike is “an easy-paced 2.5-mile hike with a few very, very steep sections.” Meet him at the main entrance to Miller/Knox Regional Shoreline (the first parking lot to the right off Dornan Drive in Richmond).
