Park Glen Canyon

Most city creeks are diverted, but Islais Creek, which formed Glen Canyon, is one of the few overland creeks where you can still see its natural flow path—and it cuts straight through the park. The impressive rock outcroppings make the park worth a visit. It’s forested by blue gum eucalyptus, so inhale deeply. It’s pretty unique to have a canyon right in middle of the city, and Glen Canyon is accessible right from its BART stop. Stay to the trails that head up high on the right side of the creek if you want to look down at the canyon.
