The gulch cut by Jack Peters Creek is bridged since 1939 by this classic Hwy 1 bridge, without shoulders, so be mindful of the fast moving traffic when trying to enjoy the excellent views to the ocean and into the densely overgrown gulch

Navarro River Redwoods State Park

Highlight • Forest

West entrance into a long, shady tunnel of magnificent second-growth redwood groves. Twisting Coastal Hwy 1, then the two-lane Highway 128 runs through the park and parallels the Navarro River’s north bank. The park’s 660 acres lie along a 14-mile contiguous river corridor. Beginning in the 1850s, heavy logging by the lumber and sawmill trade devastated the area’s old-growth redwoods. In 1987, the Save the Redwoods League purchased this fragmented riverfront acreage to link its open spaces and then donated it to the State. parks.ca.gov/?page_id=435
These second-growth redwoods—sprouted from the cut stumps of the original trees—grew rapidly in height and girth where the Navarro’s floodwaters nourished their growth.
