State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At 656 miles (1,056 km), it is the longest state route in California, and the second-longest in the US after Montana Highway 200. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a 54-mile (87 km) stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge.

The King Range Wilderness is a 42,585-acre (172 km2) federally designated wilderness area within the King Range National Conservation Area in northern California, United States. The area was set aside with the passage of the Northern California Coastal Wild Heritage Wilderness Act of 2006. The Bureau of Land Management is the responsible agency and is currently working on a Management Plan for the King Range Wilderness. This section of California's coastline is known as the "Lost Coast", a landscape too rugged for highway building, which forced the construction of State Highway 1 and U.S. 101 inland. The King Range Wilderness is the longest undeveloped coast, outside of Alaska, in the United States.

The Salt River is a formerly navigable hanging channel of the Eel River which flowed about 9 miles (14 km) from near Fortuna and Waddington, California, to the estuary at the Pacific Ocean, until siltation from logging and agricultural practices essentially closed the channel. It was historically an important navigation route until the early 20th century. It now intercepts and drains tributaries from the Wildcat Hills along the south side of the Eel River floodplain. Efforts to restore the river began in 1987, permits and construction began in 2012, and water first flowed in the restored channel in October 2013.
