Redwood National and State Parks

Quick answer

Redwood National Park anchors Redwood National and State Parks in far Northern California, protecting the tallest trees on Earth, including Hyperion at about 380 feet — a location kept deliberately unpublished to protect its roots from foot traffic. Four parks, one national and three state, have been managed as a single unit since 1994 and hold UNESCO World Heritage status since 1980.

The Tree With No Address

In 2006 naturalists found a coast redwood taller than anything ever recorded and named it Hyperion — about 380 feet, taller than a 35-story building. The location has never been officially published, and that is policy, not secrecy for fun: unofficial traffic to record trees trampled the soil their shallow roots depend on, so reaching Hyperion off-trail now carries penalties. You can stand among giants honestly instead — Stout Grove in Jedediah Smith or Big Tree Wayside in Prairie Creek put old-growth trunks beside paved paths. Find any trailside trunk wider than your arm span, step back until you see its crown, then count how many people it takes to encircle it.

Four Parks, One Forest

The name on the sign is a partnership born of failure and repair. California preserved Prairie Creek, Del Norte Coast and Jedediah Smith as state parks back in the 1920s while logging continued around them; the federal park arrived in 1968, expanded in 1978, and since 1994 both agencies manage all 130,000-plus acres as a single unit. That cooperation is exactly what UNESCO cited when it listed the site as World Heritage in 1980. Notice how the highway corridor alternates between clear-cut hillsides and uncut forest — that contrast is the whole conservation story in one windshield view.

More Than Tall Trees

The parks guard about 37 miles of wild Pacific coastline, elk prairies, and salmon streams threaded through the fog belt the redwoods cannot live without. Fog is not scenery here; it is irrigation, supplying much of the water big trees take in during dry summers through their needles. Human history runs deep too — Indigenous peoples along these coasts built houses and canoes from downed redwoods long before the logging frontier arrived. Walk any grove loop at daybreak when the fog is moving through, breathe slowly, and smell how different a fog-soaked trunk smells from a sunlit one.

Frequently asked

What is the tallest tree in Redwood National Park?
Hyperion, a coast redwood discovered in 2006, measures about 380 feet tall and stands in an undisclosed location inside the park. Runners-up Helios and Icarus are also within park boundaries. Officials refuse to publish locations or trails to them because trampling compacted soil around record trees damaged their shallow root systems.
Why are there national and state redwood parks with one name?
California created three state parks in the 1920s — Prairie Creek, Del Norte Coast and Jedediah Smith — decades before Redwood National Park was established in 1968 to protect more of the remaining old growth. In 1994 the National Park Service and California State Parks agreed to manage all four together as Redwood National and State Parks.
When did the redwoods become a World Heritage Site?
The United Nations inscribed Redwood National and State Parks as a World Heritage Site in 1980, citing the coast redwood forests as irreplaceable, and added International Biosphere Reserve designation in 1983. The parks also preserve roughly 37 miles of undeveloped Pacific coastline alongside the forest.
