Redwood National and State Parks: The Tallest Trees on Earth

Redwood National and State Parks protect a magnificent, fragmented ribbon of forest along the rugged coast of northern California. Together, this unique partnership between the National Park Service and the California Department of Parks and Recreation preserves nearly half of the world’s remaining old-growth coast redwoods (Sequoia sempervirens).

These ancient leviathans are the undisputed tallest living things on Earth. Soaring over 370 feet (115 meters) into the perpetual coastal fog, they are taller than the Statue of Liberty and older than many human civilizations. Walking into one of these deep, shadowed groves is a profoundly humbling, almost religious experience. The immense trunks resemble the pillars of a grand, silent cathedral, where the stillness is broken only by the melodic trill of a winter wren or the gentle rhythm of “fog drip” falling from the canopy far above.

But to think of this park solely as a collection of tall trees is to miss the ecological diversity it protects. Beyond the quiet grandeur of the redwood groves, the park boundaries encompass 40 miles of wild, driftwood-strewn Pacific coastline, vast open prairies teeming with massive Roosevelt elk, and sheer, narrow canyons draped entirely in prehistoric ferns.

Geological History: The Perfect Microclimate

The coast redwoods are true survivors, relics of a time when the Earth’s climate was far more humid. Millions of years ago, ancestors of the redwoods dominated much of the Northern Hemisphere, alongside the dinosaurs. However, as the global climate shifted, the redwoods retreated.

Today, the Sequoia sempervirens are naturally found in only one place on Earth: a narrow strip of land along the Pacific coast, stretching from central California to just over the Oregon border. The reason they thrive here—and nowhere else—is a perfect, fragile combination of geology and meteorology.

The Life-Giving Fog

The secret to the redwoods’ great height is the summer fog. The trees grow so tall that they physically cannot pump water from their roots all the way to their top branches. Instead, they rely on the dense, cooling marine layer that rolls off the cold Pacific Ocean every summer. The redwoods have specially adapted needles that literally drink the fog from the air, absorbing up to 40% of their annual moisture requirement directly through their canopy. The excess moisture condenses on the needles and drips down to water the forest floor, a phenomenon known as “fog drip.”

A Landscape Forged by Fire and Water

The geology beneath the trees is highly active, shaped by the collision of tectonic plates just offshore. The region is prone to powerful earthquakes and relentless winter storms that trigger massive landslides. Yet, the redwoods are uniquely adapted to this chaos. Their thick, fibrous, tannin-rich bark makes them incredibly resistant to both fire and insect damage. Even when massive floods bury their shallow root systems in feet of silt, a healthy redwood can simply grow a new, higher layer of roots to survive.

Wildlife & Biodiversity: From the Canopy to the Coast

Redwood National and State Parks encompass distinct ecosystems: the dense old-growth forest, the open prairies, the riparian corridors (rivers/streams), and the marine coastline. This diversity supports a staggering variety of wildlife.

The Giants of the Prairie: Roosevelt Elk

The parks are the premier destination in California to observe the Roosevelt Elk, the largest of the six recognized elk subspecies in North America. A mature bull can weigh well over 1,000 pounds and carry an impressive, sweeping rack of antlers.

• Where to find them: Large herds are frequently seen grazing in the open meadows of Elk Prairie (near the Prairie Creek Visitor Center), Bald Hills Road, and even lounging on the sands of Gold Bluffs Beach.
• The Rut: Visiting in autumn (September/October) offers the chance to witness the “rut” (mating season), where massive bulls clash antlers and let out eerie, echoing bugles to establish dominance.

The Hidden World of the Canopy

The sheer height of the redwoods creates a distinct, hidden ecosystem hundreds of feet above the ground. The massive branches of old-growth trees accumulate soil over centuries, creating “canopy soils” that support entirely different plant life, including huckleberry bushes and ferns growing high in the sky. This lofty world is crucial habitat for the endangered Marbled Murrelet, a small, fast-flying seabird that nests exclusively on the wide, mossy branches of old-growth redwoods.

The Wild Coastline

The park’s 40-mile coastal boundary is a haven for marine life. Look out to sea from the high bluffs (like Klamath River Overlook) during the migration seasons (December-January and March-April) to spot the spouts of migrating gray whales. The rugged sea stacks just offshore support noisy colonies of Steller sea lions, harbor seals, and nesting seabirds like the common murre.

At low tide, beaches like Enderts Beach reveal a colorful, miniature world in the tide pools, teeming with giant green sea anemones, vibrant ochre sea stars, and scuttling shore crabs.

Top Hikes & Must-See Attractions

Because the park is a patchwork of federal and state lands spread over 50 miles, planning your route is essential. Here are the highlights.

1. Fern Canyon (Prairie Creek Redwoods State Park)

One of the most spectacular and surreal spots in the entire park system.

• The Experience: You walk up the bed of Home Creek through a narrow, sheer-walled canyon. The vertical walls, towering 50 to 80 feet high, are completely draped in seven different species of lush, dripping, ancient ferns.
• Hollywood Fame: The canyon looks so prehistoric that Steven Spielberg chose it as a primary filming location for The Lost World: Jurassic Park.
• Logistics: The hike involves constantly wading through the creek, so wear water shoes or accept wet hiking boots. Note: Accessing the trailhead requires driving a rough dirt road with stream crossings, and a permit/reservation is required during the busy summer months.

2. Tall Trees Grove (Redwood National Park)

For many, this is the holy grail of redwood hikes. It requires effort to reach but rewards you with a profound sense of isolation among true giants.

• The Grove: Located deep in the valley of Redwood Creek, this alluvial flat contains a staggering concentration of massive trees, including the former “World’s Tallest Tree” (the Howard Libbey Tree).
• The Hike: It’s a strenuous 4-mile round trip that drops 800 feet into the canyon—which means a steep, exhausting climb back out.
• Logistics: Access is strictly limited. You must apply for a free online permit well in advance to obtain the gate code for the private logging road that leads to the trailhead.

3. Stout Memorial Grove (Jedediah Smith Redwoods State Park)

Often described as the most beautiful grove of redwoods in existence.

• The Vibe: Located on a floodplain at the confluence of the Smith River and Mill Creek, the colossal trees here are perfectly spaced, with a surprisingly clear understory carpeted in soft, green ferns. When the late afternoon sun filters through the canopy, the grove takes on a warm, glowing quality.
• Accessibility: A short, flat, 0.5-mile loop trail makes this grove accessible to almost everyone.

4. Lady Bird Johnson Grove (Redwood National Park)

Located at a higher elevation (1,200 feet), this grove frequently sits right in the thick of the coastal fog layer.

• The Hike: An easy, 1.5-mile loop trail winds through an enchanted landscape where the giant redwoods share the canopy with Douglas-fir, and the understory is choked with vibrant rhododendrons (which bloom spectacularly in late spring).

5. Newton B. Drury Scenic Parkway

If you are short on time, this 10-mile scenic drive through Prairie Creek Redwoods State Park is the best way to experience the forest from your car. It bypasses the busy Highway 101, winding slowly through the heart of the old-growth forest with numerous pull-outs and short nature trails (like the Big Tree Wayside).

Seasonal Guide: Month by Month

• Summer (June - August): The busiest season. Inland temperatures are warm, but the coastal redwood groves are heavily air-conditioned by the thick summer fog layer. Temperatures rarely exceed 65°F (18°C) in the trees. You will need layers.
• Autumn (September - November): Often the best time to visit. The summer fog begins to lift, revealing crisp, clear, sunny days. The Roosevelt elk are in the rut (mating season), making for spectacular wildlife viewing.
• Winter (December - February): The rainy season. The parks receive 60-80 inches of rain annually, mostly in winter. The rivers swell, the forest is incredibly lush and green, and you will largely have the trails to yourself. Bring excellent rain gear and waterproof boots.
• Spring (March - May): The forest awakens. Wildflowers, including the spectacular pink blooms of the Pacific rhododendrons, burst into color. The weather is unpredictable, alternating between glorious sunshine and heavy showers.

Budget & Packing Tips

• Park Fees: Navigating the fees can be confusing due to the state/federal partnership. The National Park sections are entirely free to enter. However, the State Parks (Prairie Creek, Del Norte Coast, Jedediah Smith) charge day-use fees ($8-$10) for parking at major trailheads and beaches. An “America the Beautiful” National Parks pass is honored at most, but not all, state park locations.
• Accommodation:
  • Camping: The four developed campgrounds (Jedediah Smith, Mill Creek, Elk Prairie, and Gold Bluffs Beach) are arguably the best way to experience the park. Waking up beneath the giants is unforgettable. However, they book up solid six months in advance.
  • Hotels: Base yourself in the gateway towns of Crescent City (north), Klamath (central), or Arcata/Eureka (south).
• The Essential Packing List:
  • Layers are non-negotiable: The temperature can fluctuate wildly depending on your elevation and whether you are in the fog or the sun.
  • Rain gear: A high-quality waterproof jacket is essential year-round (even in summer, to protect from the “fog drip”).
  • Waterproof hiking boots: Trails are often muddy, and hikes like Fern Canyon require walking directly in streams.
  • Binoculars: Essential for spotting whales offshore, elk in the prairies, and birds high in the canopy.

Frequently Asked Questions (FAQ)

Where is the tallest tree in the world (Hyperion)?

Hyperion (measured at 380.3 feet / 115.9 meters) is located within a remote, off-trail section of Redwood National Park. However, its exact location is a closely guarded secret. The National Park Service has completely closed the area surrounding Hyperion, and anyone caught hiking off-trail to find it faces a $5,000 fine and up to 6 months in jail. This strict measure is necessary because the heavy foot traffic of “tree hunters” was destroying the delicate understory ferns and severely compacting the soil over Hyperion’s incredibly shallow root system, threatening the life of the tree itself. There are thousands of trees over 300 feet tall on the official trails.

What is the difference between Coast Redwoods and Giant Sequoias?

While they are related, they are two distinct species.

• Coast Redwoods (Sequoia sempervirens) live only on the misty Northern California coast. They are the tallest trees on Earth, growing like massive, slender columns.
• Giant Sequoias (Sequoiadendron giganteum) live only on the western slopes of the inland Sierra Nevada mountains (like Yosemite and Sequoia National Parks). While shorter, they have vastly thicker trunks, making them the largest trees on Earth by volume.

Can I drive my car through a redwood tree?

There are no drive-through trees located within the boundaries of the National or State Parks (the Park Service’s mission is to protect the trees, not carve holes in them!). However, there are three privately owned, historic “drive-thru” trees located in towns nearby (the Klamath Tour Thru Tree, the Shrine Drive-Thru Tree in Myers Flat, and the Chandelier Tree in Leggett).

How much time do I need to see the park?

Because the park spans 50 miles of coastline, do not treat it as a quick drive-by. You need a minimum of two full days: one day to explore the northern section (Jedediah Smith and the Smith River) and one day for the southern section (Prairie Creek, Fern Canyon, and the coastline). Three to four days allows you to hike the longer trails and soak in the profound silence of the groves.
