Sequoia & Kings Canyon National Parks: The Land of Giants

Established September 25, 1890
Area 1,353 square miles

Sequoia and Kings Canyon National Parks are a land of giants. Located side-by-side in the southern Sierra Nevada mountains of California, these two parks protect a landscape of superlatives: the largest trees on Earth, the deepest canyon in the United States, and the highest peak in the contiguous 48 states. While they are technically separate parks, they are managed jointly and share a contiguous boundary, offering visitors a seamless experience of towering forests, rugged foothills, and high alpine wilderness. It is a place where you can feel small in the best possible way, humbled by the sheer scale and age of the natural world.

The Giants: Sequoia National Park

The primary reason most people visit Sequoia is to see the Giant Sequoias (Sequoiadendron giganteum). These are not just trees; they are living monuments.

General Sherman Tree

The undisputed king of the forest is the General Sherman Tree. By volume, it is the largest living single-stem tree on Earth. Standing 275 feet (83 meters) tall and over 36 feet (11 meters) in diameter at the base, it is estimated to be around 2,200 years old. Standing at its foot and looking up into its massive branches—some of which are larger than most other trees—is a profound experience.

The Giant Forest

General Sherman lives in the Giant Forest, a plateau at 6,000 feet elevation that contains five of the ten largest trees in the world. A network of paved trails, including the Congress Trail, winds through this cathedral of giants. The air here is cool and scented with pine, and the reddish-brown bark of the sequoias glows in the filtered sunlight.

Tunnel Log

A popular photo spot is the Tunnel Log, a fallen sequoia that was carved out in the 1930s to allow cars to drive through. It gives a sense of just how massive these trees really are.

The Depths: Kings Canyon National Park

North of Sequoia lies Kings Canyon, a park defined by its rugged terrain and deep valleys.

Kings Canyon Scenic Byway

The road into Kings Canyon is an engineering marvel, winding down into one of the deepest canyons in North America. At its deepest point, Kings Canyon plunges over 8,000 feet from rim to river—deeper than the Grand Canyon! The drive offers views of granite cliffs, roaring rivers, and waterfalls like Roaring River Falls and Grizzly Falls.

Grant Grove

Kings Canyon has its own grove of giants, home to the General Grant Tree. Known as “The Nation’s Christmas Tree,” it is the second-largest tree in the world and a national shrine to those who have died in war.

Zumwalt Meadow

Located deep in the canyon floor, Zumwalt Meadow is a lush oasis surrounded by towering granite walls like North Dome and Grand Sentinel. A gentle trail loops through the meadow, offering stunning views of the Kings River and the high peaks above.

Wilderness and High Sierra

While the big trees and canyons are accessible by car, over 97% of these parks is designated wilderness.

  • Mount Whitney: On the eastern border of Sequoia National Park stands Mount Whitney, the highest summit in the contiguous United States at 14,505 feet (4,421 meters). The summit can be reached via a strenuous 22-mile round-trip hike (permit required) or as the terminus of the famous John Muir Trail.
  • High Sierra Trail: For backpackers, this 72-mile trans-Sierra trek from Crescent Meadow to Mount Whitney is a bucket-list adventure, traversing some of the most spectacular mountain scenery in the world.
  • Crystal Cave: Underground, the parks are home to over 200 known caves. Crystal Cave is the only one open to the public (via guided tour), featuring beautiful formations of stalactites, stalagmites, and draperies.

Wildlife: Bears and More

The parks are home to a diverse array of wildlife.

  • Black Bears: Seeing a black bear is a highlight for many visitors. They are active year-round but most visible in spring and summer. Proper food storage (using bear lockers) is mandatory to keep them wild.
  • Mule Deer: Often seen grazing in meadows or near campgrounds.
  • Marmots: These large ground squirrels are common in rocky areas, especially at higher elevations.
  • Birds: From the tiny mountain chickadee to the soaring golden eagle, birdwatchers will find plenty to see.

Practical Information

  • Seasons:
    • Summer (July–August): All roads and facilities are open. Crowds are highest.
    • Fall (September–October): Beautiful weather, fewer crowds. Snow can start falling in October.
    • Winter (November–April): The parks are a snowy wonderland. The Generals Highway between the parks closes, but the main groves are accessible for snowshoeing and cross-country skiing. Tire chains are often required.
    • Spring (May–June): Waterfalls are at their peak, wildflowers bloom in the foothills.
  • Entrance Fee: One pass covers both parks for 7 days.
  • Shuttles: In summer, free shuttles operate in the Giant Forest area, reducing congestion.

Frequently Asked Questions (FAQ)

Can I drive through the big trees?

You can drive through the Tunnel Log in Sequoia National Park, but it is a fallen tree. There are no standing trees you can drive through in these parks (that’s the “Chandelier Tree” in the Redwoods, far to the north).

Are Sequoia and Redwoods the same?

No. Coast Redwoods (found on the CA coast) are the tallest trees on Earth. Giant Sequoias (found here in the Sierra Nevada) are the largest by volume (massive trunks). They are related but distinct species.

How far is the drive from Los Angeles/San Francisco?

It takes about 4–5 hours to drive from either city to the park entrances.

Do I need a reservation to enter?

Unlike Yosemite, Sequoia & Kings Canyon do not currently require a reservation for entry (check the NPS website for the latest updates as policies can change).

What time of year has the best wildflower display?

The foothills (below 4,000 feet) burst with wildflowers in March and April. Higher elevations around Lodgepole and the Giant Forest peak in June and July. The Mineral King valley, accessible only via a steep winding road, is especially rewarding for wildflowers in early summer.

The Science of Giant Sequoias: Why So Big?

Giant Sequoias are not just large — they are a scientific marvel, and understanding what makes them grow so massive enriches the experience of standing beneath them.

  • Fire as a friend: Sequoias have evolved a remarkable relationship with fire. Their thick, spongy bark (up to 60 cm / 2 feet deep) is nearly fireproof and contains no flammable resins. More importantly, sequoia cones can remain on the tree for 20 years, sealed shut by moisture. Heat from a forest fire dries them out and opens them, releasing thousands of seeds onto the freshly cleared, mineral-rich ash — the perfect seedbed. The National Park Service now conducts controlled (prescribed) burns to mimic this natural cycle and encourage sequoia regeneration.
  • Tannins as armor: The reddish-brown bark is rich in tannins, which repel insects and resist fungal disease. Giant Sequoias essentially never die of disease or pest infestation — the primary causes of death are toppling over due to shallow root systems and, of course, logging (now banned).
  • The age question: The oldest known Giant Sequoia is estimated at over 3,200 years old. To put that in perspective: a sequoia seedling germinated around 1200 BCE when the Trojan War was being fought, and it is still alive today.

Indigenous History: The Monache and Yokuts Peoples

Long before the parks were established, these mountains were home to indigenous peoples whose deep knowledge of the land shaped the very landscape visitors marvel at today.

  • The Monache (Western Mono): The Monache people inhabited the western slopes of the Sierra Nevada for thousands of years, using the Giant Forest and surrounding meadows as summer hunting and gathering grounds. They burned the forest understory intentionally and regularly — a practice that, unknowingly, was also key to sequoia regeneration.
  • Acorn as staple: Black oak acorns were a cornerstone of the diet. The large, open black oak woodlands found in parts of the parks today are partly a legacy of generations of deliberate tending by indigenous communities.
  • Collaboration today: The National Park Service works with the Wuksachi and neighboring tribal nations to incorporate traditional ecological knowledge into modern land management, including the renewed use of cultural burns — a full-circle acknowledgment that indigenous stewardship preceded and, in many ways, shaped modern conservation.
