Giant Forest Sequoias
📍 California, USA
Groves of giant sequoias — the largest living things on Earth by volume — including General Sherman, a single tree containing more wood than almost any other organism alive.
What makes it marvelous
The giant sequoia is not the tallest tree (the coast redwood claims that) nor the oldest, but by sheer bulk it is the largest living thing on the planet. In the Giant Forest of California's Sierra Nevada stands General Sherman: roughly 84 metres tall with a trunk over 11 metres across at the base, containing more wood volume than virtually any other single organism alive, and estimated at over two thousand years old. These trees grow only in scattered groves on the western slope of the Sierra, at elevations where winter snowpack feeds them through dry summers. Their thick, spongy bark resists fire — indeed they depend on it, since the heat opens their cones and clears competing undergrowth. Standing among their vast cinnamon-red trunks, it is nearly impossible to hold their scale in your mind.
Why visit
Walking among trees so massive they defy the eye — and standing at the base of the largest living thing on Earth — is a genuinely staggering experience, and the groves are easily reached on gentle forest trails.
What to know before you go
🗓️ Best time
Late spring through autumn (roughly May–October) for open roads and clear trails; winter brings deep snow, when snowshoeing among the giants is magical but access is limited.
🧭 Getting there & access
In Sequoia and Kings Canyon National Parks on the western Sierra Nevada, reached by road from California's Central Valley; the Giant Forest and General Sherman are served by short, mostly flat paved trails.
Good to know
- Walk the Congress Trail from General Sherman for the finest groves.
- Come early or late in the day for quieter trails and better light.
- Stay on paths — sequoia roots are shallow and easily damaged by trampling.
Plan your visit
Easy🧭 Getting there
From Visalia or Fresno, California
- Fly → Fresno (FAT) or drive from Los Angeles — roughly 4h — or the Bay Area — roughly 4h30–5h
- Drive Visalia → Ash Mountain entrance on Highway 198 — about 1h
- Drive the Generals Highway → Giant Forest — a further 45 minutes to an hour of steep switchbacks
- Total travel
- Around two hours from Visalia to the big trees
- Time at site
- A full day for Giant Forest; two if you add Kings Canyon
- Access
- National park entry fee, valid for a week and covering both Sequoia and Kings Canyon. The practical constraints are the road and the season: the Highway 198 approach has a vehicle length restriction on the switchbacks that turns back longer RVs and trailers, and the Generals Highway requires tyre chains in winter and closes in storms. Wildfire has closed sections of this park in recent years and giant sequoia groves have burned. Check current road, fire and chain status with the National Park Service on the day you travel.
🎒 What to bring & consider
- A vehicle within the length limit for the Highway 198 switchbacks, or the Highway 180 approach through Kings Canyon instead — this catches out people in rented RVs every season
- Tyre chains carried in your car from roughly November through April, whether or not there is snow at the entrance, because the road climbs several thousand feet
- Warm layers: Giant Forest sits around 2,000m and is far colder than the Central Valley you drove up from
- A bear-aware routine — food out of the car and into the provided lockers, which rangers enforce
- Patience for parking, since the General Sherman lot fills early and the summer shuttle is often the faster option
👁️ What to expect
- Crowds
- The General Sherman boardwalk is genuinely crowded in summer. Walk fifteen minutes into the Congress Trail and it empties out.
- Conditions
- Gentle paved and dirt trails at altitude. Snow on the ground well into spring. Summer afternoons can be smoky when fires burn in the range.
- Facilities
- Museum, shuttle, lodging at Wuksachi, food service and campgrounds. Fuel is limited inside the park.
- The view
- Sequoias defeat cameras — nothing conveys the base of General Sherman without a person in frame for scale. The more rewarding picture is fog or low sun between trunks on the Congress Trail, early, before the crowds and while the light is still raking.
Times and requirements are approximate and change with season, weather, and local rules — confirm permits, fares, and schedules with operators before you travel.
Natural riches of the area
- The largest living organisms on Earth by volume
- General Sherman: ~84 m tall, 11 m trunk, 2,000+ years old
- Fire-adapted bark and cones that need heat to open
- Sierra Nevada montane forest fed by winter snowpack
Local food
- Central Valley produce
- California's orchards and farms supply fruit and vegetables year-round.
- Sierra trout
- Trout from the mountain streams and lakes of the range.
- Farm-to-table California cooking
- Local, seasonal cuisine in the gateway towns.
The giant sequoia is neither the tallest tree on Earth nor the oldest — but by sheer bulk, nothing alive comes close. In the Giant Forest of California’s Sierra Nevada stands General Sherman, roughly 84 metres tall with a trunk over eleven metres across at its base, holding more wood than virtually any other single organism on the planet, and reckoned to be more than two thousand years old.
These giants grow only in scattered groves on the western slope of the Sierra, where winter snowpack carries them through the dry summers. Their thick, spongy, cinnamon-red bark shrugs off fire — in fact they need it, since the heat opens their cones and clears the competing undergrowth their seedlings can’t survive. Walking among them on the easy forest paths, it is nearly impossible to hold their scale in your head: the eye simply refuses to accept how large a living thing can be.
