Sequoia and Kings Canyon National Parks are managed together, sit side by side, and offer two dramatically different Sierra Nevada experiences. Sequoia is home to the largest tree on Earth and one of the park system’s most memorable stair climbs. Kings Canyon has another grove of giants, a deep glacial canyon, roaring rivers, and one of California’s most spectacular scenic drives.

Can you visit both national parks in one day? Yes, but plan on an early start, a late finish, and plenty of time behind the wheel. I entered Sequoia National Park shortly before 7 a.m. and spent the day hiking among giant trees, climbing Moro Rock, chasing waterfalls, and driving to the end of the road in Kings Canyon.

Here’s how I did two national parks in one day.

Start Early at Sequoia National Park

I left Sequoia Village in Three Rivers at 6:30 a.m. A gaggle of wild turkeys crossed my path as I drove toward the Ash Mountain Entrance, where I stopped for the classic park-sign picture.

The rustic wooden sign has welcomed visitors since 1935. Its carving was inspired by the Native American profile on the Buffalo nickel and intended to honor Sequoyah, the Cherokee scholar who created a written system for the Cherokee language.

Getting into the park early gave me a jump on the crowds and allowed me to drive to Moro Rock before summer shuttle started running for the day.

Stop at Tunnel Rock and Hospital Rock

Just beyond the entrance, Tunnel Rock is an easy first stop. The road once passed underneath the massive granite boulder, but vehicles are no longer allowed through it. I had the landmark to myself for a few minutes during short stop.

About three miles farther along Generals Highway, make a 15-minute stop at Hospital Rock to see Native American pictographs. The parking and picnic area are on one side of the road, while the pictographs are across the highway and up a very short set of steep stairs.

It was magical having the ancient art to myself as the sun shined through the trees. This area was once home to hundreds of Mono, Yokuts, and Tübatulabal people. Don’t miss the community kitchen near the pictographs. The small depressions in the bedrock were mortars used to grind acorns into flour.

Climb Moro Rock Before the Crowds Arrive

The drive toward Giant Forest is narrow, steep, and extremely winding. As the road climbs above 5,000 feet, the landscape quickly changes. Suddenly, you’re surrounded by towering trees.

Moro Rock was one of my favorite stops of the day. I arrived at the parking area shortly after 8 a.m. and climbed more than 350 steps to the top of the granite dome.

The elevation gain is only about 180 feet, but the staircase is steep and exposed in places. The reward is a panoramic view of the Great Western Divide and the deep river drainages carving through the Sierra Nevada.

It took me a little over 16 minutes to reach the top, even with stops for pictures and videos. I made it down in about seven minutes and briefly had the summit to myself before more hikers began climbing.

The temperature was a comfortable 60 degrees. Later in the day, it would be more than 30 degrees warmer on the floor of Kings Canyon.

Summer access to Moro Rock varies. On weekends and holidays, the road may close to private vehicles when shuttles are operating. Check the current road and shuttle information before your visit.

See the General Sherman Tree

My next major stop was the General Sherman Tree, the largest tree on Earth by volume. It stands nearly 275 feet tall and is estimated to be about 2,200 years old. Its trunk contains enough wood to build approximately 120 average-size houses.

The main trail begins near Wolverton Road and descends about half a mile through Giant Forest. Stop at the overlook for your first full view of General Sherman before continuing down to the tree.

Remember that what goes down must come back up. The parking lot is around 7,000 feet above sea level, and the trail drops more than 200 feet. Don’t be surprised if the return climb leaves you a little breathless.

Hike the Congress Trail

After seeing General Sherman, I continued onto the Congress Trail. This paved, roughly three-mile route is one of the best ways to spend more time among the giant sequoias.

A trail detour took me past the Tough Twins, two enormous trees scarred by wildfire. Burn marks are visible on many trees throughout the grove, yet giant sequoias have evolved to survive fire. Their thick bark offers protection, and fire helps release seeds and clear the forest floor.

The trail can get a little confusing near the McKinley Tree junction. Watch the signs closely, especially where the Alta and Congress trails connect.

I spent about an hour and 45 minutes seeing General Sherman, hiking the Congress Trail, and simply enjoying the forest. It is hard to rush when you’re walking among trees that have stood for thousands of years.

Drive from Sequoia to Kings Canyon

I left Sequoia National Park shortly before noon. Generals Highway passes through sections of Giant Sequoia National Monument and Sequoia National Forest before reaching Kings Canyon National Park.

It is a beautiful drive, but the winding mountain roads make travel times longer than the mileage suggests. This isn’t a day for a rigid schedule or a lead foot.

Walk the General Grant Tree Trail

My first major stop in Kings Canyon National Park was Grant Grove. The easy, paved General Grant Tree Trail is only about one-third of a mile, but it packs in several noteworthy sights.

General Grant is one of the largest trees in the world. It stands about 268 feet tall, measures roughly 40 feet across at ground level, and has an estimated age of 1,700 years.

Walk behind it to see the massive fire scar. Then continue around the loop to the Gamlin Cabin, Centennial Stump, and Fallen Monarch. You can walk through the hollow trunk of the Fallen Monarch, which has served as everything from shelter to a stable over the years.

The Centennial Stump offers a far less cheerful chapter of sequoia history. The tree was cut down in 1875, and a section of its trunk was shipped to the 1876 Centennial Exhibition in Philadelphia. Some attendees refused to believe it came from a single tree and called it a “California hoax.”

I left the General Grant Tree area around 1:15 p.m. for the long drive into Kings Canyon.

Drive the Kings Canyon Scenic Byway

If you have the time and the road is open, continue from Grant Grove toward Cedar Grove on the Kings Canyon Scenic Byway. The 32-mile drive passes through national forest and national park land before descending to the canyon floor.

The farther I drove, the thinner the crowds became. Mountain overlooks gave way to canyon walls, and the road eventually began following the cold, swift Kings River.

Grizzly Falls is a worthwhile quick stop along the drive. The 80-foot waterfall is only about a tenth of a mile from the shaded picnic area. It is technically in Sequoia National Forest, but it is one of the easiest and prettiest stops along the byway.

I also stopped at Cedar Grove, Roaring River, and Knapp’s Cabin. The small cabin sits just off the road. I walked through its front door and out the back, where the view opened to a meadow, the river, and towering canyon walls.

At the end of the road, I was six miles beyond Cedar Grove and 37 miles from Grant Grove. It was 89 degrees when I began driving out at 3:10 p.m., quite a change from the 60-degree morning at Moro Rock.

Make time for Junction View on the return drive. The overlook faces the meeting point of the Middle and South forks of the Kings River, with Junction Ridge rising above them. It was one of the most impressive views of my day.

As I enjoyed the scenic drive back out of the canyon, I found myself dreaming of a return visit for a multi-day backpacking adventure deep into King Canyons.

Can You Really See Both Parks in One Day?

Yes, especially during summer or early fall when the road to Cedar Grove is open. But this is a highlights tour, not an in-depth visit.

My day included:

• Tunnel Rock
• Hospital Rock
• Moro Rock
• General Sherman Tree
• Congress Trail
• General Grant Tree
• Kings Canyon Scenic Byway
• Grizzly Falls
• Cedar Grove
• Roaring River
• Knapp’s Cabin
• Junction View

I entered Sequoia shortly before 7 a.m. and left the end of the road in Kings Canyon shortly after 3 p.m. I continued to Lake Isabella and arrived around 8:30 p.m., making it a very long but rewarding travel day.

Tips for Visiting Sequoia and Kings Canyon in One Day

Start by 7 a.m. or earlier. Parking near General Sherman and Giant Forest often fills by midmorning.

Hike Moro Rock early to beat the heat, crowds, and summer vehicle restrictions.

Bring food and water. Services are limited, especially along the Kings Canyon Scenic Byway. Pack a picnic lunch. You’ll want more than just snacks.

Fill your gas tank before entering. Distances are deceptive, and there are no quick shortcuts across these mountains. There’s no gas stations in the parks and limited options in National Forest land.

Download maps before your trip. Cell service is spotty or nonexistent in much of the parks.

Prepare for temperature swings. I went from 60 degrees at Moro Rock to the low 90s in Kings Canyon.

Check road conditions. Cedar Grove and portions of the route between the parks are seasonal and can close because of snow, rockslides, or other hazards. Review the latest National Park Service conditions before leaving.

Have a backup plan. If the Cedar Grove road is closed or you want a shorter day, spend more time in Grant Grove or add the Big Trees Trail near Giant Forest Museum.

Two Parks, Two Very Different Experiences

Sequoia and Kings Canyon National Parks may share a boundary and one park administration, but they don’t feel like the same park. Sequoia wowed me with its colossal trees and the lofty view from Moro Rock. Kings Canyon surprised me with its uncrowded scenic drive, rushing river, waterfalls, and sheer canyon walls.

Visiting both in one day requires an early alarm for a long day. It also delivers one extraordinary day in the Sierra Nevada.
