Yosemite has a secret twin and almost nobody drives the extra mile

Hetch Hetchy’s waterfalls, domes and wildflowers

Yosemite Valley gets about four million visitors a year.

Most of them never make it to the northwest corner of the park, where another valley sits behind a granite wall and a great concrete dam.

Hetch Hetchy has the same tall cliffs, the same soaring domes, the same kind of waterfalls. What it doesn’t have is the crowds, the gift shops, or the tour buses.

Drive a little farther, and you get all of it to yourself.

The valley glaciers carved and Congress flooded

Glaciers carved this valley the same way they shaped Yosemite Valley, scraping out steep granite walls and leaving behind a flat floor. Naturalist John Muir loved it and spent years fighting to keep it wild.

He called it a temple shaped by nature itself. He lost.

Congress passed the Raker Act, and President Woodrow Wilson signed it on Dec. 19, 1913. Workers built a dam, the water rose, and the valley floor disappeared.

What you see today is a deep blue reservoir cradled by the same ancient stone Muir tried to protect.

Walk out onto the dam wall above bedrock

Your first steps into Hetch Hetchy take you across the top of the O’Shaughnessy Dam, finished in 1923 and later raised to stand about 430 feet above bedrock. It’s a flat, easy walk that takes maybe ten minutes.

On your left, the reservoir stretches back toward the cliffs. On your right, the river canyon winds away below you.

The water mirrors the clouds and the peaks on calm mornings. Even if you turned around here and drove home, you’d have seen something worth the trip.

Squeeze through a tunnel blasted straight through granite

Just past the dam, the trail enters a short tunnel cut through solid rock during the dam’s construction. The air inside is cool and the light drops away.

You come out the other side into the open valley, blinking, with the reservoir on one side and the granite cliffs rising on the other. Kids tend to stop and linger in there, running their hands along the walls.

The tunnel is short, but walking through it feels like crossing a threshold from the modern world into something much older.

Two waterfalls thunder down from 1,000 feet up

Tueeulala and Wapama Falls both drop from high cliffs across the reservoir, falling more than 1,000 feet. They’re fed by snowmelt, so spring is when they run full and loud.

Tueeulala is the thinner one, a white thread against the dark rock, and it usually dries up before summer hits. Wapama is the one you hear first, a steady roar that carries clear across the water.

By the time you see it, you’ve been listening to it for a while.

Get soaked on the footbridges below Wapama Falls

The shoreline trail runs about five miles round trip from the dam to Wapama Falls. It stays mostly flat and follows the edge of the water most of the way.

Near the falls, a set of footbridges crosses directly below the rushing water. In spring, the spray hits you before you’re halfway across.

On a warm morning, it’s not unwelcome.

The trail is one of the more rewarding short hikes in Yosemite, with the cliffs and the water and the sound of the falls building the whole way in.

Two granite giants frame the reservoir like gateposts

Look south across the water and Kolana Rock rises above the shoreline, a tall spire of granite climbing high above the surface. Look north and Hetch Hetchy Dome answers it from the other side, standing even higher.

The two formations frame the reservoir the same way the famous cliffs guard the entrance to Yosemite Valley. On still mornings, both reflect in the water below them.

You’ll find yourself stopping along the trail just to look back at them.

Push on to Rancheria Falls for the full day hike

If five miles feels short, keep going. Rancheria Falls sits about 13 miles round trip from the dam and takes most of a day.

The falls come in a series of cascades tumbling through a narrow canyon into the reservoir.

The last stretch of trail climbs above the water, and you get wide views back down the length of the valley you just walked through. Most people stop here for lunch before turning around.

It’s the kind of spot that makes you glad you didn’t quit at Wapama.

Wildflowers line the trail from early spring on

Hetch Hetchy sits lower than most of Yosemite, and that means spring gets here early. By late spring, the meadows along the shoreline trail fill with lupine, California poppy, and shooting stars.

Butterflies work the blooms on warm mornings, and birds move through the trees overhead.

The combination of granite walls, blue water, and bands of wildflowers along the path gives the valley a look all its own. Higher parts of the park are still buried in snow while this trail is already in full color.

Black bears, bats and deer share the shoreline

The valley has wildlife throughout the year. Black bears roam the backcountry, and you may come across signs of them along the trail.

Deer pass through the oak and pine shade that covers parts of the path. Birdwatchers find plenty to look for near the water.

One of North America’s largest bats, the western mastiff, lives in this corner of the park. It’s the kind of place where you keep your eyes moving, because something is usually moving along with you.

Hetch Hetchy’s trails open before the rest of the park

The low elevation gives Hetch Hetchy one of the longest hiking seasons in all of Yosemite. The trails clear in early spring while the high country is still under snow.

Fall brings golden oaks and cooler air along the water. You can often visit here when other parts of the park are completely closed to hikers.

That means more time in the season when you can actually get out and walk, and fewer people on the trail no matter when you come.

The quiet here is a different kind of Yosemite

Even on busy summer weekends, Hetch Hetchy stays calm. There are no stores, no concession stands, no shuttles pulling up to drop off tour groups.

The sound of wind and water takes over. Plenty of people who make the drive out here say it ends up being their favorite part of the park, more so than the famous valley they drove past on the way.

It doesn’t ask much of you. Just the willingness to go a little farther than most people do.

Visit Hetch Hetchy in Yosemite National Park, California

To get there, take Highway 120 to Evergreen Road, then follow Hetch Hetchy Road to the parking area above O’Shaughnessy Dam.

The entrance gate is open only during daylight hours, so check current gate times on the official Yosemite NPS site before you go. Evergreen and Hetch Hetchy Roads can close for snow from November through spring.

The standard park entrance pass runs $35 for seven consecutive days.

Bring your own water since there are no refill stations, and leave the dog at home since pets aren’t allowed on the trails.
