Yosemite National Park is one of the great natural sanctuaries on the planet and, along with Yellowstone, one of the birthplaces of the very idea of a national park. In the heart of California's Sierra Nevada, it protects a landscape of granite sculpted by ancient glaciers: vertical cliffs nearly a kilometer high, domes of polished rock, waterfalls among the tallest in the world, meadows, giant sequoias and crystal-clear rivers. It is a UNESCO World Heritage Site and a magnet for hikers, climbers and nature lovers from all over the world.
The epicenter is Yosemite Valley, a flat-bottomed canyon flanked by legendary monoliths: El Capitan, the most imposing granite wall in the world and a mecca for climbing; Half Dome, the split dome that is the park's symbol; and the waterfalls of Yosemite Falls, Bridalveil and Nevada Fall. But the park is much more: the high country of Tuolumne Meadows, the panoramic overlook at Glacier Point and the giant sequoia groves of Mariposa Grove round out an overwhelming whole.
This guide covers the essentials of Yosemite with a practical eye: what to see in the valley and in the high country, how the entry system works in high season, when the waterfalls run at their fullest, where to sleep inside and outside the park, and how to get around on the internal transport. Yosemite is enormous and heavily visited, so planning ahead —especially in summer— makes the difference between a frustrating visit and an unforgettable one.
For thousands of years the valley was home to the Ahwahneechee people, of Miwok and Paiute roots, who called it Ahwahnee. The arrival of a battalion of militiamen in 1851, during the gold rush, marked the violent displacement of its inhabitants and the 'discovery' of the valley by whites. Its beauty soon attracted artists, photographers and defenders of nature. In 1864, President Lincoln signed the Yosemite Grant, which protected the valley and Mariposa Grove, a pioneering milestone in the history of conservation. The naturalist John Muir campaigned for its protection, and in 1890 Yosemite National Park was created. The full story is on our history page.

Origins, formation and what the sources say.
The name carried today by one of the most famous parks in the world was actually born of a misunderstanding: 'Yosemite' was what the neighboring peoples called —fearfully— the people who lived in the valley, not what those people called themselves. They called themselves Ahwahneechee, and they called their valley Ahwahnee. For thousands of years that granite canyon was their home. The Ahwahneechee were of Miwok roots with Paiute influence from the eastern side of the Sierra, and the name Ahwahnee is usually translated as 'place of the gaping mouth', associated with the shape of the valley. They lived from hunting, fishing in the Merced River and, above all, from gathering and processing oak acorns, the basis of their diet, and they also maintained the landscape through controlled burns that kept the meadows open.
The word 'Yosemite' actually comes from a term used by neighboring peoples to refer to the inhabitants of the valley, possibly linked to 'those who kill' or to the presence of the grizzly bear; the Ahwahneechee themselves did not use it for themselves. Anglo-American settlers took that name and applied it to the valley, fixing it for posterity. It is a typical case in which the place name that won out was born of a misunderstanding or of an outsider's perspective.
The life of the Ahwahneechee was brutally upended with the massive arrival of gold seekers in California from 1849 onward. The pressure on their lands and resources, together with the conflicts, ended in their displacement. Today their descendants keep their identity and memory alive, and the National Park Service acknowledges and shares the long Indigenous presence in the valley, a reminder that Yosemite was inhabited territory long before it was a park.
The clash between the world of the Ahwahneechee and American expansion was set off by the California gold rush. The arrival of tens of thousands of miners in the foothills of the Sierra Nevada created tensions and conflicts with the Indigenous peoples, who saw their territories invaded. To 'pacify' the region, the Mariposa Battalion was organized in 1851, a militia that pursued Indigenous groups deep into the mountains.
That is how, in March 1851, this battalion entered Yosemite Valley, in what is usually cited as the first documented entry of white men into the valley. One of its members, Dr. Lafayette Bunnell, was so struck by the grandeur of the landscape that he proposed naming it with the name he believed designated the tribe. The military operation was part of the process of displacing the Ahwahneechee from their ancestral valley.
Word of a valley of extraordinary beauty, with vertical granite walls and colossal waterfalls, spread quickly. Within a few years the first tourists, artists and entrepreneurs began to arrive. Painters of the landscape school, such as Albert Bierstadt, and pioneering photographers, such as Carleton Watkins, captured Yosemite in images that amazed the country and Europe, turning the valley into a symbol of the natural grandeur of the American West and planting the seed of its future protection.
The granite spectacle that leaves visitors breathless today took more than a hundred million years to form, and its story is told in two great chapters: fire and ice. The first began deep underground. More than 100 million years ago, during the Cretaceous period, enormous masses of magma cooled slowly several kilometers below the surface and crystallized into granite, forming gigantic plutons (batholiths). The granite of El Capitan solidified about 108 million years ago, and that of Half Dome, the youngest in the valley, about 87 million. Over tens of millions of years, erosion stripped away the rocks covering those plutons, and the uplift of the Sierra Nevada pushed them upward, until the granite stood exposed to the air.
The second chapter, the one that carved the shapes we see, was the work of ice. During the Pleistocene glaciations (roughly between 2,5 million and 12.000 years ago), enormous glaciers came down again and again through the area's old river valleys. The ice, hundreds of meters thick, acted as a colossal file: it widened and deepened the canyon, transforming its river-cut 'V' profile into the characteristic 'U' profile of a flat floor and vertical walls that Yosemite Valley has today. The glaciers polished the walls and plucked blocks from them, leaving nearly smooth faces such as that of El Capitan.
Half Dome, with its enigmatic sliced face, is the most famous example of this double action. Contrary to popular belief, it is not missing 'the other half': its rounded shape at the summit is due to a process called exfoliation (the rock peels off in curved layers, like an onion), because that summit was never covered by ice; the glaciers, on the other hand, did run along its flanks and steepen them. Understanding this story of fire and ice transforms the visit: every wall, every dome and every waterfall in Yosemite is a page in a geological account a hundred million years long.
In the twentieth century, the same granite walls that amazed the pioneers turned Yosemite into the climbing capital of the world, and into the setting for some of the most celebrated feats in mountaineering. The great wall of El Capitan, nearly 900 meters of almost vertical granite, was considered unclimbable. Until, in 1958, the climber Warren Harding, along with Wayne Merry and George Whitmore, achieved the first ascent of The Nose, the central arête of El Capitan. It took them 45 days of climbing spread over several seasons, driving pitons and fixing ropes Himalayan-style. It was a turning point: it proved that big walls could be climbed.
From then on, Yosemite was the laboratory where modern big-wall climbing was invented, with a community of bohemian climbers camping at the legendary Camp 4 (today recognized for its historic value) and pushing the limits of the possible decade after decade. The high point came in January 2015, when Tommy Caldwell and Kevin Jorgeson completed the first free ascent (free climbing, using the rope only for protection, not to make progress) of the Dawn Wall, a section of El Capitan considered the hardest big wall in the world. They climbed at night, in the middle of winter, for 19 days living hung from the wall, and their feat traveled around the globe.
This vertical epic became world famous thanks to documentaries such as 'Free Solo' (2018, Oscar winner), about Alex Honnold's ascent of El Capitan without ropes or protection, and 'The Dawn Wall'. Today, looking up from El Capitan Meadow and spotting the tiny figures of the climbers —and their lights at night— is one of the most thrilling sights in Yosemite, and living proof that the park remains the heart of world climbing.
The valley's fame and the concern for preserving it from commercial exploitation gave rise to a milestone in the history of world conservation. In 1864, in the middle of the Civil War, President Abraham Lincoln signed the Yosemite Grant, a law that ceded Yosemite Valley and the Mariposa Grove of sequoias to the state of California so that it would preserve them for 'public use, resort and recreation'. It was the first time a government protected land for its scenic value for people's enjoyment, setting a decisive precedent for the concept of a national park.
A few years later, the Scottish-American naturalist John Muir arrived in Yosemite and was captivated by its geology and its nature. Muir lived and walked tirelessly through these mountains, wrote about them in impassioned prose, developed theories about the glacial origin of the valley (correct ones, against those who attributed it to a cataclysm) and became the great apostle of its protection. His activism was key to extending conservation beyond the valley.
Thanks in large part to the campaign by John Muir and Century magazine, in 1890 the United States Congress created Yosemite National Park, which protected the high country and the forests surrounding the valley (still under state administration). In 1906, after further lobbying, the valley and Mariposa Grove were folded back into the national park under federal administration, unifying the protection. In 1916 the National Park Service was created, and it has administered Yosemite along with the rest of the country's parks ever since.
A bitter episode in that history was the construction of the Hetch Hetchy dam, in a twin valley of Yosemite's inside the park, to supply water to San Francisco. Despite fierce opposition from Muir and the conservationists, the dam was approved in 1913 and flooded that valley. The battle over Hetch Hetchy became a symbol of the environmental movement and of the limits of the national park idea.
Through the twentieth century, Yosemite established itself as one of the most visited and beloved parks in the United States, and also as the stage for the golden age of climbing on El Capitan and Half Dome. In 1984 it was declared a World Heritage Site by UNESCO in recognition of its geological and natural value. Today, with millions of visitors a year, the park's great challenge is balancing that enormous appeal with preserving the landscape, which has led to reservation and transport systems to protect a place that still leaves everyone who travels it breathless.
