Yosemite Valley: John Muir's Cathedral of Stone and Light
John Muir called Yosemite Valley 'the grandest of all the special temples of Nature' — and standing beneath El Capitan's 900-metre granite face, it is impossible to disagree with him.
Yosemite Valley is a glacially carved valley in the Sierra Nevada mountains of California, seven miles long and one mile wide, enclosed by granite walls that rise up to 900 metres from the valley floor. The valley was carved by glaciers over the past million years, and the flat valley floor — once the bed of a glacial lake — is surrounded by some of the most dramatic rock formations in the world: El Capitan, the largest exposed granite monolith on Earth; Half Dome, the iconic rounded peak that has become the symbol of Yosemite; and the Cathedral Rocks and Spires, which inspired John Muir's description of the valley as a temple.
El Capitan — 'The Captain' — rises 900 metres from the valley floor in a single vertical face of granite that is the ultimate challenge for rock climbers. The first ascent of El Capitan was made in 1958 by Warren Harding and his team, who spent 47 days on the wall. Today, the most skilled climbers can ascend the Nose route — the classic line up the centre of the face — in under two hours. Alex Honnold's free solo ascent of El Capitan in 2017 — climbing the 900-metre face without ropes or protection — is widely regarded as the greatest athletic achievement in the history of climbing.
The waterfalls of Yosemite are among the finest in North America, fed by the snowmelt from the Sierra Nevada that peaks in May and June. Yosemite Falls, the highest waterfall in North America at 739 metres, drops in three stages from the valley rim to the valley floor and can be heard from kilometres away during the peak flow. Bridalveil Fall, at the western end of the valley, is the first waterfall most visitors see as they enter through the Wawona Tunnel, and its delicate, wind-blown appearance — the name comes from the way the water is blown sideways in a breeze — makes it one of the most photographed in the park.
Half Dome, the rounded granite peak that rises 1,444 metres above the valley floor at the eastern end of the valley, is the most iconic feature of Yosemite and the destination of the park's most popular hike. The Half Dome Trail covers 14 miles round trip with an elevation gain of 1,500 metres, and the final 120 metres to the summit are climbed using steel cables fixed to the rock face. The hike requires a permit, which is allocated by lottery, and the view from the summit — over the valley, the High Sierra, and the Central Valley of California — is one of the finest in the American West.
The Mariposa Grove, at the southern end of Yosemite National Park, contains over 500 giant sequoias — the largest trees by volume on Earth. The Grizzly Giant, estimated to be between 1,800 and 2,700 years old, has a base circumference of 29 metres and is the oldest known giant sequoia in Yosemite. The grove was one of the first areas in the United States to be protected for its natural beauty — Abraham Lincoln signed the Yosemite Grant in 1864, protecting the valley and the Mariposa Grove from private development, in what is considered the first act of government conservation in American history.
Yosemite National Park receives around four million visitors a year, and the valley — which covers only one percent of the park's area — bears the brunt of this pressure. The National Park Service has implemented a reservation system for vehicles entering the valley during the peak season, and the shuttle bus system that connects the main attractions within the valley is the recommended way to get around. The best way to experience Yosemite away from the crowds is to explore the high country — the Tuolumne Meadows area, at 2,600 metres above sea level, offers spectacular hiking and far fewer visitors than the valley.
The best time to visit Yosemite depends on what you want to see. Spring (April-June) offers the highest waterfalls, the greenest meadows, and the most dramatic light — but also the largest crowds and the highest accommodation prices. Summer (July-August) is the peak season, with warm temperatures and all facilities open, but the valley can feel overwhelmingly crowded. Autumn (September-October) offers smaller crowds, golden foliage, and comfortable temperatures. Winter (November-March) brings snow to the valley, transforming it into a landscape of extraordinary beauty, and the crowds are at their smallest — but some roads and facilities are closed.
