The document summarizes a hike taken by the author on the Muir Grove Trail in Sequoia National Park. The trail started at Dorst Creek Campground and wound through a redwood forest before arriving at Muir Grove, home to hundreds of giant sequoias. Within the grove, the author observed many massive trees over 1,000 years old, some with fire-blackened trunks or unusual growth patterns. A highlight was passing through the hollowed interior of a double-trunked sequoia large enough to stand inside of.
