Mariposa Grove Loop

The full Mariposa Grove Loop takes you on a winding tour through one of the world's most impressive stands of giant sequoias — trees so massive they make old-growth redwoods look like saplings. The trail starts with a gentle climb through mixed conifer forest before the first giants appear, and from there it's one jaw-dropping tree after another. You'll pass the Grizzly Giant (estimated at 1,800 years old, with a lower branch thicker than most tree trunks), the California Tunnel Tree, and the Fallen Monarch. The elevation gain is spread evenly across the loop, more of a steady leg-warmer than a grind. The upper grove thins out the crowds and rewards you with the biggest trees and the deepest quiet. This is ideal for hikers who want a real walk — not just a boardwalk selfie stop — but don't need to suffer for the scenery.
