Michael’s Summit Trail

➤ Hike Description: Embark on a 9.2-mile journey with 2,100 feet of elevation gain, weaving through Big Basin Redwoods and Castle Rock State Parks. This moderate hike begins at the storied Skyline to the Sea Trail as it crosses Highway 236 through ancient redwood groves. We’ll transition to the Cableway Trail, entering Castle Rock’s second-growth forests, where the Gentle Giants grove stands as a testament to nature’s resilience. After crossing the murmuring San Lorenzo River, we’ll tackle the 4.9-mile Michael’s Summit Loop, navigating rustic trails with natural obstacles like fallen trees hat add a touch of adventure. At the summit, we’ll pause for lunch, where the past and present converge in a landscape reborn.

Michael’s Summit bears the name of Michael Myers, who met his end collecting abalone along California’s wild coast. His loss echoes the fall of the old-growth redwoods, once felled by logging’s relentless hand. Yet, from such endings, new life emerges. The second-growth forests of Castle Rock, preserved through the Sierra Club’s advocacy in the 1960s, rise from the ashes of clearcuts, their green spires a hymn to renewal.

The Michael’s Summit Loop, carved from this reborn land, mirrors this cycle, born from loss, it invites us to tread softly, honoring Myers’ memory and the forest’s quiet triumph. As we rest at the summit, let the whispering winds and distant ridges remind us: from every end, a new beginning grows.
