Redwood trees are some of the tallest and oldest living organisms on Earth. Towering up to 350 feet, these majestic trees can live for over 2,000 years. Found primarily along the coast of Northern California, redwoods thrive in the cool, foggy climate. Their thick, reddish bark provides protection from fire and insects, making them incredibly resilient. Walking among these giants is a humbling experience, with their sheer size and age creating an awe-inspiring atmosphere.

This peak is the highest point of Butano State Park, sharing its name with the park itself. If you're cycling on Butano Fire Road, you'll pass by it. As an interesting fact, the name "butano" originates from how early Californians referred to a beverage made from the horn of a bull or another animal, although other sources suggest it may also have a Native American origin.

It's important to note that while the San Lorenzo Valley Water District (SLVWD) manages specific trails, bikes are generally not permitted on these particular SLVWD-managed properties.

The gravel bike routes available in the San Lorenzo Valley tend to be on the more challenging side.
