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.

The Old Haul Service Road is described as one of the most scenic beginner rides in the Bay Area, offering a 10-mile round trip accessible near the Iverson Cabin site. This route provides a relatively gentle introduction to gravel biking amidst the redwoods. For a moderate option, consider the White Oak Trail – Bella Vista Trail loop from Los Trancos Open Space Preserve, which is just under 10 km with moderate elevation.

Keep an eye out for diverse wildlife such as banana slugs and black-tailed deer. Notable highlights include the Sequoia Nature Trail and the Eugene and Bolton Memorial Grove.
