Sonoma Zipline Adventures operates Sonoma's only redwood canopy zipline, since 2010, on the Alliance Redwoods grove in Occidental, where ancient coast redwoods reach over 200 feet and the zipline platforms are built into living trees. The Tree Tops Tour is the standard format: seven separate zip lines (the longest 1500 feet long, top speed 40 mph), two sky bridges between trees, a spiral staircase descent inside a redwood trunk, and a final 45-foot rappel from a platform to the forest floor. The aerial route lasts about two and a half hours and covers a section of the grove no ground-level visitor sees.
Beyond the day Tree Tops Tour, Sonoma Zipline Adventures runs the Sonoma Treehouse, an overnight glamping experience in a treehouse cabin built into the redwood canopy at 200 feet up, accessed via private zipline and offered as a $550-per-person package. The treehouse sleeps two and includes the Tree Tops Tour, dinner, breakfast, and the night-time aerial silence of the redwood grove. The Eco-Certified badge is earned: the canopy infrastructure is engineered to leave no permanent trace on the host trees, and the grove ecology is explicitly part of the guide commentary on every tour. Sonoma Zipline Adventures is the most adrenaline-forward of the Sonoma County adventure operators, and the only one delivering aerial perspective inside ancient redwood canopy.
