The most popular route to Sandstone Peak is often a loop hike starting from Yerba Buena Road, utilizing sections of the Backbone Trail. This route is generally considered moderate. For those seeking a slightly different experience, the area offers various trails that can be combined to form longer loops, sometimes including nearby points like Tri Peaks and Inspiration Point. While the main summit trail is accessible, some sections can be steep and exposed.
While the main trail to Sandstone Peak is rated as moderate, making it accessible for many, it does involve some elevation gain and exposed sections with little shade. For beginner hikers or families with young children, it's advisable to choose shorter, more direct paths and ensure everyone is prepared with plenty of water and sun protection. There are also less strenuous trails in the broader Santa Monica Mountains National Recreation Area that might be more suitable for a very easy outing.
Parking is available at the trailhead, typically near Yerba Buena Road. However, due to the peak's popularity, the parking lot can fill up quickly, especially on weekends and during peak seasons. Hikers often recommend arriving early in the morning to secure a spot. There are no specific permits required for day hiking.
Yes, dogs are generally allowed on the trails within the Santa Monica Mountains National Recreation Area, including those leading to Sandstone Peak. They must be kept on a leash at all times. Remember to bring extra water for your canine companion, as the trails are exposed and can get very hot.
Despite its name, Sandstone Peak is not composed of sandstone. It consists primarily of igneous rock, specifically andesite breccia, formed from explosive volcanic activity millions of years ago. Hikers can observe distinctive reddish-brown rock formations along the trails, which are remnants of this ancient volcanic past. The area is also part of a rare Mediterranean ecosystem.
The round trip hike to the summit of Sandstone Peak from the trailhead parking typically takes around 1 hour 30 minutes to 2 hours for an average hiker. This can vary depending on your pace, the specific route taken, and how much time you spend enjoying the panoramic views at the top.
Given the exposed nature of the trails, it's crucial to bring plenty of water, especially during warmer months. Other essentials include sturdy hiking footwear, sun protection (hat, sunscreen, sunglasses), and layers of clothing as temperatures can change. Snacks, a map or GPS device, and a first-aid kit are also recommended.
Beyond the main summit, the trail network around Sandstone Peak offers access to other notable viewpoints such as Tri Peaks and Inspiration Point. These spots provide additional perspectives of the surrounding landscape, including the Pacific Ocean, Conejo Valley, and the Channel Islands, and can be incorporated into longer loop hikes.
The land encompassing Sandstone Peak was donated to the Boy Scouts of America in 1956 by W. Herbert Allen, who established Camp Circle X. The Boy Scouts began referring to the peak as Mount Allen in his honor, and a plaque commemorating him remains at the summit. Although a petition to formally rename it Mount Allen was denied, the name persists in local usage and on some signage.
Public transport options directly to the Sandstone Peak trailhead are very limited. The area is best accessed by private vehicle. Visitors relying on public transport would likely need to combine bus services with a taxi or rideshare for the final leg of the journey, as the trailhead is quite remote.
Sandstone Peak is part of a Mediterranean ecosystem, supporting diverse plant life. Hikers might spot canyon sunflowers, especially after wildfires, and various chaparral species. Wildlife in the area can include deer, coyotes, and a variety of birds, though sightings are not guaranteed. It's always best to observe wildlife from a distance and not disturb their natural habitat.
