We love the Santa Monica Mountains!!!
We love the Santa Monica Mountains, and that's why we are making it a priority to protect this trail, which stretches from Point Mugu State Park all the way to Will Rogers State Historic Park. The Backbone Trail is more than just a trail; it's a connection to the natural beauty, history and spirit of these mountains.
We returned to Mesa Peak Motorway to fill additional ruts and clean out more drains, helping control water runoff, prevent erosion and protect the trail from further damage. Every drain we build and every section we restore is an investment in preserving this incredible landscape for mountain bikers, hikers, runners, horseback riders and future generations. We do this because we believe in giving back to the mountains that give us so much.
This spot is my favorite along the entire 67-mile stretch. There's something truly special about its rugged rock foundation, the unique formations and the magnificent 360-degree panoramic views of Calabasas and Malibu. It's one of those places that reminds you why these mountains are worth protecting.
Siempre Adelante! One heart, one trail, one mountain strong! 💪⛰️

Keeping the Backbone Strong

The CORBA crew returned to the Encinal Canyon section of the Backbone Trail early in the morning, bringing 25 gallons of water — something Mother Nature has yet to provide.

Working together with the Santa Monica Mountains Trails Council, Larry Marino, Livia Szoke, Peter Sullivan and I spent most of the day improving this stretch of trail. Our joint effort resulted in 12 completed drains, each upgraded to today's trail standards. We widened the mouths to capture and move water off the trail more effectively and made the drains larger and stronger to help them handle winter rains and last for years to come.

Carrying 25 gallons of water into the mountains wasn't easy, but our crew believes in doing things right. Water is an important part of the process, helping the soil compact and bind together to create stronger, more durable drains.

Twelve drains might not sound like much until you stand there with a flat shovel and a pick, shaping every one by hand. Each drain takes time, muscle and patience. There's no shortcut when you're building something meant to protect the trail for years to come.

That's trail work. That's teamwork. And that's how we keep the Backbone strong.

A little history makes this stretch of trail even more meaningful. According to the Los Angeles Times, the Etz Meloy Motorway in the Santa Monica Mountains was named after early homesteaders Robert K. Etz and Horace T. Meloy. Today, this historic road is part of the Backbone Trail corridor, enjoyed by generations of hikers, equestrians and mountain bikers.

We are grateful to those who came before us and helped shape this landscape. Their legacy lives on every time someone steps onto this trail and experiences the beauty of the Santa Monica Mountains. Through partnerships between CORBA and the Santa Monica Mountains Trails Council, we continue that legacy by caring for the trail, protecting it from erosion and leaving it better for those who follow.

Siempre Adelante,
Juan Carlo

Keeping the Backbone Strong
With permission to begin drainage work on the Encinal Canyon section of the Backbone Trail, the CORBA crew arrived early in the morning to beat the heat and get to work.
Larry Marino, Livia Szoke, Denise Pomonik and I spent the day rebuilding and improving the trail’s drainage system. By the end of the day, we had completed seven drains, upgrading each one to today’s trail standards. We widened the mouths to help capture and move water off the trail more effectively and made the drains larger and stronger so they can handle the winter rains and last for years to come.
Encinal Canyon is a popular section of the Backbone Trail, used by hikers, equestrians and mountain bikers. Keeping water off the trail is one of the most important things we can do to protect the tread and prevent erosion. A well-built drain might not be the most noticeable part of a trail, but when the rain comes, it can make all the difference.
There is also something special about working on this particular section of trail. The Backbone Trail wasn't created overnight. Its development was a 25-year effort involving citizen trail-building groups, the Sierra Club, Santa Monica Mountains Trails Council, National Park Service, California State Parks and the Santa Monica Mountains Conservancy.
More than 20 years ago, people were building these sections of the Backbone by hand, creating a trail that would eventually become one of the most important routes across the Santa Monica Mountains. In 2013, the National Park Service even organized a National Trails Day project east of Encinal Canyon Road, where volunteers worked on tread, vegetation and drainage to prepare the trail to properly handle winter rain.
That's exactly what we were doing today.
When we spend an entire day moving rocks, shaping dirt and rebuilding drains, we're not simply maintaining a trail. We're continuing the work of the people who came before us.
Their tools may have been different. Their crews may have been different. But the mission is the same: build it right, take care of it and leave the trail better for the people who come after us.
Seven drains may not sound like much until you stand there and realize every rock was moved by hand and every drain was shaped with a purpose.
That's trail work.
And that's how we keep the Backbone strong.
And we're not done yet.
We'll continue the work this Saturday from 8 a.m. to 4 p.m
Siempre Adelante,
Juan Carlo

For National Public Lands Day 2026, the CORBA trail crew joined forces with the Santa Monica Mountains Trails Council and National Park Service employees to take on a trail that had been waiting for some serious love — the Hidden Valley Overlook Trail Connector.
This was one of the roughest trails in the park. Years of erosion had left huge holes and damaged sections throughout the connector, creating safety hazards for hikers. The work was needed a couple of years ago, but with limited resources and so much trail needing attention, this connector continued to deteriorate.
But that’s OK — because when there’s a tough trail project, my crew is always ready for the challenge.
We came together with one goal: bring this connector back to a safe, sustainable standard and make it enjoyable again for everyone who uses it. The trail is an important connection to the beautiful Hidden Valley Overlook, so we knew the work was worth every bit of sweat and effort.
A huge thank-you to my crew: Larry Marino, Livia Szoke, Alex Knerr, and Alex Alcantar. And thank you to Katie Preston and Nicole Kulaga, archaeologists with the National Park Service, who came out and put their hearts into the work alongside us.
The team tackled some major problems. We built a large drain to keep water from flowing onto the connector from the Hidden Valley Overlook Trail, collected and moved rocks to fill the major holes, and rebuilt sections of the trail that had been badly damaged by erosion.
It wasn’t easy. There was plenty of digging, lifting, moving rocks and working together — the kind of work that leaves you tired at the end of the day but proud of what you accomplished.
And that’s what trail work is all about.
We may start with a trail full of holes and problems, but together we leave it safer, stronger and better than we found it.
On National Public Lands Day, our crew didn’t just work on a trail. We gave a little something back to the mountains we love.
Siempre Adelante. One trail, one crew, one heart at a time.
Next week we are working at Encinal Canyon next to Mulholland- Etz-Meloy Bypass - Backbone Trail from 8 a.m-til about 2ish.

Tomorrow, Sept. 26, 2026, is the 50th Anniversary Event at Malibu Creek State Park from 4:30 to 6:30 p.m. Come join the festivities!
CORBA will be part of the celebration, and we’ll have a booth at the event.
Today, Larry Marino and I worked on the Rock Garden trail leading all the way to the MASH Site. We cleared vegetation and established sight lines so hikers, bikers and horseback riders can safely see each other while using this multi-use trail.
CORBA has been maintaining this trail for many years, and for this special occasion, we went out and did it again. We’re proud to help keep the trails safe and enjoyable for everyone.
Come join us tomorrow and celebrate 50 years of Malibu Creek State Park!

We are back working to improve the trails inside Point Mugu State Park.
We started by brushing sections of the Sin Nombre/Two Foxes Trail where we know vegetation becomes more overgrown. We also installed a drain to keep water off the trail in an area where it was beginning to form a rut.
At the same time, we have noticed illegal trail work taking place. This is a serious violation, and State Park rangers have been informed. If you see anyone doing unauthorized trail work, please report it to California State Parks at 951-443-2948.
A big thank you to our volunteers who helped Steve Messer and me with the work: Sundar Vembu and Jennifer Landa.
Thank you!
