Temporary Trail Closures In Cheeseboro and Palo Comado Canyons in April and May

Tuesday, April 2nd, 2013

THOUSAND OAKS, Calif. – The National Park Service (NPS) is advising visitors that trails at Cheeseboro and Palo Comado Canyons will be intermittently closed during April and May due to the demolition and removal of surplus water conveyance infrastructure.

Several days of trail closures are expected, though limited to weekdays between 8:00 a.m. and 5:00 p.m. Visitors can find up-to-date information on trailhead signs, by calling 818-889-8996 or by visiting

Triunfo Sanitation District (TSD) will be removing the Palo Comado Pump Station and the Cheeseboro Reservoir. These facilities, owned by TSD, were built in 1959 at the behest of comedian Bob Hope, who had hoped to build thousands of homes in the surrounding area as part of a master-planned community. TSD is decommissioning the facilities as part of an agreement with the NPS and other agencies.

Large trucks will be hauling salvaged materials along both the Palo Comado and Cheeseboro Canyon trails to recycling centers. For their safety, visitors are asked to refrain from using these trails when posted as closed.

Entrance to trails from Cheeseboro Canyon, Doubletree and Smoketree trailheads will be periodically closed. The China Flat trailhead and trailheads for Upper Las Virgenes Canyon Open Space Preserve will remain open.

The NPS and TSD appreciate the public’s cooperation with this effort. Additional information is available by calling 818-889-8996.

February CORBA Kids Ride – Cheeseboro Canyon

Monday, February 25th, 2013

On February 2nd, four kids and and four adults rode Cheeseboro Canyon through Sulpher Springs and to the first big wall. New riders Josh and son, Zachary joined us again, and Joy and RJ came back after several months.  Larry hiked along side son, Elliot who was determined to ride on training wheels, and he did!

It was a perfect day; the weather warmed up gradually, and the kids had lots of opportunities to practice trail ettiquette as the canyon was very busy with runners training for the upcoming marathon in March.

Next ride March 2 at 9 a.m. Sullivan Canyon, Brentwood side.  Hope to see you and your kids there!

Resolve to Solve in 2013

Monday, December 10th, 2012

How many of you have New Year’s Resolutions that you are hoping to keep? There is one you can make and keep, guaranteed. It will help you, the mountain bike community, and the trail community at large. Ready? Slow down when passing others!

How many things in life can you do that actually solve a problem? On our trails, the one justifiable complaint about mountain bikers is that they sometimes go too fast when passing others, which can be scary and upsetting,even to other cyclists. So all you have to do is slow down when passing, and you SOLVE THE PROBLEM!

Slowing down while passing others on our shared-use trails is a pure win-win proposition. The people who you pass feel good about mountain bikers. WIN! You feel good because you didn’t scare anyone, and everyone has a pleasant exchange. WIN!

Here’s a suggestion: Treat others you are passing on the trail as if you are holding the door open for them. That brief pause is a show of consideration, courtesy, and humanity that will come back to you and the mountain bike community in many positive ways.

It’s up to you. Would you rather finish your ride knowing you did something positive for mountain bikers and trails users, or that you made it worse for yourself and the mountain bike community? You CAN make a difference. And all it takes is slowing down when passing other users!


It’s not Strava’s Fault Mountain Bikers are Ignorant

Monday, September 3rd, 2012

By Mark Langton

It has come to our attention that it is possible that small group of mountain bikers is using the web site Strava to have “competitions” in various locations around the Santa Monica Mountains National Recreation area.

Strava allows you to track and upload your outings onto their web site via a GPS tracking device. The data ncludes the time it took you to traverse a particular route. It seems that some mountain bikers are using this feature to create a “time trail” competition and posting their times to see who is fastest. Obviously, trying to go as fast as possible on our shared use trails is not acceptable as it can endanger other users, including but not limited to mountain bikers. In response to this situation, we have learned that National Park Service rangers will be intensifying their presence at locations known to be experiencing this time trial scenario, Cheeseboro Canyon Park in Agoura Hills being one of them.

Currently it is the policy of the Santa Monica Mountains National Recreation Area’s managing agencies that events that displace or affect the safety of other trail users on public open space trails are prohibited. If you want to race, go to a sanctioned race ( If you want to go fast, go to a location that is set up for high speed mountain biking, such as Mammoth Mountain (

Light Rain Provided Perfect Dirt for CORBA Kids Ride

Saturday, November 5th, 2011

Though it was a small group who showed up for the November CORBA Kids ride in Cheeseboro Canyon last Saturday November 5, their enthusiasm ran big.  Light rains the day before provided perfect riding conditions.   The summer dust was lightly packed, the skies were clear and blue, and the temperature was pleasantly brisk.

After our standard greetings, 3 adults and 3 kids saddled up and headed out. Dave rode up front with Ethan and Nolan, John rode with Josiah, and Kat was sweeper and some-time photographer. When we got to “The Bees,” John guided the kids one-by-one through a small water crossing; the kids did great! We continued on until we hit 3.25 miles before taking a break and turning back. Most of the kids were tired after a total ascent of 500 feet.

During the break, John demonstrated the strength of his Kevlar gloves. He dared the kids to hit his gloved knuckles with a rock, and they each took a turn. After watching a large group of adult riders negotiate some technical rocky areas, the group saddled up. Most of the kids were uncomfortable riding back down some of the rockier sections, so they learned another lesson in mountain biking: There’s no shame in walking! Once we got past “The Bees,” everyone enjoyed the mostly downhill ride back to the parking lot.

After the ride, the kids snacked on chips and cookies, while the adults compared bike racks.

Check out the photo gallery of this ride. Next ride will take place Saturday December 3rd in Sullivan Canyon; meet on the Brentwood side: . Hope to see you there!

Reply to Cheeseboro Canyon Responses

Sunday, February 6th, 2011

Thanks to all of you who posted your comments regarding our recent blog posting about the possibility of mountain bike access being threatened in Cheeseboro Canyon.

Although the “bonus run” damage may not look like much to most users, one of the top mandates of the National Park Service (“agency”)  is resource conservation. Whether you agree or disagree with the agency, if they view it as damage, they are responsible for mitigating that damage. I’m not saying I agree with their assessment, but if that’s their job, we have to respect it. Part of the process is becoming as educated as possible and working with the land managers to the benefit of all concerned, something CORBA has been doing for 24 years.

One responder brought up the question of damage created by horses as they walk on the soft/muddy trails. This is a very good point, one which I brought up with the agency in an email I sent earlier today (see below). I will report back on their response. CORBA representatives also have a meeting with agency representatives in February and we will make sure this topic is revisited.

For those of you who requested examples and locations of the bonus runs, I went there yesterday and took a few photos (see below). It’s not all of the examples, just the more pronounced ones. A couple of the “bonus runs” are actually mud pit bypasses, which hikers seem to be using as well to go around sections where horses have chewed up the trail. Sorry to not have GPS coordinates attached, but if you ride Cheeseboro with any regularity, you’ll know where they are.

As far as the short section of single track that parallels the fireroad that the agency has posted with a sign, I don’t get it either. But again, just because something has been there for a while, it doesn’t mean that the agency doesn’t view it as a problem.

E-MAIL FROM MARK LANGTON  TO NPS REGARDING TRAIL DAMAGE IN CHEESEBORO CANYON:        Several people have contacted CORBA regarding the recent sign posting closed the short singletrack section of trail in Cheeseboro that parallels the fireroad about .2 miles from the parking lot. Also, a ranger recently commented that the “bonus runs” in Cheeseboro are causing the agency to be concerned about future mountain bike access. We have also noticed that several of the bonus runs (some of which are really mud pit bypasses) have had branches put in place at either end.

We certainly want to protect the resources, but the question comes up about horse use in the parks and the damage caused by walking on the soft/muddy ground, which causes as much if not more damage and subsequent maintenance workload than the off-trail routes caused by bicycles. In fact, if you look at a couple of the bypass trails (and I know this from experience as well), they are bypassing the horse hoof holes created by horses walking through the mud, and hikers are creating/using them too. Damage is damage, and if one user group (mountain bikers) is being singled while another is not being held accountable (equestrians), especially when the equestrian group represents a much smaller percentage than the mountain bike group while creating much more damage per user, it seems unfair at the least.  Please advise.

Mountain Bike Access Threatened in Cheeseboro Canyon

Thursday, February 3rd, 2011

Recent comments by National Park Service ranger personnel indicate that resource damage caused by mountain bikers in Cheeseboro Canyon Park in Agoura Hills could threaten future access.

Over the last few years increased off-trail “bonus runs” have been created by mountain bikers and is a fairly serious breech of accepted activity. These bonus runs include parallel routes along designated trails for the purposes of creating a more challenging experience.

Bonus runs are a direct example of mountain bikers not adhering to posted designated trail routes. Continuing this practice could lead to access restrictions. Please think twice about going off-trail: A little personal fun now could cost a lot of fun for a lot of people in the future. Remember, your individual actions speak for the entire mountain biking community.
