Welcome to CCCMB

We Do Trails - Join Us!
Our Mission

The mission of Central Coast Concerned Mountain Bikers (CCCMB) is to expand the network of sustainable and enjoyable trails in SLO County and to maintain the trails currently in use. Since 1987, we have worked with California State Parks, the National Forest Service, San Luis Obispo City, and San Luis Obispo County in designing and building new trails and maintaining existing ones. 

Help us keep the trails of SLO County open and fun to ride by joining us for trail work. Also, for good karma, be cool with others on the trail: always ride in control and don't run over people, animals or plants.

"Trails aren't BORN - They're designed and built by volunteers - You and I"

The Next Big Trail Building Project...  SBS@MdO

Come join us on Super Bowl Sunday at 9am at Montana de Oro (Spooners Cove), for the "Super Bowl of CCCMB Trail Building Days".  More details in the article on the right.

Other Weekly Trail Building Events...   

Every Monday work is being done on the new Sapwi Extension Trail at Santa Margarita LakeThis trail will go west from the Sapwi Equestrian Camp on the lakes' north shore to Blinn Ranch Trail across the lake from the White Oak Boat Ramp.  Currently we are boating volunteers across the lake to the work area.  Yes, it is a drive out to Santa Margarita Lake, and the work site is remote but in the opinion of some, this will be one of the best trails in the county when it is finished.   CCCMB President, Joe O'Donnell goes out most Mondays and you are welcome to join him.  Please email him to let him know you're coming at jodonnel@slocity.org

Every Wednesday morning at 8:30 am, a crew leaves from the east edge of the Home Depot parking lot in San Luis Obispo to work on the new trails in the Irish Hills Natural Reserve.  This is a great way to help out on SLO County trails a good opportunity to work with a seasoned trail crew.  No need to RSVP.  They typically finish work around noon.

Pismo Preserve Update

Good News – There are approximately 12 miles of new multi-use trails in everyone’s future!  Since September CCCMB has been working closely with Land Conservancy staff, the Wallace Group, equestrians and hikers to develop a trail system, which meets everyone’s needs.  The end result of that collaboration is a plan for a 12-mile network of trails that will be sustainable, fun and safe for all users.  The network has loops of different lengths providing trails for a range of experiences:  short or longer and easy to more difficult.  All with a spectacular view! 

Other News – The L. C. is dedicated to creating a quality project that will serve both the public and the land well.  It takes time do develop plans for two bathrooms, two parking lots, trails and to acquire the necessary Agency approval for those improvements.  Construction takes more time.  It seems likely that the earliest start date for trail construction is sometime this summer.


Central Coast Concerned Mountain Bikers are the main trail designers and builders in SLO county.  We have been working on local multi use trails in this county for over 27 years.  Over the last two years alone volunteers under our direction have logged over 9,000 hours of trail work.

Volunteers working the Hazard Peak Trail - Montana de Oro

About 40 volunteers turned out between storms last Sunday to perform some badly needed trail work on both Hazard Peak Trail and Oats Peak Trail.  They spent the morning rebuilding worn-down rises and clearing out drains to help prevent erosion ahead this winters upcoming rains (optimistically speaking).  The group consisted of Mountain Bikers, hikers, equestrians and trail runners, who all put in some hard work on these multi-use trails.

Another part of the group took about 15 volunteers about two miles up Oats Peak Trail to rebuild a few of the berms that were broken down.  To help in the effort they even transported some large rocks to reinforce the foundation.

If you would like to help maintain trails in MdO State Park, keep an eye on our calendar for information about our "Super-Bowl Sunday Trail Day".

Trail Building School at Pismo Preserve

CCCMB really appreciates all the 150+ participants who turned out for the Trail Building School at the Pismo Preserve last weekend.  It was a huge success with lots of good feedback from the IMBA team as well as the "new trail builders".

Here are some links from the IMBA Trail Care Crew visit and a few pictures from the weekend:

160+ Volunteers at 
Trail Werks - Saturday!
6,000'+ of New Trail Built

More than 160 volunteers turned out in the early morning hours
to help build new trails at Trail Werks on Saturday

This year's volunteers collectively created more than 6,000+ ft. of new trail, ate some great breakfast and lunch BBQ food, and took away more than 50 raffle prizes for their efforts.  

A big thanks to the City of SLO, the many sponsors of the event and the organizers for making it happen.  And, a very special THANKS for all those who volunteer their time to help create lasting trails for our community to enjoy.

Recent Trail Workday - East Boundary Trail at MdO

The last trail workday (Sunday, Sept. 21st), was spent widening "The Chutes" near the bottom of East Boundary Trail at MdO.  Volunteers clipped back the brush that has been overtaking the trail during the past year.  A big thank-you to all those who worked Sunday morning, so that everyone who rides the East Boundary Trail can enjoy it even more.

Interesting Stats on "The Trails We Love"

Here is a link to an interesting article about mountain bikers, flow trails and trail etiquette. (8-28-14)

Oats Peak Trail is OPEN to bikers in M.d.O. 

The Oats Peak trail is now open to bikes, hikers and horses in the Montana de Oro State Park.  It is the second highest summit in MDO with both ocean and mountain views.  It offers a 10.8 mile round trip to the peak and back on a trail designed with mountain bikers in mind.  The 5.4 mile gradual ascent gains 1,325 feet of elevation with LOTS of panoramic views.

The old and new trails crisscross, but bike ways are clearly marked.  The last 1/2 mile of the trail has not been improved and it a challenge for bikers with a probably "push" up and a "fun" ride down.  The 360 degree view from the top is spectacular and well worth the push.
