Mountain Bike Bill, Get the Dirt on the Dirt

San Clemente and Rose Canyons

San Clemente and Rose Canyons are a couple of open space preserves located in the Claremont Mesa area of San Diego.  The route depicted here is 16 miles, but you can squeeze out some more miles once you get out and see the area.  A beginner will find these trails to be somewhat challenging while an intermediate rider will find the trail system to be a lot of non-challenging fun. 

Directions: From the I-5 exit onto HWY 52 east and get off on the first exit (Clairmont Mesa Blvd/Regents Rd).  Immediately turn into the parking lot. Park and get ready to ride.

Hazards: Most of the trails here are beginner to low intermediate in nature. Please be aware there is lots of Poison Oak in the shaded areas. While this is not much of a problem on the primary doubletracks and the heavily used single tracks, if you get onto the less used singletracks you will find that the poison oak often infringes in the trails "air-space". I developed as sensitivity to the stuff back in 2003, so I spend less time here than I used to.

Ride Notes:

RoseSanClementeCanyon-9FEB03-01.jpg (75621 bytes)RoseSanClementeCanyon-9FEB03-19.jpg (125589 bytes)From the parking lot cross the stream bed and pick up the trail on the south side of the stream.  Head west which is also slightly down hill.   You will cross a streambed a couple of times which may have some water in it according to what time of year it is.   There are plenty of turns in the trail with some rises here and there.  The trail will open up from riding among trees into a narrow meadow which the trail follows along the edge. Throughout this ride there are many offshoots from the trail and many of them simply loop back to the main trail in a short distance.

(This will be a hike-a-bike for most).  Ride north in the culvert for a hundred yards or so and then exit it to the right (This is the first place you can exit the culvert). Once out of the culvert the trail splits again.  Straight continues back towards the way you came on the North side of the HWY52.  Take the trail left that heads north.   You will now have to climb the only significant rise of the entire ride.  It is very short but steep enough to get and intermediate ride working and challenge a beginner.

RoseSanClementeCanyon-9FEB03-05.jpg (88654 bytes)RoseSanClementeCanyon-9FEB03-06.jpg (88202 bytes)The trail continues as singletrack for a while and eventually will open up into double track.  The wide open meadow doubletrack  scene continues until at mile 5 you must cross a road (Genesse Ave) and pick up the trail on the other side.  About 1/2 to 3/4ths of a mile from this point the trail moves into an old streambed.  If you have not had the chance to ride on "baby heads" before you will be in for a treat.  (Baby heads are smooth round rocks about the size of a well... baby's head).   You will have about 3/4ths to 1 mile of baby heads to deal with of varying degrees.   Speed is your friend here, the faster you go the smoother the ride will be as you will "float" across the tops of them vice digging in between the rocks.  

RoseSanClementeCanyon-9FEB03-09.jpg (68507 bytes)RoseSanClementeCanyon-9FEB03-07.jpg (58673 bytes)Just after the baby heads you will pass under the I-805 freeway.  After passing under the bridge, take note of the trail on the other side of the railroad tracks that comes down a steep hill.  You will be coming down that trail later.  Follow along the double track on the east side the open area.  At mile 7.1 there is a trail that turns off to the left, cuts across the field and goes over to the rail road tracks.  Take this trail up to the tracks.  Once you get up to the tracks.   You will see a low spot on the hill side on the other side of the tracks.   After doing the common sense thing by watching out for trains cross the tracks and pick up a narrow singletrack at the low spot.  You will have to navigate and old bob-wire fence.  You will be picking up trail in the middle of a turn.  Go to the left.   

RoseSanClementeCanyon-9FEB03-08.jpg (57333 bytes)RoseSanClementeCanyon-9FEB03-10.jpg (64604 bytes)The entire area north of the railroad tracks is full of nice singletrack that  crisscrosses back and forth .  It is bounded by the I-805 freeway, the railroad tracks, and Miramar Road.  As long don't cross any of those you can't get too lost.  Once you are done playing in this area follow section of doubletrack along the I-805 that follows a set of power lines back down to the railroad tracks.   It will bring you down along the trail that you took note of early while going under the bridge.

RoseSanClementeCanyon-9FEB03-12.jpg (80889 bytes)RoseSanClementeCanyon-9FEB03-13.jpg (142957 bytes)Once back down by the railroad tracks, do not cross them just yet, instead follow a trail along the north side of the railroad tracks.  This trail will continue along all the way back to next bridge (Genesse Ave).  Cross the rail road tracks while under the Genesse Ave overpass (After looking out for trains of course).  Get up on the sidewalk and ride it a couple hundred yards and connect back up with trail on your right.   You are now back on the trail you came in on.  Return the way you came back to your car for a total of 16 miles.

NOTE:  There are many off shoot trails that are worth exploring that can add some significant mileage to your ride. Once you are familiar with the area you can connect several areas together in "Semi-Urban Epics".
