Limeklin Canyon - Northridge/Porter Ranch Trailhead - #LimeklinCanyon
Limeklin Canyon - Northridge/Porter Ranch - Los Angeles County - #LimeklinCanyon
Take the 118 FRWY east (i think - towards simi valley) and exit on Tampa. Turn right off the frwy and head north on tampa untill it dead ends in the foothills (Cross street of seasnon) Park in the cul-de-sac at the end of Tampa. Ride west on Sesnon to the top of the hill and the trailhead is right next to the mailbox. The trail is an awesome 2.5 mile descent with steep downhills and stream corssings. I have seen 3 deer while i was riding - TRUELY amazing!!! Thomas Guide page 480 G6

Bridge out - The dirt bridge that went over the first stream
crossing north of Rinaldi was washed out by the
recent rains. You can carry your bike across at that
point and the next crossing until Recreation and
Parks makes the repairs (probably in the spring).

Limekiln - Horse Flats - Horse Flats = Olive Grove. See posting #14. They're west of Moonshire Canyon, east/south of Mormon Canyon. "Moonshine Canyon" doesn't go along Moonshine Canyon, but rather along foothill base betweeen Limekiln and Moonshine. The road to Horse Flats is the one you saw at the grove just above the debris collector behind the condos above Rinaldi. The trail to Horse Flats leaves the fireroad on the left and cross upper reaches of Moonshine Cyn. There's a corral at the "olive grove". Mormon Canyon, a privately maintained equestrian trail is behind there. Another way to get from Horse Flats to Browns Canyon is to go southwest (toward the city) up a ridge that looks like a giant take off ramp. From top of "ramp", where there's a cattle gate, it goes down, sandy, rocky, fire road along dry creek, coming out in back yards along Browns Canyon. BTW, Horse Flats on one map also covered the area along Sesnon where all the houses and condos now stand. Saw herd of sheep along there 5+ years ago, preRenaissance Estates etc. There's a back way to the water tank you saw , but now you'd have to go through the S&S equipment yard behind the Renaissance Homes. From there to Horse Flats is possible, but mostly by carrying or pushing your bike, up or along cliffs.

Limeklin Canyon/Moonshine Canyon - I took Limeklin Canyon from Tampa/Chatsworth all the way up to Tampa/Sesnon. Great ride, tons of bird and lizards, if your into that. After passing Rinaldi going north, I noticed that the concrete and dirt bridge is in very good condition. There are several smaller stream crossings that arent as great, but if your your a strong bunny hopper, it shouldnt be a problem. From Sesnon, I took Moonshine Canyon heading west and back down Porter Ranch Drive. Hopped the bent chain link fence at the dead end (not a big obstacle for anybody, and took Mission trail back into Tampaland (which is great for BMX). Moonshine Canyon had some very fresh tire tracks, but I also noticed that its also getting soft and sandy, which I really dont like. But I guess the horses appreciate it much more.

Off of Moonshine Canyon when you come to a great resting tree youll see a water collection concrete wash (also great for BMX). To the right of the resting tree is a dirt road gate. The fence to the left of the gate is bent down and easily accessable. On mapquest, it shows that this road easily leads into what I believe are the horse flats.

Here is my question. Where are the Horse flats. At Tampa and Sesnon there are several trails and Im just wondering where they go. The first one east of the Gas Co. guard house and at the very end of Tampa curves east. The trail dumps off into a culdesac (Mirkirk Dr) with another trail starting on the other side. Using mapquest I noticed that the trail leads off into Sesnon Canyon south of Aliso Canyon. I noticed that higher up the hill a winding dirt road. From the Mirkirk Dr trail can you catch link up to this trail if you press hard up hill? I noticed from arial shots on mapquest that this winding trails also leads down into Limeklin Canyon Dr (which is a private road, owned by the Gas Company). If you take the trail north it will lead to what looks like a large tank on top of a hill. Down the hill on the north side looks like a grove of trees. Is this the Olive Grove trail mentioned before?

A west of the Gas Co. guard house is a sign showing Moonshine Canyon and Limeklin Canyon and three trails.
The one on the far right takes you to fenced up dead end, but if you hop up a small dirt ridge there is an opening in the fence. Whats up with this trail? I was kinda intimidated because I know those utility companies are pretty serious about trespassing.

The middle trail starts off with a steep climb and two signs are posted indicating private property. Is it cool to bike there?

And finally the one on the far left is Moonshine Canyon which is what I took. That trail was OK. But naturally I had more interest on the other trails.

Why is there only one trail available and signs indicating two separate trails?

Where is the Olive Grove Trail? Where are the horse flats? Where are the old oil fields? I can see a whole mess of trails on mapquest a little further north?

If you go north on Sesnon/Porter Ranch D. I can see that a trail leads to what looks like a water tank. Can you still go up to the water tank? And take the trail into Browns Canyon?

Thats about it. I'm mostly curious about public/private property. The Oat Mountain, Olive Grove Trail, Oil Fields and the Horse Flats are probably what I guess just takes simple exploring. Oh yea, I forgot where exactly are the Indian caves with writings on the wall? I guess thats alot further west off of Topanga Canyon. Thats probably a whole nother area of exploration. Anyways happy riding!

Moonshine - I've tried to explore Moonshine Cyn. We need to do some serious trail maintenance. It would make a great loop if we could hook it up with Limekiln. Now that they have plowed everything west of Porter Ranch, we need a new ride.

Moonshine - Moonshine canyon is the canyon that is underneath the bridge due east of the intersection of Porter Ranch Drive and Sesnon. The trail goes about 700yards south then Dead ends. It also goes north a little bit, but I don't recall how far. The north half is mainly equestrian traffic.

Moonshine - Moonshine Canyon is just east of the park which is
on the southeast corner of Sesnon and Porter
Ranch Drive. I haven't ridden it for many years and
it was tough back then. There is a trail
(equestrian?) that starts at the east end of the park
and goes underneath the bridge. It used to go
south and then east from there and eventually end
up in Limekiln just a little north of Wilbur. Happy

Moonshine Canyon? - At the top of Limekiln Canyon is a sign that indicates Moonshine Canyon is to the west. I think that must be the Canyon just before you get to Porter Ranch Drive when heading west on Sesnon. But there doesn't appear to be a trail there? Was there once a trail there? Am I looking in the wrong place?

Limekiln Canyon - The dirt bridge over the first stream crossing north
of Rinaldi is back but the second crossing is
impossible. The creek bed is very deep and there
are too many rocks. The rest of the ride is okay
although there seem to be many more hikers and
horses than there were in the past.

Limekiln Canyon - The recent rains have wiped out the dirt bridge that
crossed the stream closest to Rinaldi and
deepened the second crossing to the point that it's
not ridable. If you don't mind walking across the
stream it's still a nice ride. A couple of mud
puddles higher up.

I live two blocks from this trail and ride it often. They have recently mowed the long weeds/grass that was growing all over the place. They have also graded the trail in a few places and repaired the two lower stream crossings. At the first wide crossing, they installed two large pipes and filled over them with dirt so you can now just ride across it like a road. (you can still cross in the water if you like) They also dumped a load of gravel onto the second stream crossing so you can ride over this as well without getting wet. It looks like they did these things to help hikers, there has been tons of activity on this trail latelty with many many hikers and bicyclists using the trail. Maybe I will see you there sometime!

Limekiln - This trail was recently destroyed by LA Co. bulldozers in an attempt to make it safer (yeah right). Be real careful, dirt piles blocking the trail have appeared out of nowhere!

Limekiln Canyon - Go West on the 118 freeway and get off at Tampa. Go North until Ranaldi. Make a left turn.
Go about 300-400 feet to the trail head. It's on your right hand side. Go down this wide concrete path until it turns to dirt keep going. After you pass the lunch area you will see a creek. Be prepared to carry your bike over. It's about 20 feet and there is a log to walk across but it's real wet. After that stick on the dirt road. You'll come up to a road again. Race across to the continuation of the trail on the other side.It's a great ride.

Limeklin Canyon - To the north of Rinaldi there is a gate on to an old decaying oil field road. Follow it all the way up to Sesnon. A beautiful ride with lots of trees and a nearby stream. The barriers at the bridge construction are gone. There is much storm damage but it is still quite passable. There is usually much foot traffic so be courteous. WORD OF CAUTION: if you like to descend from the top first, be cautious if you have not been there since the rains. What was formerly two lane asphalt is now wide single track with 20 foot shear drops into the stream.

Olive Grove Trail - From the top of Sesnon, go north on a dirt road across a small flat, then turn left (west) in a grove of walnut trees. Continue up this road past a few curves and a moderate climb followed by a flat stretch. At the end of the flat, a trail leaves the road and heads west. This junction is often marked by a duck (pile of rocks).
The trail descends to the west, crosses a creek, then climbs to the south. When the trail bends west again, you enter a broad, grassy saddle between two hills. Past this saddle, descend to a flat with many horse trails, a corral, and a grove of olive trees. On the west edge of the flat the trail turns south and follows Mormon Canyon all the way down to Brown's Canyon Road, which returns to the San Fernando Valley at DeSoto and the 118 Fwy.
If you parked at the top of Tampa, the easiest way back is to take the Mission Trail, which parallels the 118 Fwy. on it's south side. Start at DeSoto one light south of the 118 Fwy. Go east from DeSoto and continue on the Mission Trail until you reach Corbin Ave. (a bridge over the freeway near a very large church). Cross the freeway to the north and go right on Rinaldi. Make a left on Tampa and ride back to the top.
IMPORTANT NOTE: This trail is heavily used by equestrians (horsey-back riders), so use caution around blind corners, and remember to be courteous and friendly. Horses become nervous and dangerous when confronted by jerks!
