From the 210, exit on Rosemead bl. and go north(Towards the mountains). Rosemead bends west and turns into Orange Grove bl. Proceed and turn right on Altadena dr., then right on Crescent dr. and right on Pinecrest dr. The trailhead is on the right hand side. There's no parking near the trailhead on the weekends and and 2 hour parking on weedays. It's easiest to park around the corner and ride to the trailhead. The area is safe. There's water,restrooms, and picnic areas at Henninger flats and atop Mt. Wilson. Thomas Guide page 536 D5

Mt. Wilson Toll Road - I rode up to The top about 6 weeks ago & had to go try it again!...I had forgotten how hard it was for me! It seemed tuffer this time! heh-heh! Glad I did it. The road seemed a little looser than it was just 6 weeks ago which makes sense with no rain to pack the dirt down. ALSO it was graded around the Henningar Flats section which made it looser.

I DID IT! - Well I climbed the Mt. Wilson Toll Road Today! I would say the road is in pretty good condition. It is not too loose at all. One thing though Those pesky dear flies were "slightly" out of control! It made me want to throw a small bottle of bug spray in my pack for situations such as that! Other wise it was a GREAT DAY! The food or snack shack is open up there and they have some VERY GOOD sandwiches up there! There were about 50 people at that pavillion! I have done that ride many times over the years and this was the most people I have EVER seen up there! Kinda cool to see so many people enjoying the mountain. BUT I did not see one other biker at the top & "I think" I was the only bike to accend the trail to the top for the day as I did not see any other tire imprints in the dirt. The ride down was very fun and rewarding!

Dirt, snow, and ice - The trail was in a great condition after recent rain events. Rode up to Mt. Wilson with a CX bike. Trail was well-packed most of the way but snow appears about half an hour from Hanninger Flats then turned into slush and ice about a mile before the towers.

Pasadena Star-News Article: 05/13/2008

IT'S been a good couple of weeks for trail access in the front range of the San Gabriel Mountains.

First, a judge ruled definitively against the long-running, enormously misguided attempt by a small cabal in Altadena's La Vina Homeowners Association to prevent hikers from strolling where they have been since the 19th century.

That victory in Millard Canyon was celebrated with glee by many people of goodwill throughout the region, not a few of whom live in La Vina itself and who are going to be stuck with paying attorneys' fees because a small minority of their neighbors went off the deep end.

Also this month a Monrovia trail to which the public has long had access - if not from the 19th century, at least from 1971 - was ruled entirely public again by a Pasadena Superior Court judge.

It was another case of a homeowner misunderstanding what the public right of way means. The Sawpit Wash Trail runs alongside a county flood-control channel for about two miles, and is popular with hikers and runners. When one homeowner over 50 years ago refused to sell land for the channel, the county obtained a binding easement for the trail. The city of Monrovia had to sue to make a new homeowner at the property understand what an easement means; again, the city and the hikers won.

Good stuff. But what about the sad situation in which one of the most famous trails in Southern California has been blocked not by some ornery property owner but by a



landslide, and the powers that be can't seem to clear a way through?
That's what readers keep asking us about the massive slide that covers the historic Mt. Wilson Toll Road just past the bridge over the Eaton Canyon stream below Pinecrest Road in Altadena.

The slide occurred during the El Nino-driven rains of the winter of 2004-`05, when 38 inches of rain fell on the city, and many inches more came down in the mountains.

A quick glance shows that clearing the road - widened 101 years ago to accommodate the 100-inch Mt. Wilson telescope and closed to motor vehicles other than government ones since 1936 - is not going to be an easy task.

There are thousands of tons of dirt and rocks to be moved.

But it's been years now, during which the steep but lovely hike to Henninger Flats and on to Mt. Wilson has been not available to thousands of hikers and bicyclists used to its rugged charms.

So we called the man in charge of solving the problem, Frank Vidilas, acting chief of the Forestry Division of the Los Angeles County Fire Department, and asked him what gives.

The good news is that Vidilas sees an end in sight. The bad is that it likely won't be cleared until April 2009. That's because the complications, says Vidilas, are both natural and bureaucratic.

In the first place, there are six more landslides than the one visible from town farther up the road. In the second, a lot of agencies - including the city of Pasadena, which owns the land the first slide covers; the California Department of Fish & Game; the United States Forest Service - all have fingers in the pie. It's been decided that the county needs to take the lead in solving the problem, because its vehicles use the road most, to bring supplies to the firefighters in permanent residence in cabins at Henninger. (Now the supplies come in from the clear road down from Mt. Wilson, but that's a long way around.)

Vidilas is working to get yet another bureaucracy, the Federal Emergency Management Agency, to foot the estimated $1.4 million bill for a contractor to clear the landslides. He hopes to see work begin by this fall.

So do we. It's been too long a wait to see the important trail cleared

Mount Wilson- Henniger Flats - About a year after the landslide, I spoke to a friend who is a Altadena fireman about the trail and asked if/when it was going to be repaired. The reply (at that time was) the city was not going to repair the trail because it would cost a few million and the city didn't want to spend that type of money, but within the last few months, neighbors in that area say that they've seen bulldozer. So, who knows? Write to the city of Pasadena or Altadena

It's Doable - I hiked up to the Toll Road last September and with the excetion of a few small slides (after the big one) you can make it to Henniger. The gate from Crescent drive is locked so you have to go in through the park. Make sure you ride very slowly and give the hikers a lot of room since you're not supposed to ride in that area.

I was told by the ranger at Eaton Canyon vistors center that FEMA gave the USFS $1 million to repair teh Toll Road. Not sure when we will start seeing work on it but I will post something if I see anything being done.

Mt. Wilson Toll Road - Is this trail still rideable from Eaton Canyon to Mt. Wislon? Has anyone tried it lately? Thanks!

I rode the part from the bridge to Henninger flats yesterday (May 8, 2006). There is only one REALLY big land slide in the beginning of the trail. Although there is a narrow route which goes through it. Once you passed it, the road is totally rideable all the way to Henninger flats (there is another small land slide right before the flats, but if you make through the big one, it's not even worth mentioning.)
It looks like the road is being used by quite a few hikers. It's amazing to see how everything looks overgrown and abandoned, when it wasn't heavily used for around 2 years.

Since the gate is still closed, you have to go through the Eaton canyon park, please try not to annoy a lot of hikers and dog walkers, since technically biking is not allowed there. Noone is bitching about riding a bike there. You can technically walk it all the way to the start if you'd like to be nice.

landslides (still) - There's still a giant landslide just past the bridge at the end of Eaton Canyon, looks like it completely obliterated the toll road / trail entrance there. The Chantry Flats road was closed too. Too bad, I was looking forward to a good hike up to Wilson. Anyone know what's the best way to get up there besides the paved road from Hwy 2?

Toll Road Update - Does anyone have an update on when (or if) they are going to fix the trail and bridge? I went to the ANF site as well as the LA County site to look for it per Miznax's url, but could not find anything.

Thanks is advance.

Toll Road Singletrack - Hiked up there yesterday via Rattlesnake. Not too legal I guess, but many are hiking the trail. What used to be fireroad is now in places single track. There were some signs of bikes in places as well. Still don't know of a preposed clearing and opening of the trail.

Would be nice though!

Any word on repairing? - I wish I checked the trail posts before I left to ride this trail. What a mess! Does anyone have any info as to when this road will be cleared. I imagine that they have to wait some time for the ground to dry up and settle. If you have any info please post. If you have a link to a site from the USFS please share. I tried doing a seach but came up empty.

slide - Just had a feeling to drive past the trailhead. There is a huge slide you can see from the Gate at Pinecrest. It wiped out about 50+ yards of the road 25+ yards up from the trailhead. Looks like that alone will take a long time to repair.

Mt. Wilson Toll Road - Post Rain - Rode up the Mt. Wilson Toll Road yesterday morning (10/24) to Winter
Creek trailhead. Trip up to Henniger is pretty tacky, some rutting but
mostly unchanged and in good shape. From Henniger up to the first
ridge line there are one or two hike-a-bike sections as the trail has
some rocky sections and washouts - however, it's still fun and a little
more challenging than usual. From the ridge line to Winter Creek,
however, is a different story. The first few miles are nice but then it's
like riding up a dry creekbed. Many hike-a-bike sections and severe
landslides leaving the trail totally unrideable (even a careful hike
across) in some sections. As it stands, probably not worth it to ride
past the second ridge line (this is where you come out of the shade and
have a view of Altadena below before heading East bound toward
Winter Creek).

Overall fun ride and perfect given my time constraints (read family
plans) on Sunday morning. If coming down toll road, be very careful of
washouts and rutting above Henniger but have some fun!

Angeles Forest Trails - Hey, the Angeles Forestry Service is putting all their fire patrols in the canyons with cabins on weekends, so how will they know if we're riding on the trails?

Trail Closed to Public - I planned on doing this ride last week and showed up to the trailhead only to see that the gate was locked and there was a big sign that read "Forest Closed to Public." Duh, the news did report that the Angeles National Forest is closed to the public. I thought about being a renegade and riding up to the toll rode from the park, but that would be wrong. So I drove over to El Prieto and there was the same sign. Very :(
