Great hike starting at the ruins of the Cobb Estate, ending with the ruins of the historic Mt Lowe Railway and Echo Mountain, with spectacular views of Los Flores and Rubio Canyons, all the way to the ocean.

If you are a beginner looking for your first intermediate hike, this trail is for you: a well designed, well maintained, single track, easy to follow, friendly and popular, with a steady grade of about 12%.

One of my favorite hikes in the front range of the San Gabriels.

Great trail on a hot day. Lots of shade. Lots of water. Many cautious mountain bikers. Just a few bozos.

It's amazing how secluded this trail is given its location. It's also quite overgrown, so I recommend wearing pants, bringing a map, and giving yourself plenty of daylight. We decided to turn back about 0.8 miles in because we encountered a rattlesnake in the middle of the trail under some rocks. (We didn't want to deal with it on our way back down in the dark.)

Rubio Canyon is a lightly trafficked, hidden gem. The canyon is very steep, and within a hundred yards you go from suburbia to a rugged wilderness that is popular with canyoneers.

If you extend the hike a bit, you can reach a number of different waterfalls, one of them almost 80 feet high. Just be prepared for some bushwhacking and Class 3 scrambling. You definitely want hiking boots and long pants. You definitely don't want to bring your dog, and if you're afraid of heights, this is not your hike.

But the views are spectacular, and you pass some ruins of the historic Mt Lowe Railway. Very fun and very worth making this a destination hike.

Great hike! 4 hours with a lunch and some breaks in June. The trail was poorly marked but if you follow the river bed it will lead to the mine. An out and back just to the mine will save you a lot of elevation but the rest of the loop is very scenic (follow the river bed to the left of the first shack)! We saw two entrances to the mine, the lower was easy and the upper entrance was straight up a rock scramble about 25 feet. The top mine has a very deep visible tunnel. The river was very low and dry in some places.

Crowded and popular, yet fun social trail for quick half day hike near LA. Moderate and dog friendly. Nice views on clear days.

Nice challenging but easily doable trail for kids. Great view and opportunity to explore the ruins as reward at the end. Probably closer to 5.25 miles altogether. Heavily used on the weekend.

Excellent hike with a lot of things to see and got a nice sunset view at the end.

wow, great hike. it took us 5 hours with breaks

A little challenging with the 5 y/o but the trooper made it! Proud of her. Other than that, great hike with family and friends. Not too much shade either so properly prepare for it

Hiked this loop trail yesterday...weather in the canyon was perfect. Trail was in remarkably good shape compared to a couple of years ago after the station fire. If you hike in during summer start from the top and work your way down canyon where it will be much cooler. There was some water in the creek, some salamanders, and we only saw one other person as we were coming out of the canyon, which for a Saturday is amazing.

Tough hike, great views. The summit is beautiful and also a has an interesting history. A mind and body experience!

Went Sunday morning (5/26/18) and started at 7am. Not as crowded as I thought it would be and it was still cloudy and cool. Hiked to the hotel remains, then all the way up to Inspiration Point. This was my first hike of this distance, but the views of Los Angeles through clouds was well worth my complaining of how tired I was!! I see this page states that the hike is 4.9 miles out and back, but the tracking I used on my cell phone showed that it totaled 11 miles. Regardless, it was well worth it.

Love this trail. Such a beautiful end view. Vistas are 180> degrease at the too!

Great historical hike.
Heavy traffic on the weekends

Get there early. You will have to park on the street and the later you get there the further you will park from the trailhead. It’s a beautiful hike but it can get packed and the trail is well maintained but narrow. We hiked up to the hotel remains and I regret not taking the extra time to take the detour to inspiration point. Next time!

Oak and follow the sign for sunset ridge trail. Then you'll be on the trail that leads to the creek. Follow creek all the way up. Mines closed but it's a fun trail. Incline the way there. Decline the way back. 6.5 miles total

I hiked what I believed to be this trail this past Saturday morning, which was nice and misty. It made for a truly beautiful hike. I am not entirely sure where I made the wrong turn, but on my recording you can see that I did not hike this trail, truly. When I got to the gate for the access road about 7am, it was locked. I found a spot on the street down past the nursery and hiked up the road to the trail system. By the time I got to that point I was so wet and had been roadwalking for so long that I just took the first trail I saw. My total hike was around 4 miles out & back, and I came across both a dwelling far back in the forest, and a beautiful pool of water not far from the dwelling. (I do believe someone lives there currently - it looked that way.) I plan on doing the proper trail soon, but this was my favorite short hike to date.

Did this hike in early May and it was great! A couple of pointers though....
1) I was fooled by AllTrails YET AGAIN on the trail distance. Description says 4.9 miles but it is actually 6.5 miles. The site is usually off a bit but this one is off by quite a large margin so plan accordingly! I did this right around sunset and had to run the last 20 minutes to get my car out by 8pm.. (per the signage you will be locked in after 8pm).
2) The hike is pretty difficult in that it is steep & narrow in several spots w/ slippery gravel so wear hiking boots. I do a ton of hiking and would say this one is borderline moderate/hard. Decent elevation gain but well worth it.
3) Where the f was the dawn mine? There is a sign clearly marked pointing toward it however I ran around that area thoroughly and never found it. Still cool, just was racing the clock due to the distance and did not see what was pictured in some of the photos here. Bummer.
4) Overall beautiful hike. Doing the sunset portion, yes, during sunset made for great views and it really was one of the nicer trails in the LA/Pasadena area. There is a nice little picnic area toward the peak elevation on the sunset trail side & you can see DTLA. Very nice. The stream is really tranquil and there are fun wooden footbridges and rock jumping to keep things interesting on the dawn mine side.
5) Definitely have the trail map handy as there were several times I would have been lost without it. Lots of intertwined trails around here so be careful to stay on this one. :)
Happy hiking!

One of my favorites. Consistent elevation gain, gorgeous views sunrise or sunset. Gets busy, so time accordingly.

the hike to the top is all uphill and there's not much shade but when you get there it's worth the hike

Great hike. Started at 6:00am on Sunday morning and had shade all the way up and down from Echo Mountain. Narrow and winding trail with good inclines. A bit crowded but everyone I came across was courteous.

Narrow winding trail with steep incline makes for great workout, 2-3 hours up and down. Amazing views of San Gabriel valley and City. Best views and photos at peak. Wild flowers bloom in the spring. Arrive early to avoid crowds and heat. Plenty of neighborhood parking. Gets hot in the summer.

So far is one of my favorite hiking trails around LA, great views, nice walk, birds, people,dogs, little lizards, squirrels, picnics areas, camping places so good, and the arroyo is not dry at all

nice trail. great views when it is not smoggy. start early or after sunset as most of trail and summit do not provide shade. trail is very dry and dusty as well. no water or restrooms available either. very nice trail overall.

Moderate hike with some great views.

straight good point too hike

Great as a trail run, if a little steep to run on the way up.
