Short and moderately strenuous. Good for a quick escape from the city. Most of the trail is sheltered by trees until near the top and not too many people use it's pretty peaceful relative to other more popular trails in the mountains.

There are some cool city views from the top of Mount Disappointment but otherwise it's not worth the detour.

Small amount of free parking at the bottom of the trail: according to the rangers you don't need a Forest Adventure Pass for this one.

Great hike last nite and way to step into my birthday..As I keep doing this hike weekly, I definitely feel a positive difference in my body and mind and its conditioning me to level up with ease onto longer and higher altitude trails.

Yes it’s been so hot this summer!! BUT this trail is nice and shady if you start as early as 6am. You would definitely need all terrain/hiking shoes. WATER and snack as well. Too many mountain bikers so Earphones headphones is not a good idea. Due to recent fires the view wasn’t as good but will definitely comeback!! Really liked the trail and if you’ve never hiked be ready for a great uphill downhill leg workout! :))

This is the best hike I’ve ever been on! It was so beautiful, you see everything from a stream, huge rocks, wildlife (we saw a huge snake on the trail) AND there’s a bunch of shade. Not to mention, we only saw about 4 different groups the whole time we were on it, which was a Saturday. It was a little hard to find at first but man, id recommend this trail to anyone!

Easy and very nice. Rock, woods, very small rivers... A variety if elements to enjoy. The ride. Excellent for kids that will trigger their imagination.

Great hike. I was tempted to take a star off for the amount of fellow hikers. My friend and I were slow, so we were constantly moving to the side to let others pass (our problem, not theirs). However, the hike itself is worth five stars. The "destination" at the end was fun and the views were great. We started at about 6:45 am and were in shade most of the time, which was wonderful in the SoCal summer.

This is a definite "share the road" experience. Equal numbers of hikers and mountain bikers. Most bikers were considerate (had bells and let us know how many were still coming) and friendly. However, there were one or two that flew around the corner and nearly mowed us down. One guy said "My bad" as he flew past us--if he had a bell, we would have heard him coming--get a bell, dude! My friend and I started at about 6:45 on a Saturday morning. We actually went counterclockwise, not on purpose, and only did about the first 4 miles, then turned around. It was a great hike and we will do it again, for sure. (Next time going clockwise, so we can actually see the stream.) There are a couple of places where the trail narrows or has a recent scree pile to navigate over, but all-in-all, a lovely hike. About 50% has cover and is cool. The steam on the side we went was a trickle and dry in many places--but it's august, so..

we met up slightly after the sunrise for a relatively cool hike, despite the season. The beginning of the trail is paved, but quickly hits dirt. The trail eventually finds sanctuary from the sun as the canyon narrows. It’s a pretty easy trail, and I recommend it for any beginner looking to lengthen their hike. the area by the mine is nice and shaded. The hike to the mine is relatively short, extend it for the full sunset loop trail.

Hope you enjoy!

overgrown and unmaintained, would recommend having the city maintain the trail a bit, this little canyon can get sketchy

really good hike.
I actually did 12.4 mile total.
I started from Sam Trailway worked my way up to Inspiration
( I took the longer way) I liked the challenge. Came back down the same way I went up. You definitely need at least 3 or 4 liters of water in a hot day. Took a sandwich and orange and u survived lol.

Yes this hike is recommended for advanced hikers.

Great trail, although a little overgrown. The atmosphere shifts several times throughout the hike, keeping it surprising and interesting. BRING: bug spray, the mostly-fired river bed is a mosquito haven. Also, perhaps booties for your dog too - as the asphalts the summer (it was 96 out) on the way back will burn their paws.

We met up slightly after the sunrise for a relatively cool hike, despite the season. The mountain ridges on the way up shielded us from the sun for the most of the ascent, and a bit cloud cover was an extra gift as well. The views on the way up are unparalleled, both of the San Gabriel Valley, JPL, and the San Gabriel Mountains. Once at the top, there sits the ruins of an old resort, the Echo Mountain House. There is a super cool Echo Phone towards the end of the ruins, past the water basin, which has some bright color graffiti. There’s a lot to see up here, not to mention the panoramic views of the Los Angeles area. The whole hike took about 3 hours for us, with a break at the top. I highly recommend this one. It’s a medium difficulty trail, because of the ascent, but probably a good transition for beginner to intermediate hikers. I’m definitely coming back, but I want to try some of the longer routes, possibly from the Sunset Ridge Loop Trail.

Hope you enjoy!

no waterfall, no water at all right now. July 24 2018. A very overgrown trail, wear pants and good hiking shoes, sunscreen. The hike involved climbing rocks while slipping around. I will be back when there is water.

Great family trail, lots of shade, cool for summer time.

Nice hike with the younger kids...

Attempted my 1st nite hike ever at 10pm last night. Facing the city lights ,
one foot in front of the other, headlights on , hiking backpack equipped with 6bottles H20, snacks , battery pack and cell phone charger. I trailed with hiking poles the scenic switchbacks. I recommend to focus light on ur step ahead as you may trip or step on a innocent tarantula. Take breaks to bring your heart at a cool beat and breath in and breath out slowly when needed... Hydrate, Hydrate, Hydrate..once u make it to the top , u can reward yourself with a cold one

Leisurely hike with not a lot of foot traffic for a weekend. There are a good amount of mountian bikers though which can get hectic. What's nice is that you can hike along a creek and easily find wildlife like tree frogs and toads.

Variety of birds as well. Lots of poison oak so be aware.

First of all the trail is 8 miles long not 6...
If you want a relatively short but tough trail, this is it! After the first 0.5 miles the trail becomes steep uphill for the next 3 miles. It’s not a popular trail and at times it can get lost in the overgrown bushes and plants. However, this is a great trail if you want to sweat to the point of your knees sweating. We’ve started at 6am and by 8:30 we were at the peak. There is a steep downhill for about 0.3 miles from the peak then it’s a straight hike for about 1 mile to the Inspiration Point. The second part of the loop is not-so-steep downhill on a busy trail until you get to the point where you need to take a small trail that branches out of the big one. That’s a steep, not popular, overgrown trail but it takes you right back to the residential area where you started from. Great trail for a difficult workout and the view of the whole LA County at Muir Peak is phenomenal !
Take LOTS of water (I went through 3l of water and 1l of Gatorade) and hiking pols because you will definitely need them. Oh and also make sure you wear pants not shorts because the plants/bushes will destroy your legs :)! Enjoy !

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.

it was a nice little hike but not much water this time plenty of shade and friendly people

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

This trail starts off easily enough as a wide track through the haunted ruins of the Cobb Estate. (Google John Fleming's writeup, or check out Atlas Obscura for the history.)

Past the reservoir, the trail totally changes character, to a narrow, cliff-hugging path that requires some scrambling and bush-whacking. More "dog accessible" than "dog friendly." Be prepared to help your dog over rocks, and to pick out a lot of burrs afterwards.

This is one of my favorite local hikes! It can be done as a lollipop loop using the Sam Merril Trail as the base. When you reach the top of the Sam Merril Trail you can take the Castle Canyon Trail (which is really awesome and wild but pretty strenuous the 2nd half). Or you can stay left and keep going up the mountain about 3/4 of a mile on the Sam Merril Trail until you hit Mt. Lowe rd. Then make a right and take that about 2 3/4 of a mile until you hit the Mt, Lowe Campground. And then only 1/3 of a mile more up to the right to Inspiration Point. Once there you can go back down the way you came or do it as a loop. The Mt. Lowe Rd. way is a little longer but not as steep. I like to do this hike as a sunset hike...the views are amazing. I usually make it back to the halfway point near the old hotel as night has fallen. The views of the city at night are breathtaking.

A fun little trail with a few stream crossings that's easy to get to and easy to follow. The best part is that a majority of the trail is in the shade, perfect for a summer morning hike! Get there early because parking is quite limited and you need an adventure pass.

nice hike smooth trail beatiful view at the top

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.)

This is a nice low impact hike. Very kid friendly.

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.
