A great hike in the lower San Gabriels to incredible vistas, forested mountain canyons, and the ruins of a turn-of-the-century mountaintop resort. Bonus enjoyment for history buffs, in the form of plaques and markers placed along the ruins and the route of an old railroad through the mountains.
The Basics:
- Distance: 10.4 miles
– Elevation Gain: 2740 feet.
– Time: 4 hours, 40 minutes
– Trail Condition: Very good. The Echo Mountain trail is well traveled, but well maintained. Castle Canyon has a few tricky parts, as does the middle Sam Merrill Trail, but nothing that should get anyone in trouble if they’re paying attention.
- How To Get There: From the 210, take the Lake Avenue exit north from Pasadena into Altadena. Continue on the road as it climbs a hill and park near the sharp left hand turn outside the Cobb Estate. You do not need an Adventure Pass to park on the street here.
- Map It
The Notables:
- Great ascending hike with plenty of opportunities to add on to your distance.
- Well-preserved historical ruins of a turn of the century resort hotel — more history than you’ll see just about anywhere in L.A.

Echo Mountain at EveryTrail
Map created using EveryTrail: GPS, Travel & Geotagging!
Hiking from Altadena to the ruins of the Echo Mountain resort was the first double-digit hike I ever finished, and I figured this weekend would a). be a good time to revisit and b). the trail would serve as a nice reintroduction to long-distance hiking to my legs … without the added calf-murder of the Mt. Baldy ascent I’d been weathered-away from last week.
I drove out to Altadena and parked off Lake Avenue. One of the first things you’ll see on the trail is a marker placed by the Altadena Historical Society, marking the entrance to the former Cobb Estate, and the Echo Mountain trailhead. You will see many more plaques along the way. The Historical Society has really done a fantastic job of researching, maintaining, and marking all of the points of interest along this route — and there are plenty of them.
The Cobb Estate belonged to a wealthy lumber magnate, and had several gold mines and water wells on its property before the buildings were completely razed in 1959. One year later, the Marx Brothers bought the land and wanted to turn the area into a cemetery. Luckily, students from the aptly named John Muir High School bought the land and donated it to the Forest Service. Now the land houses several miles of equestrian trails, a small botanical garden, and the entrance to the Echo Mountain Trail.
The trail crosses a flood control area and begins zigzagging its way up the southwest base of Echo Mountain. This section of the trail is very heavily-traveled, but is in excellent shape – especially for such a popular trail. The path is very well maintained, and I only noticed a few minor examples of trail trash on the way up. The grade is nice and easy, too — it’s about 3 miles from the bottom of the mountain to the resort ruins, at just over 1400 feet of incline. There’s a lot of switchbacks, yes, but you’ll feel like you’re making enough progress where it won’t bother you.
The trail does get more rugged the further along you hike, but nothing’s too bad on this stretch. If you’re hiking in the morning, you’ll get plenty of shade while climbing the west side of the ridge — otherwise, you’re not getting much of any shade. The first time I hiked this was in the middle of May in jeans and a long sleeve shirt. Needless to say, I lost a lot of water weight that day.
At around the 3 mile mark, you’ll reach a plateau and come upon a silver plaque from the National Register of Historic Places — which is always a way to catch my eye, if you’re ever wondering. It marks the section of the trail where you’ll meet up with the old grade for the Mount Lowe Railroad – a twisted series of cliff-side rails that used to bring paying customers to the Echo Mountain Resort from a nearby stop-off point.
Today, all that’s left are a few sections of iron track, the grade, and some abandoned gears near the old hotel…
The hotel itself is almost entirely gone, but a series of plaques and laminated photos around the site does an excellent job of recreating the splendor of the place in its heyday. At the main foundation of the Echo Mountain House, you can still easily make out the different rooms on the floor plan — and you can also see Inspiration Point in the distant mountains (in the saddle on the left). But you’ll probably have more fun imagining yourself at the same site at the turn of the century, comparing the old pictures with what’s left over.




If you want to make some noise, you can even walk around to an old ‘Echo Phone’ — basically just a ground-mounted megaphone that you can shout through to hear an echo. There was another one installed up at Inspiration Point, so patrons could yell to each other. The local wildlife must have loved it.
When you’re done learning and exploring, head back the way you came and hang a right onto the Castle Canyon Trail. This is a thin, rugged, fairly secluded stretch of trail that will take you far from the (relative) crowds at the old ‘white city’ ruins and deep past Rubio Canyon into the narrow, steep Castle Canyon.

There are a few stretches along this trail that I remembered as being fairly harrowing when I first started hiking, but this time along I didn’t even notice them. Once the path gets into Castle Canyon, though, it doesn’t take much time climbing up and out of it. It’s a steep, switchbacked, leg-burner. But the great thing about it is that you can’t really see the Inspiration Point pavilion until you’re almost there. So when you’ve just about lost your motivation, you get it all back again in one nice visual.
At Inspiration Point, you can get even more of your history on with a few more plaques, and take a look through some restored "finding tubes," which show viewers a certain location on the horizon — if you can cut through the haze.

From here, you can explore the site of old-time Sunday services, or keep traveling up another old railroad grade to the site of another burned down hotel at the Mount Lowe campground, and continue on to Mount Lowe — or you can take the Sam Merrill trail back down to the Echo Mountain ruins.
The Sam Merrill Trail is another treat to travel down — the first section is entirely on the north side of the mountain. The trail is cool, rugged, and well-shaded — which will surely be a welcome environment after trudging up the Castle Canyon Trail.
On the south side of the mountain, though, the trail returns to shadeless chaparral, and has a few sections with deep gouges — both from water erosion and mountain bikes. Just north of the Echo Mountain hotel, you can also stop off at the ruins of an old observatory, and gaze down on the L.A. that is while sitting near the L.A. that was.
Read more about the Mount Lowe Railway, and its major investor Prof. Thaddeus S. C. Lowe — a New Hampshire self-taught meteorologist, chemist, and Chief Aeronaut of the U.S. Union Army Balloon Corps during the Civil War. Really interesting guy.

Thank you so much for your website! Just hiked Echo mountain last night – and wouldn’t have known to do it without your recommendation. I was on a business trip from the East Coast, in LA for just two days, so yesterday afternoon I changed out of my suit and hiked up the mountain. For an advanced beginner it is a moderately – to easy – hike. Beautiful vistas. I was lucky to be hiking later in the day, so I was up on top for the sunset! As I was descending (and grateful for a pretty full moon) I ran into a few folks hiking up. So it is a popular trail, but not so popular that you can not enjoy the nature. The trail is spectacularly well maintained, and I only saw one piece of trash (which I took down with me).
Thanks for the great website! You made my day!
Hi!
I’m planning on doing the hike to Inspiration Point this coming Saturday.
Starting at lake Ave. Can you clarify which trail to take? I’m a newbie hiker…
and I want to make sure I’m not taking the wrong trail from the historic remains..
Thanks!
JT
@JT: Make sure you bring sufficient water (I recommend 3 liters) and something to snack and/or lunch on. Also, if you’re planning to hike to Inspiration Point, bring some kind of light sweater (Polar-tech) and/or windbreaker. This time of year it can get kind of nippy/windy up there. The weather Saturday is forecasted to be sunny and cool.

Then click on the “Basic Info” link, then on the end of the “Topo Maps” text, you will find another link for a printable trail map. My recommendation is, once you get to the Echo Mtn Ruins, take the Castle Canyon Trail up to the Inspiration Point Ramada. It’s pretty flat for the first mile, then the trail starts to ascend via a series of switchbacks the second mile. This is the hardest part of this hike.
Once you get to the Ramada, you can either head back down the Castle Canyon Trail or head north for a few hundred feet on the dirt road and on your left, you will come to the junction of the Sam Merrill Trail. Take that and head west and in about and hour or so, you’ll circle back to the Echo Mountain Ruins.

hi,
I now live in Escondido, CA. However, at age 12 or 13 in 1986-7 my father drove me up to Mt. Lowe many times and I was just enthralled by the whole experience.
We hiked the Sam M. trail at least half-a-dozen times back then, Castle Canyon, the original rail-bed, Mount Lowe Tavern site, the peak, etc. etc.
I LOVED the peak at Mount Lowe. It was SO high up and there were locator scopes up there at that time (not sure if they are still there, tho). We even drove the Red Box road to Mt. Wilson and went that way through the 1941 tunnel under the mighty San Gabriel Peak and Mount Markham.
At that time, there were NO “historical markers” designating anything!
The best trail in that area is the so-called “Mount Lowe West Trail” coming down off the peak of Mt. Lowe. Does it even exist now? It was beautiful! SO SHADED….lots of leaves on the trail path.
Also, back then, there was no cover roof or ANYTHING except stone foundations at Inspiration Point…..a very quiet place in 1986.
Anyway, I mentioned the memory to my dad recently and his response was that…”They have probably put a McDonald’s up there by now” LOL
We also went to Eaton Canyon a number of times (before the graffitti) and have hiked the Idlehour Trail to Mount Lowe……13 miles round trip. I’ll tell you, my dad was EXHAUSTED after THAT one! :)
I have a few books and old maps of Mount Lowe that I used to study with complete fascination.
Sincerely,
Matt
Wow, Modern Hiker thank you so much! A close friend and I were wanting to find new hiking destinations and stumbled upon your site…..amazing job! We went out for a hike last week, and while having trouble accessing your site via mobile we just decided to go blind. I excited at Lake Ave and headed north hoping to find a trailhead, which there was. Not knowing where we were going we stayed to the left, leading us up to a covered reservoir of some sorts. We took a small trail on the right of the reservoir, which was a nice hike down to the creek. There was a small canyon (dry creek bed) off to the left that we decided to explore. It was a nice hike at first, but the canyon disappeared and left us with a sandstone mountain to climb, which was okay until we reached the summit…..the rock just started falling apart under our feet. We would look over at the switchbacks on the next mountain over, and all the people on them, and almost wish we were there, but we just kept ascending. At the top the ground really started breaking apart, but through teamwork, caution and determination we made it to the top. Bloody, ashen and dirty, we made it. It seems this path butts right up next to the burn areas of the station fire, and one tree that allowed us to the to the top was completely burned. On the way down we were just glad to be intact, but a few hours later all we wanted to do was do it again. We may tie a rope on to the tree next time to aid anyone who wants to reach the summit, as we literally felt like we were just going to slide off the mountain.
Just curious if anyone else had taken this route. And much thanks for developing this site. I see little advertising, is there anything any of us can do to help? I’d hate to see this site not be updated in the future. You are awesome whoever you are Modern Hiker. But thanks to your site, now we know how to find the real trail next time we venture out (and don’t have a death wish)
@kompozr: Seems y0u violated the number 1 rule of day-hiking; bring a map of the trail, compass and plan the hike, hike the plan. I can’t believe you missed the trail to Echo Mountain. Now I know why Sierra Madre Search and Rescue has been in business for 60 years.
Anyway, if you do attempt this hike again, when you get to the trail register, go north about 50 yards then across the stream bed to pick up the trail. From your posting, it sounds like you never made it to the Echo Mountain ruins.
Yes Hiker Bob you’re right! But as a kid I grew up in the forest, and for a portion of my upbringing I had the Appalachians in my backyard! So while I may have violated the number 1 rule for hiking, this was much more of an exploratory romp in the foothills, like when I was a kid, and it was fun!
But seriously thank you, so excited to try the 10 mile loop and explore the ruins. Will definitely heed your advice my next trip out…..which we are going today. I’m a little nervous, hoping the mountain wasn’t beat up too badly in yesterday’s rain.
hey bob,
just a quick question……does the “Mt Lowe West Trail” still exist coming down off the peak? My dad and I used to hike this one back in the mid-80s. It was pretty worn and covered over at that time.
