There aren’t that many hikes that give you great views of L.A., Orange County, the Hollywood Hills and sometimes the ocean and San Jacinto range–and allow a chance to visit some So Cal history–but the trip to Echo Mountain via the Sam Merrill trail does.  Before Disneyland and Universal Studios,  the Mt. Lowe Railroad was one of the L.A. area’s top tourist attractions, and you can still see traces of it at the top of Echo Mountain.  Few places that are so conveniently located give the panoramic views that Echo Mountain does.  It’s a very popular trail, and no matter when you hike it, expect some company.

From the corner of Loma Alta Drive and Lake Avenue, follow the trail east.  A driveway branches off to the left but you head straight and descend slightly before picking up the Sam Merrill Trail.  This trail begins switchbacking steadily up the hill, taking in wider and wider views as it climbs.  If you have a fear of heights, this might not be the best hike for you; some of the switchbacks are pretty abrupt and the trail gets quite close to the edge of the canyon.

At about 1.3 miles the trail swings over to the east side of the ridge, allowing a nice view down into the canyon. You continue under some power lines, ascending the switchbacks. After a little over two miles of ascent, you get a nice bit of shade from some chaparral as you traverse the west side of the ridge.

At 2.5 miles, the Sam Merrill trail branches off. Stay straight and make your way to the Echo Mountain summit.  Here you can see old railroad gear, read information on plaques describing the history of the area, and of course take in the great views.

If you have time and energy, you can continue farther, retracing the route of the Mt. Lowe railroad.  However, most hikers will probably find the trip to Echo Mountain itself to be quite the workout.  However far you go, it’s definitely an enjoyable way to burn some calories.


  1. The Mt. Lowe railroad grade is still under the fire recovery closure order. Lots of people are hiking it nonetheless, and the closure stake was removed by enterprising hikers months ago. But it is still officially closed.

    The only legal paths currently available beyond Echo Mountain are up the Castle Canyon trail to Inspiration Point, or down into Rubio Canyon. The latter is very steep, and would leave you about a mile from your car. It also connects to a couple of waterfalls in Rubio Canyon. The former is strenuous, but gives you and even better view of the world to the south, assuming the skies are clear.

  2. I did this one as a novice hiker back in the early 2000s and absolutely loved it. The ascent while crossing the big powerlines was breathtaking. Of course, for a seasoned hiker, I’m sure this would be small potatoes, but it’s still pretty amazing to me!

    Of course, we had no poles and had to take frequent breaks on the way up. Those switchbacks were pretty tough! But it was nice to have mile marker posts along the way; I’m not sure if those are still there now.

    The most exciting things were the views and the skeletons of the old funicular railway and lodge. They’ve got picnic tables up there, too, with a lot of shade, so it’s a pleasant place to have lunch up there before you head back down again.

    Be sure to wear lots of sunscreen, a loose airy shirt, and a big hat. There is *zero* shade on the way up and I managed to get burned on odd parts of my body.

    It is definitely a good workout, but I’d advise against novices taking it! At the time I had little experience hiking, so for about two days afterward I could barely walk because of the DOMS. But it was still worth seeing all that awesome stuff. 😉 Thanks David, your website is a valuable resource!
