The Echo Mountain hike packs a lot of bang for the buck. You’ll hike up the Sam Merrill Trail, which follows the old Mt Lowe railway route up to Echo Mountain, where you can see the old ruins of the Echo Mountain mountain resort. USA Today included the Echo Mountain hike as one of the “10 Great North American Hikes” and Sunset Magazine called it one of the top 45 hikes in the west. The hike is easy to follow, has an interesting history, offers great views, is a good workout, and is close to LA. Overall it’s a win.

These directions have an optional hike extension to a scenic viewpoint at Inspiration Point. See directions for more info.

Echo Mountain Hike Mt Lowe Railway
The hike will parallel some of the old Mount Lowe Railway route. Here you can see the electric trolley filled with tourists climbing to Echo Mountain. This hike has an interesting history.

The Sam Merrill trail to Echo Mountain starts at the 1070-acre Cobb Estate, which is now public parkland, but was originally built by lumber magnate Charles Cobb. He passed away in 1939, and it became a retreat for nuns for a few years, and then the Marx Brothers bought it in 1956. They realized the property was not usable and had the structure torn down in 1959. In 1971 an anonymous donor purchased the property and gave it to Pasadena to turn into a park. And it’s allegedly haunted, so there’s that.

As you climb the trail, your route will parallel some of the old Mount Lowe Railway route, which was the only electric mountain railway ever built in the USA. At the time it was built in 1893, it was considered a modern marvel and had over 3 million visitors during its lifetime.

Echo Mountain House
The Mount Lowe Railway led to the Echo Mountain House, which was a 70 room Victorian hotel built to rival the Hotel del Coronado in San Diego. It was intended to be a full service resort “a mile up in the sky.”

The railroad lead to the Echo Mountain House Resort (cool old pictures here), which you can see the ruins of at the summit of the Echo Mountain hike. There was a hotel, restaurants, tavern, observatory, million candlepower searchlight, and the famous echo-phones which you can still use today.

The resort and railway weathered some fires and natural disasters over the years, but the great flood of 1938 (the same one that created the Bridge to Nowhere) was the final nail in the coffin, washing much of the railway and resort away. From there, Sam Merrill, who lived with John Muir as a young man and was active in the Sierra Club, restored and maintained the trails to Echo Mountain. When he died in 1948, the Sierra Club named the trail after him.

Where is the Echo Mountain Hike?

Use this as the trailhead GPS address: 3302 Lake Ave, Altadena, CA, 91001, USA.

Parking is free on residential streets around the trailhead. It’s a popular hike so you might have to park a few blocks away.

Gear for the Hike

This is a bit of an in-between hike. You can certainly do this with fitness clothes and minimal gear, but I do recommend hiking gear if you have it. The Echo Mountain hike is a steady uphill, so prepare for the effort. If you’re going to do the extra loop to Inspiration Point, definitely use hiking gear.

Here’s the gear that I personally use, have tested, and recommend for this hike*.

Osprey Talon

Osprey Talon 33

My best lightweight pack for hikes between 3-10+ hours. I use mine with the 3L water bladder from Osprey.

Topo Maps & Guide Books

Don’t be caught out if your batteries die. Take a topo map with you on the trail. Some people also print my guides out for use on the hike.

I also highly recommend taking a map and compass navigation course. It’s a few hours, it’s fun, and it could save your life.

Turn by Turn Directions

cobb estate sign
Go though the Cobb Estate gate and start walking. There’s a sign for the Sam Merrill Trail, which is what you’re going to take.
trail on echo mountain hike
The beginning of the hike is probably the hardest to follow, with some weird twists, turns, and junctions. To start, just head up the old road.

In a minute after that, you come to a big intersection. Make the hard left at the very edge of the ravine.

You’ll hike above a dry river bed. Stay on this short section of trail as it goes past a dam in the riverbed to the right.
trail on echo mountain hike
The trail dips down across the dry riverbed. Avoid side trails and go across to continue on the trail.
trail on echo mountain hike
The confusing part is almost over. Avoid any side trails and stay on the main trail. If a trail fizzles out, you probably made a wrong turn and ended up in a place where teens drink beer. Turn around and head back if that’s the case.

The trail become simpler and winds it’s way up switchbacks toward Echo Mountain. It’s steep. Take time to catch your breath and enjoy the view.

I stopped for a selfie but really I was tired. You can see the trail below. Keep on climbing.

One of the cool things about this hike is all the informational plaques. You’ll see the ruins of the old resort, and usually there’s a sign explaining what used to be there.

There’s lot’s of ruins and hiker-made art to see when you explore here.
echo phone on echo mountain
At the back of the resort area, you’ll find the echo phone. You can allegedly yell into this and they’ll hear you at Inspiration Point (see below). There’s also an echo off the mountain. It’s obnoxious but all part of the fun.

Get your selfies and head back down the way you came to finish the hike. If you have the energy, I’d recommend continuing your hike up to Inspiration Point.

Optional Loop to Inspiration Point

trail on echo mountain hike
Head back out the way you came. If you want to finish, go straight back the way you came. For Inspiration Point, look out for the first trail on your right.
trail on echo mountain hike
The Castle Canyon trail to Inspiration Point is to your right. It’s smaller and overgrown, so keep your eyes open. It comes a minute or two after leaving the resort ruins area.
trail on echo mountain hike
There’s an old stone plaque just past the trail. Make sure the sign says Castle Canyon. The next trail to the right is identical, so check the trail name.

The Castle Canyon trail is smaller and lacks the crowds of the Echo Mountain hike.

After a few minutes, the trail follows the left side of a canyon. It’s really scenic.

Turn back for some great views of downtown LA.

The trail gets thin at some points. Take it easy and watch your step.

It gets steeper as you get closer to the top. Baby steps…

At around 4.9 miles, you’ll start to see the Inspiration Point pavilion. Almost there!

You made it! You will reach Inspiration Point in a little over 5 miles.

One of the neatest things here are the viewing tubes. Each tube is pre-set with the right direction to look for the respective sights. Keep an eye open for the viewing tube for Inspiration Point – it’s pretty funny.
inspiration point on echo mountain hike
The pavilion is pretty cool, with awesome views. Opposite the pavilion are view of Mt Wilson, which is also a great hike (see end of article).

When you’re done soaking it all in, head straight down the road (left if you’re looking at the trail from inside the pavilion). There’s a sign pointing you in this direction for the Sam Merrill trail too.

The trail is pretty wide here. Continue straight to start your well-earned downhill.

At about 0.3 miles from the pavilion, you’ll reach a junction. Make the hard left onto the Sam Merrill trail. You won’t be able to see it easily as you approach.
trail sign on echo mountain hike
Here’s the sign marking the beginning of the trail.

While you could have retraced your steps from the pavilion at Inspiration Point, this route has a much more scenic descent, but the trail is a little more primitive.
sunset point sign
Take a break at Sunset Point for some great photos of LA, Catalina, and the surrounding mountains.

At around 6.5 miles in, there’s a split in the trail. Head left. If you want a quick detour with views, go to the right on the ridge. A lone pine tree marks a great vista point. Head back after checking it out.

As you descend, you’ll see the Sam Merrill Trail unravel beneath you. If you look closely, you’ll also be able to see the ruins of the resort.

Shortly before you arrive back at the resort ruins, you’ll see some more ruins including an old fireplace.
