Where is the Echo Mountain Hike?

Getting to the trailhead for the hike is easy. You just park on a city street in Altadena. Use this trailhead address: 3302 Lake Ave, Altadena, CA, 91001, USA.

Echo Mountain Hike Directions Update 3 — Park along the street leading up to the trailhead, which is at the turn at the end of the street. It can get crowded, so you may have to park a few blocks away. Street parking is free.

This is a residential neighborhood. Please don't block driveways, avoid no-parking zones, keep the noise down, and don't leave trash behind.

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.

Bring 1L of water.
Most of the trail is exposed, prepare for intense sun.
If you use trekking poles and they help, bring them along.

Hike History

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.

The Sam Merrill Trail to Echo Mountain starts at historic Cobb Estate, now public parkland, but was originally built by lumber magnate Charles Cobb. After he passed away in 1939, it became a retreat for nuns, and then the Marx Brothers bought it in 1956. In 1971 local conservationists raised the $175,000 to purchase it, and then donated it as parkland. 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, the only electric mountain railway ever built in the USA. When it was built in 1893, it was considered a modern marvel and welcomed over 3 million riders during its lifetime.

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." At the end of the hike you'll see the remains of the resort.

The resort and railway weathered some fires and natural disasters over the years, but the great flood of 1938 was the final nail in the coffin, washing much of the railway and resort away. After that, 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.
