I love hiking this trail. You get a great workout and at the top of Echo mountain, you get a history lesson on the great hostel that was once there! I wish it was still there, it would've been a great place to stay!

We are fortunate to live close to this trailhead, which takes hikers to the historic ruins of an old hotel at Echo Mountain and remains of the Mt. Lowe Railway. Yes, you should be a hiker in fairly good shape (it's just shy of 3...More
