Echo Mountain Via Sam Merrill Trail

The Sam Merrill Trail to Echo Mountain is one of Altadena’s most iconic hikes. Beginning at the Cobb Estate off Lake Avenue, this moderately strenuous trail climbs steadily through chaparral-covered slopes to the ruins of the historic Echo Mountain resort. Along the way, hikers are treated to panoramic views of Pasadena, downtown Los Angeles, and, on clear days, even the Pacific Ocean. This out-and-back trek is popular for sunrise and sunset hikes, thanks to its dramatic vistas and well-defined path.

For those interested in history and photography, the crumbling foundations and old railway remnants at the top offer a fascinating glimpse into Altadena’s past. Because of its popularity, it is best to start early in the morning or later in the afternoon to avoid mid-day heat and crowds.

Eaton Canyon Falls Trail

Another favorite, especially for families and beginners, is the Eaton Canyon Falls Trail. This relatively easy route follows Eaton Wash through a picturesque canyon, featuring native plants, birdlife, and seasonal wildflowers. The reward is a small but beautiful waterfall tucked at the canyon’s end, making it an ideal destination hike on warmer days.

The trail begins at the Eaton Canyon Natural Area, which has educational displays and ranger-led programs that enhance your understanding of the local ecosystem. While water flow varies by season, the shaded canyon and multiple stream crossings create a refreshing atmosphere year-round.
