Trail along the Arroyo Seco streambed

Outdoor Activities

Arroyo Seco

The seasonal canyon that runs the length of west Pasadena, with trails from Hahamongna to the Lower Arroyo.

Why visit

The city's defining landscape feature and its longest continuous trail system, passing under the Colorado Street Bridge.

The arroyo runs from the San Gabriel Mountains through Pasadena toward the Los Angeles River.

Lower Arroyo Park, Brookside Park and Hahamongna Watershed Park form a nearly continuous open-space corridor.

Know before you go

  • Trail surfaces are unpaved in the Lower Arroyo.
  • The Colorado Street Bridge is best seen from the canyon floor.
