  • How may I use the trails?

    All trails in the Arroyo Seco are open to walkers, hikers, or joggers. Equestrians are welcome on most Arroyo Seco trails, although not recommended on the Rose Bowl Loop or Brookside Fitness Trail. Cyclists are welcome on paved roads throughout the Arroyo Seco as indicated on park signage. On-leash dogs can enjoy the trails, too, so bring them along — (just be sure to clean up after your pet.)

    Please remember: the Arroyo Seco is a dynamic system that can change from a trickle to a roaring river in short order and without warning. In the event of rain, please keep away from the streambed and move to high ground.

    Brookside Fitness Trail 

    Located in Brookside Park in the Central Arroyo, the Brookside Park Fitness Trail is a 2/3 mile loop with 14 fitness stations targeting stretching, balancing, coordination and strength building exercises.

    Rose Bowl Loop

    The most popular trail in the Arroyo Seco, the Rose Bowl Loop offers walkers, joggers, and cyclists a great place to exercise with spectacular views around the Central Arroyo. The Rose Bowl Loop is 3.3 miles long and circles Rose Bowl Stadium and the fairways of Brookside Golf Course. The route is distinguished by colored pavement; striping and delineators help separate pedestrians from cyclists and motorists.

    Please be courteous and cautious as this is also a public road open to vehicular traffic. If you’re in the designated pedestrian lane, please walk counterclockwise to be safe!

    In the north end of Hahamongna Watershed Park, the Arroyo Seco Trail connects to the Gabrielino Trail and the Altadena Crest Trail. Near Flint Wash Bridge, trail users can connect to Flint Canyon Trail.

    On the western side of the Central Arroyo in Salvia Canyon, the John Crowley Trail connects the Linda Vista neighborhood with the Arroyo along a trail recently restored with native vegetation.

    The neighborhood trail running along Arroyo Boulevard on the east side of the Lower Arroyo provides multiple access points for reaching the Arroyo Seco Trail.
