The Arroyo Seco Natural Park is the City’s largest natural open space with 22 miles of trails and myriad recreational opportunities. It is a passageway for both wildlife and people, linking its trails to those of the Angeles National Forest and the Rim of the Valley trail system. This network of trails provides opportunities for short leisurely strolls or day long adventures, just minutes from bustling metropolitan areas.
In addition to the miles of trails, the Arroyo Seco Natural Park offers a variety of recreational facilities: playgrounds, multipurpose fields, specialty sport fields, an aquatics center, a museum, a golf course, a world class sports stadium, and more!
In the 900 acres of the Arroyo Seco Natural Park one can golf, swim, run, walk, jog, bike, picnic, bird-watch, play ball, fly a kite, play disc golf, flycast, shoot a bow, watch a world class football game at the Rose Bowl, and more. Click on the links below to learn more about the facilities.
Information on facility reservations is available through the City of Pasadena’s Human Services and Recreation Department.

The Arroyo Seco is a dynamic landscape providing visitors the thrill of experiencing a living environment. As is typical of a natural setting, conditions in the Arroyo Seco can be undpredictable. It is important to be familiar with the potential dangers. Avoid approaching, feeding, or touching animals. Be aware of mountain lions and rattlesnakes. Avoid contact with poison oak.
Trails in the Arroyo Seco are open from sunrise to sunset, 365 days a year. 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 along Fido—(just be sure to clean up after your pet.) Stay on the trails and remember to share the trail with other users.

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.
