  • Things to See & Do in the Arroyo Seco

    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!

  • Playing it Safe

    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.

    • Tell someone where you plan to be in the Arroyo.
    • Carry enough water to keep you hydrated during the time of your visit.
    • Wear sturdy shoes, sunscreen, a hat, and helmet (if you are riding horses or bikes.)
    • From fall through spring, be sure to wear layers as weather conditions can change unexpectedly.
    • Be respectful of all plants, animals, and people you encounter within the Arroyo
