The South Pas Nature Park (officially The South Pasadena Arroyo Seco Woodland and Wildlife Park) is a small parcel along the Arroyo Seco graced with mature coast live oaks, southern walnuts and western sycamores. Planted with sage, buckwheat and other native coastal sage scrub plants the park provides an inviting environment for birds, lizards, squirrels and numerous other critters. Locals too enjoy walking, jogging and horseback riding through the park.

Volunteer at the Park

In 2006 the Friends of the Nature Park was created as a community stewardship group for the park. Join us on Saturdays (usually the third Saturday of the month – with no cleanups in July, August and December – at the South Pas Nature Park on Pasadena Ave. to plant, remove weeds and litter, build paths, and enjoy the park. Come for the whole time, for an hour, or just stop by to say hello!

Where100 block of Pasadena Avenue in So Pas, east of York Street Bridge
When: Usually 3rd Saturday of the month, 9 am – noon (no cleanups in July, August and December)

Nature Park volunteers should: 

  • Bring and wear a face mask – covering both mouth and nose
  • Wear sunscreen, hat, sunglasses
  • Bring plenty of water
  • Bring gardening gloves and tools (weeders, trowels, whatever you use in your own garden), there are extra tools and gloves for those who need them
  • Wear comfortable work clothes, including work shoes (sneakers or boots) and long pants
  • Bring binoculars for birdwatching (optional)

Children must be under adult supervision at all times. There is poison oak in the park that we will point out before starting. Also, if you are expecting a group of 10 or more, please email me so that we can have enough tools.

The South Pas Nature Park is a 4-acre habitat park along the Arroyo Seco. The entrance, marked by a small plaque on an attractive river rock wall, is in the 100 block of Pasadena Avenue in South Pasadena, east of the York Street Bridge. There is plenty of on-street parking on Pasadena Avenue.
