Medea Creek Natural Park in Oak Park
/Medea Creek Natural Park has hiking, biking and fitness trails that stretch from Calle Rio Vista and Oaks Hills Drive in Oak Park on the north, then south past Medea Creek Lane and Conifer Street to a cul de sac entrance to the park at the west terminus of Tamarind Street.
The paved Medea Creek Trail, great for walks as well as casual bicycling, has a northern entry point at Kanan Road across from Deerhill Road (adjacent to the Oak Park Library). It crosses Sunnycrest Drive, where there is street parking, so you do need to be careful with kids when you cross.
The nature loop trail is about 1.5 miles. You will likely see ducks and perhaps other birds enjoying the creek as you choose between the paved and dirt paths. There's also a fitness circuit. It is kind of interesting as you'll see multiple layers of trails; some dirt, some paved, some grassy, some in the creek.
Medea Creek Natural Park is managed by the Rancho Simi Recreation and Park District www.rsrpd.org/business_detail_T9_R29.php
