Wildwood Regional Park is an incredible park with several trails. The address is 928 W Avenida De Los Arboles, Thousand Oaks. I did a quick mile loop one morning before work and had a wonderful time. There is also a good 3-mile loop in this park and you can see some photos (I was still experimenting with HDR at the time, so some are a bit too saturated) from that hike here:

with lovely plants and cactai.
I didn't take this trail, but it leads to the tee-pee and downhill to Paradise falls.
This was my favorite view of the morning. I loved the way the hills were silhouetted by the fog and light.
The trail starts to decend into the canyon:
And back up the canyon with lovely bouts of cactai:
A stunning panoramic view:
And some beautiful scenes at the end of the trail:
