When going down willow creek road from the 528/ willow creek road/ Idalia intersection, the entrance is a dirt road on the left, after the third street. There's no "willow creek trailhead" sign so finding it can be difficult. There is a small open space sign but that's about it until you get to the trailhead. The dirt road immediately turns right, kinda along willow creek road for a bit until it turns sharp left towards the parking lot. You'll pass a great smell (sewage treatment facility which thankfully the smell doesn't reach far) as you enter the main parking area down the small hill.
take 528 to willow creek. turn onto willow creek and the entrance is the 4th left turn from the intersection
