How to get to D.C.H.S. from Pacific Crest Trail

I've been noticing some trip reports here recently about how very high the river is right now, and how therefore very dangerous the crossing is.

I know how to get to D.C.H.S from the Bowen Ranch side. If I wanted to get there from the Pacific Crest Trail side (so, be able to skip the river crossing altogether), what would be the best (and shortest day-hike) way to do that? Where would I park (googlemaps link?), keeping in mind that I drive a regular sedan, so I can't do anything too rugged off-roady with my car. Something like the drive up Bowen Ranch Road is fine. Something where a high-clearance vehicle is clearly required, not so much.

Does such day-hiking access exist from the Pacific Crest Trail side?

Thanks!
