Ft Casey is about 10 miles north of Bush Point off Highway 20 on the west side of Whidbey. Access is through a State Park. Fish it the same way as Bush, as outlined in the news (spin & glow and hoochie, slow retrieved). Peruse the threads over the past month, I recall seeing one about steelhead in the salt.

I've fished both areas for silvers, not steelhead, but Bush tends to have gentle rollers lapping the beach while Ft. Casey can have some 4 footers with strong tidal currents. When fishing silvers, if the fish were not in strong, Casey seemed to be better; the strong currents probably concentrated the fish. When the silvers were thick, it was hard to beat Bush. As with silvers, I hear that the steelhead cruise pretty close to shore (stay out of the water; no need to cast a mile) and the best fishing is on either side of high tide.

If you go, post a report. Good Luck!
