I love the Chief Sealth Trail. I'm not sure why ... it'd be very scenic if not for the buzzing power lines, and it doesn't really fit in with the neighborhood and the roads you have to cross ( other than Orcas ). Honestly, the reason I like it is probably that I'm always buzzing with endorphins from climbing since Seward Park, when I get to the trail. But Chief Sealth is fun, albeit paved.
I can't think of too many gravel trails in Seattle. There's a short section in Gas Works that's hardly worth mentioning, and a lot of dirt in Ravenna and Interlaken ... although Interlaken is officially not a bike trail. There's a great CX trail in Juanita, which can be reached from the Burke Gilman, but then dirt isn't the same thing as gravel.
The Iron Horse Trail is pretty wonderful, and covered mostly in gravel, but you need a car to get there.

Possibly. You should shoot me a PM when you find something worth checking out.
