If you ride from downtown Seattle, through here:
over this bridge:
you will suddenly find yourself here, feeling like you are a million miles away from Seattle:
Here is the view, looking back towards downtown:
And if you go just a few more miles you find yourself on the back-side of the peninsula, with no view of the city at all - just islands and mountains and water.
This is a super-quick, short bike ride from downtown, and I had never been there until a few weeks ago (and I have been biking in Seattle for over a decade!) You want to make sure to do it on a weekday though - apparently it becomes quite the place to go "cruising" on weekends in the summer (I didn't know people actually "cruised" anymore, but I guess they do if you are in West Seattle.)
