(Lurker status...OFF!)

I'm a very new rider myself, and the Green River Trail was my first ride longer than 20 miles, just about a month ago...I really liked it a lot! Compared to the BG Trail, it was practically deserted. I mean, there were plenty of people out enjoying the sunny Saturday, but nowhere near the crowding of the Burke Gilman. I'd only planned to go south halfway or so and turn around, but I was enjoying the river trail so much I went all the way to the intersection with the Interurban for about a 38-mile round trip from my house in Rainier Beach. It's a nice flat ride by the river with quite a few parks along the way...I definitely took my time enjoying the scenery, and will definitely be taking that trail again.

And just this morning on another forum I found a list of southern King County routes that I bookmarked...maybe that will be as useful for you as I hope it will be for me.

Have fun!
