Riding over to Alki beach is also a nice ride. You can also head out east over the I90 bridge bike/walk path. You can drive down to the south center area to park then ride the green river trial. there is also the interurban trail down there but its fairly boring but runs north from Renton south to Pacific. I take the interurban south then ride through Sumner to connect with the Pioneer trail in Puyallup and hit up the Orting Bakery for a mid ride snack. You can go to the king county website click under transportation and find all the bike lanes and bike trails on King County. It's more up to date then Google maps.
