Nhk750,
I might never get up to Lake Washington, but just in case I do, where is the best place to put in? Is the parking secure?
Since I would be coming from the south, I guess I would be more interested in something near Renton. I've been on Lake Washington, but it's been a long time and it was in a sail boat. We used to come in through the ship canal to see the hydro races.
I park at Gene Coulon park. It is at the very South end of the lake and has great secure easy parking close to the water. you have to be out of the park by 8pm though. This is in Renton right next to I-405 and is patrolled regularly by the Renton police. I have never had a problem there.
