I grew up in Snoqualmie, you’re talking about all my old haunts! HAHA! I think it was the Burke Gillman Trail that went behind the building where I worked at Union Bay Sportswear in Kent. The trail in Carnation might be a little rough right now with all the flooding.
Snoqualmie is a beautiful area! After the trail went up the hill out of Carnation it became a little rough years ago, but the part of the trail that goes up to Rattlesnake lake was pretty bad in some areas and this was because of water running across the trail in some areas. A lot of the trail has had problems at times. The John Wayne Trail in this area is largely maintained by groups that are mostly made up of horseback riders and they have a different perspective about what type of surface is ideal.
