Near freeway but worth it
This is a great campground on the south fork of the Snoqualmie River, however, no matter what month we go, the water is always super cold. Gotta love glacier water.
There are ton trees through the site as well as more open sites to get the occasional sunshine. We stayed in a site directly on the river and loved hearing the sound of the water at night. There are a few bathrooms around the campgrounds but only one water spicket for drinkable water.
There was both walk-in sites and reservable sites for both tents and RVs. No hookups though.
My littles loved the Discovery Trail on the edge of the campground. It was super easy for them to do and only about a mile and a half.
Off the 90, you have to go down a mile and a half unpaved road. The sight is near the freeway and you will hear the cars during a busy weekend.
