This wasn't a hike, but the family spent the day at the Hyak Sno-Park, which is located right at the Hyak trailhead off the Iron Horse John Wayne Trail. Take I-90 to Snoqualmie Pass, get off at Exit 54, and follow the directions to the Hyak Trailhead.
Today we enjoyed a beautiful, sunny day free of clouds and precipitation. Since it was Dr. Martin Luther King, Jr. day, kids were not in school and it seems like all of Eastern and Central Washington congregated in Snoqualmie Pass.
Nested at the bottom of the East Summit at Snoqualmie, the Hyak Sno-Park has a couple small sledding hills, plus some ad hoc hills suitable for younger (under 5) kids. Not a large area by any means, but loads of fun for the kids. Many people bring their tailgate gear and have a nice picnic or bar-b-que. Very smart idea.
Parking is $10, and in the end it is quite a bargain compared to the $75 we would have forked over at the Tubing Center at the Summit at Snoqualmie.
