This isn't a hike, except that it's very close to the Rattlesnake Mountain Trailhead. But the new Snoqualmie Point Park provides an amazing lookout over the Snoqualmie Valley.
I first came to this location a couple years ago when I heard of the "Old Snoqualmie Winery." At that time it was a cool viewpoint of the Snoqualmie Valley located right off I-90 Exit 27. My understanding was that a large winery existed here at one time but burned down in 1999 and other than clearing out the old buildings, nothing had been done with the land since. Last year when we came up we noticed a ton of construction activity. Today, we took a look and much has been completed although it doesn't look like the park is officially open yet. It has parking, lots of stone landscaping, and a pavilion with amazing views of Mount Si, Teneriffe, Rattlesnake Mountain, Mount Washington, and Snoqualmie Valley. We even caught a great glimpse of Mount Baker today.
I took some pics, but they just don't do the viewpoint justice.
