Grand Prospect from Snoqualmie Point (one-way track)
This is moderate-to-difficult year-round trail to Grand Prospect on Rattlesnake Mountain. This area has recently become very popular with mountain bikers since many trails have been added for their use, but their trails are mainly separate so they do not pose a problem for hikers.
On a clear day you can see Mt Si, but the views on this hike are not exceptional. However, the trail itself is in excellent condition and makes a pretty conditioning hike through the forest.
At the parking area for this hike, there is an outhouse on the left and a large sign on the right. The sign on the right has a map of the hiking trails. The hiking trail can be taken all the way from this point to Rattlesnake Ledge, which is approximately 10 miles as a through-hike. Take the trail to the left of the large sign up the hill. At the top of the hill, you will reach a sign which shows only the mountain biking trails in the area. Continue up the hiking trail (the trail on the right is a biking trail).
During this hike several times, you will cross a gravel road. Simply cross the gravel roads and continue up the hiking trail. At your last gravel road intersection, there will be a sign pointing left to Stan's Overlook, it is about a quarter mile down the road. You can check this viewpoint out, but you will want to take the sign pointing up to Rattlesnake Mountain for your final destination.
Take Exit 27 off of I-90 East and take an immediate right. Head up the hill until you reach two gates. The one to the right leads to a parking area for the trailhead. Parking here requires a Discover Pass.
You can also park outside the gates without a pass alongside the road. This is also a good idea if you plan to do this as an evening hike.
