Denny Creek is a very unusual yet very nice campground. It has 11 electrical sites, which is unusual in Washington for a Forest Service campground. There are three hikes that start at the campground and several more just a few miles away. Snoqualmie Pass, with a hotel, restaurant, gas station and small store is only three miles away. The campground is set in the tall timber with very good privacy between the sites. The one drawback, which is the other unusual fact about the campground, is that it is in the middle of I-90. The eastbound lanes are about 500 feet above the campground and the westbound lanes are across the river again about 500 feet up. You can't see the traffic but you do hear it. Not bad but constant. If you have a site on the river, the sounds of the river may drown out all but the loudest vehicles. There is no dump station on site. The campground is very well maintained and would have been the perfect "10" with the natural beauty and recreational activities it offers but for the traffic noise. We camped here in a Travel Trailer.
