Cascade Valley is located in the North Cascades National Park. It is divided up into three Diffrent forks as you go farther east, the North, the Middle, and the South fork. This is among a great set of Cascade Peaks, which is why it is my favorite valley. It is most commonly entered through the West side from Marablemount, which a road goes through most of the Cascade Valley, but not through the middle and South Fork. It can some times be closed through out the winter months, and Early spring, and depending on the snow pack or if there was a wash out, it can even be closed 3 miles from the trailhead the enture year, but is often opened by August through October, and some times open June and July.
North Fork: The North Fork is the most commonly the most populated in summer, due to Cascade Pass, which is a great day hike and is only 3.9 miles to get to. And of coarse for those who want more, theres Sahale Arm and Sahale Mountain. Also theres Bosten Basin and Hidden Lake Peaks which are also Classic North Cascade hikes, and for those who are more into climbing, there's Eldorado Peak, Bosten Peak, Mount Torrment, and Forbidden Peak.
Middle Fork: The middle Fork of the Cascade Valley is said to have an old trail that goes through part of it, which goes to Mount Formidible. This Mountain can also be accessed through the Ptarmigan Traverese, which is a multi day back pack trip through non trail terrain, and if I'm not mistaken, I believe it is techincle.
South Fork: The South Fork which I believe theres no trail, and is a long trek, goes to South Cascade Lake, which near it is South Cascade Glacier, which is unfortunatly melting away due to Global Warming. Also Dome Peak is a part of this section of the Valley
