The Mountain Loop Highway is home to many popular cascade hikes and climbs. There is no doubt that the scenic beauty of the Mountain Loop Highway Peaks far exceeds that of the I-90 corridor Peaks. There is more diversity in wildlife, foliage, and summit blocks are generally more rugged and exposed. The Mountain Loop Highway is a well kept secret among the locals of Washington State with the exception of Mount Pilchuck, trails are seldom crowded and tranquil isolation is the norm.

If you are at all fascinated by the history of the Monte Cristo area, you need to see the tunnels of the Monte Cristo Railroad near Granite Falls. The railroad tunnels were constructed in 1892 as part of the rail line between Everett and Monte Cristo. In Robe Canyon, they constructed three bridges and six tunnels. Shortly after, a storm washed out the grade and buried parts of it in landslides. The river would even travel through the tunnels washing everything away. After this happened a few times, they decided to embed the rail ties in concrete, including through tunnel #6.

The Mountain Loop Highway is a scenic byway in the U.S. state of Washington. It traverses the western section of the Cascade Range within Snohomish County. The name suggests it forms a full loop, but it only is a small portion of a loop, which is completed using State Routes 92, 9, and 530. Part of the highway is also a designated and signed Forest Highway, and is known as Forest Route 20.
