Waterfalls cover the Cascade Mountains. Spring and summer there a many, late summer and fall, less water. In early spring we can't get to one because of the snow plowed blockage; in the fall it is a wonderful stop. The Pacific Northwest Cascade Mountains feature impressive scenery with mountains, waterfalls, forest, meadows, and white-water rivers. This memorable day trip from Seattle crosses over 3 mountain passes, with a waterfall stop on Snoqualmie Pass and a waterfall stop and trail walk on Stevens Pass. If you love the trails, we will spend more time in the mountains, and shorten the lunch stop.
