Hiking to Storm Pass via the Mill Castle Trail is otherworldly. The view of the Castles is dauntingly beautiful. This hike in the autumn is pristine though be wary that there is some elevation re-gain on the way back.

Amazing views, great fall color! Didn't hike the whole thing, just wanted an afternoon hike so I went up to the first ridge--where you pop up over the valley you've been hiking in until then.

Tough as it gets steep. Beautiful in fall.

How was it you might ask? It is an amazing day hike for any one. You can hike to a meadow, and turn around or hike till the trail ends. Both choices are perfect for this hike, and no matter your means of transportation you won't miss the view.

Mill Castle is a steep trail, I suggest going in from the south, and up to Storm Pass. The Views from Storm Pass are excellent, North and South. The Northern end of the trail was full of cattle grazing, with a lot of manure to avoid at lower elevations. We saw a herd of 100+ elk just south/west of Storm Pass, and several mule deer.
