Hike Sourdough Mountain

9.1 Miles Round Trip - 5104 ft gain - Out-and-Back Trail

503 Diablo Street - Search Nearby - Added by Michael Fricke

This is a tough hike with great views once above tree line.

Going east from Newhalem on highway 20, turn off towards the small town of Diablo. There are signs from there on where to park.

This hike is very difficult. It is very steep and gains elevation very quickly and right from the start. Once you get above tree line though you are greeted with great views of the North Cascades.

This hike is only accessible in July, August, and September usually. Be very mindful of trail conditions. Snow persists in the high elevations in the North Cascades almost year round.
