The trailhead is somewhat 'interesting' to get to given the dirt roads are in questionable shape and some of the roads in Angelus Oaks are not easily identifiable but I didn't have any problems finding it by closely following Google Maps.    Trailhead parking requires an Adventure Pass parking permit.  Also, as of this writing, permits are NOT required for day hikes, however I was told that this may change so contact the Mill Creek Ranger Station at (909) 382-2882 to get the latest information.  Permits ARE required however for overnight camping.

The first 3 miles are up a series of switchbacks through the forest.  Views begin to open up west towards the inland empire and Mt San Antonio (aka Mt Baldy) in the distance.  The trail then levels off through a mile-long section called Manzanita Flats.  Here some incredible views of your destination open up.  The final 4 mile leg starts back up another series switchbacks.  You'll pass the Limber Pines campground area which could make for a great spot to camp if doing this as a backpacking trip.  As you ascend the final few miles, the views keep getting better, with Big Bear Lake to the north, and the entire inland empire and greater LA basin to the south and west.  About 3/4 of a mile before the summit, you'll pass by a "monument" called Washington's Monument which is a pile of rocks with a placard noting it's name and purpose (in 1852, Col Henry Washington and a US Army survey party erected this monument for the purpose of establishing it as the east-west reference point from which all future land surveys of Southern California were taken).  Finally, you'll reach the summit and take in even more spectacular views, including San Gorgonio (only a mere 5 miles away) and San Jacinto to the east.  Congratulate yourself on having reached the summit of 10,649', and having climbed 4,775' vertical.  To return, simply retrace your steps.  Be careful as the rocks you didn't mind on the ascent now suddenly are something to be wary of!
