Alotta folks go shooting east of Granite Falls in a place that used to be an gravel pit. That's where I usually head when I wanna shoot stuff that I can't at an indoor range. (propane tanks, toilets, windows, etc. I'd say it's about a 45 min drive each way from Hwy 9, but I drive alittle fast.
From Hwy 9 take Hwy 92 east to granite falls. Turn left in town by the school, I think it's the second stop sign. That will be mountain loop Hwy. follow that past the entrance to the national forest (near the ranger station on the side of the road).
After you cross a bridge, (i think it's blue) you will find 351st Dr. NE immediately on your left. Instead, turn right up the hill which will become a gravel road quickly. You'll know this is the correct road because as soon as you cross the bridge and turn right you'll see the old road that skirted the east bank of the river has been washed out as the riverbank fell into the river. If you took this road to the top, you'd be a short distance from the inactive ski lodge that used to be up there. some people take there quads, dirtbikes, and offroad machines up there.
Part way up the hill you'll pass a parking lot, and permanent sani-can on your right, and a gate in front of you that's usually open, unless the road ahead is unpassable. Usually this is the part where skiers and hikers leave the road.
Continue up the road in a southwesterly direction. About 4.5 miles from where you turned off the mountain loop hwy the road will switchback to your left, the southeast (not the first switchback though.) Follow the jeep sized trail (though I've done it on my motorcycle and in a fullsize bed king cab 3/4 ton truck as well,) that heads south then turns west, then south again. That total trail length is about 100 yards.
As you round the last corner, you'll enter a big rock bowl on one side with cliffs not far into the woods on the other side. As you'll see from the ground, (if the snow is gone,) hundreds of thousands of rounds have been discharged here and there is plenty of man-made debris that usually gets left up there to shoot as well.
Have fun! Most of the hikers are several miles below you and the offroad types are still a few miles up the road at the summit, so there's not really anything to worry about accidentally shooting

. You can believe the old junkers they find up there wen the clear cut also its a great spot to watch firewoks on the 4th . You can see all the shows from Hood Canal to Tacoma's depending on where your at on Capitol Peak . The last time I was at Granite Falls , I was up there for a FAL shoot a couple of years ago , great place to go .
