This is a steep bushwack to this viewpoint without an official trail. I've shared my trek in the website link from Gaia, although all routes go up and I think I've hiked about 8 different ways to this viewpoint. I prefer this trek as it avoids a lot of downed trees, and takes you up the back side, which is less steep than through the meadow below.
Although this is a favorite for fall, early summer usually has Lupines at the overlook. Be warned - it is overgrown and buggy come spring. I'm happy I have the photo, but not I necessarily want to repeat if you get me.
Dog friendly, however this trail is very steep with a lot of bushwacking. Not ideal for dogs unless you don't have a choice.
