One look at the parking lot midday on any summer weekend, and the obvious will jump out and bite you: the Granite Mountain Trail is the most heavily traveled summit path in the Snoqualmie Pass corridor. Of course, there is a good reason for that: it's spectacular. But it's also steep. Mind numbingly, thigh-burning steep. You'll climb a heel-blistering 3800 feet in 4.3 miles to an old fire lookout at the 5600-foot summit, with awesome views in all directions. Pack plenty of water, as there is no good source along the trail.
The trail starts out climbing. You'll hike away from the trailhead parking area through a lush old forest and gain a solid 800 feet in the first mile. At 1 mile the trail forks. Turn right off this relatively flat trail for some serious climbing (to Pratt Lake goes left). In the next 0.5 mile the switchbacks are easy, if a bit steeper. But as you near 2 miles the switchbacks get tighter, the trail gets steeper, and the breathing gets more difficult. At 4000 feet elevation you'll get a breather as the trail angles across a tricky avalanche chute. Caution: Early in the year the upper mountain is covered in snow and ice, and the upper slopes are VERY avalanche prone. If you're here any time before mid-June (most years), pause before crossing the chute and look up the gully. If there is still snow above you, be extremely careful--slides can happen at any time. Once across, the trail starts climbing again. If you time your trek just right, you'll find huckleberries alongside the trail all the way to the ridge top. You'll also break out of the trees and start exploring wide, steeply slanted meadows. Bulbous beargrass fills these meadows in early summer, and when those white blooms disappear, lupine and paintbrush color the slopes red and blue. At 5200 feet you'll crest the summit ridge, getting a brief reprieve from the ruthless climbing as you cross a meadow. You still have another 0.5 mile or so to cover along the ridge crest and then up the summit crown, but the hardest work is behind you. Get to the top and enjoy the 360-degree views from the lookout--on some weekends, volunteers open it up to visitors.
Driving Directions:
From Seattle drive east on I-90 to exit 47 (Asahel Curtis/Denny Creek). Turn north over the freeway, turn left at the T, and drive to the nearby Pratt Lake-Granite Mountain parking area. Recent Trip Reports

started the trek about 2pm. parking lot had few cars, but plenty of open spaces. hit the trail and up we went. for those who are unfamiliar with this hike, the grade is comparable to mount si, but with half of the hike in open area, rather than all of it in the trees. the avalanche chute was no problem, as it is cleared out and the trail continues thru. about 2.75 miles into the hike, a few snow patches needed to be crossed. at mile 3, you either have to start walking in the snow, or just walking along side of it up to the scramble area of boulders. we stopped at the boulders due to the fact ton of snow remained up to the lookout, and we did not have any gear for stabilizing ourselves on the narrow ridge to it. so we had some grub and back down we went. took about 2 hours to get up and about 1.25 to get back down. overall id wait it out a few more weeks and hope the snow clears. it was little icy and slick, but if you wanna make the effort its also do-able, we just choose to say screw it.

The Cap'n and I had never been up before, didn't quite make it this time. Very late start after a very late night out. The trail isn't really all that steep compared to the many steep trails we've done now, like Old Si, but it's consistently steep-ish for 3 whole miles, which is kind of draining in hot, muggy weather. Had to rest a lot, drank tons of water. Pretty views out across the valley.
Shortly after the lookout finally came into view and we hit the first snow patches, storm clouds blew in, one after another, with a little rain here and there. We repeatedly questioned whether we should keep going, especially after hearing a few peals of thunder from across the valley. We were swallowed by clouds occasionally from this point on. Cut around a few of the snow patches on a dirt track on the valley side. Strapped on microspikes for the steep stuff. At about 300 feet of elevation below the top, the boot track followed the now continuous snow up along the ridge line adjacent to the boulder fields. Snow sloped deeply toward a bowl to the right with water running out from under, not something I'd trust to be safe. I understand that the summer trail goes that way, but there are no tracks there whatsoever, so I don't think it's okay until it totally melts out, though I really have no idea. We soon started crossing one extremely dubious snow bridge after another between/next to the boulders. When I realized how bad they were, I started hyperventilating as I crossed. There was sort of a trail through the boulders here and there, but it looked like staying off the snow would involve extensive boulder scrambling, and by now, it was getting late, and we were kind of tired for that sort of strenuous travel. We saw plenty of other people had come up and down, including a featherweight trail runner that passed us, but I also could see where poles had punched through the voids. Since the Cap'n is truly a giant Viking, both extremely tall and built quite large, we decided that the double dangers of possible lightning strike + chance of a much heavier than average hiker punching through dubious snow bridge and breaking leg(s) resulting in a $4000 SAR rescue = time to turn around and return another day. Excruciating decision, as the lookout was was literally something like 800 feet of distance up the hill in front of us, but a relief to not constantly worry about injury or death. We'll be back later, after the bad snow bridges melt out and we haven't been out partying all night beforehand. If you go, would advise you to be very cautious on the snow along that ridgeline.

I started around 5pm to take picture of the sunset from the fork. The trail is in excellent condition before the last 0.5 mile. The last 0.5 mile are mostly under snow, but it is manageable. Just follow the footprint carefully and you can reach the peak. Be very careful for the soft snow near the rocks.

The trail from the parking lot to the turnoff to Granite Mountain was a little soggy, but no actual issues involving mud- so it is in excellent condition.
The switchbacks up from there were quite clear and yielded some new views that have appeared since my last trip up there (avalanche debris field gives a good clue as to how it got cleared) However there are no blow-downs blocking the trail at all! At 4,400ft... the snow starts fairly abruptly with a decent snow field. You can skirt the field to the right on some boulders but any approach on the snow should be done with snow travel skills and the proper gear. The actual approach to the lookout is a mixed bags of boulder hopping and careful snow travel. Due to the time and safety concerns- we just went to a decent panorama spot and called it good. The spine to the lookout has some fresh avalanche scars in it- so be careful and don't be afraid to turn back :) Day hike

Despite the clouds and rainy forecast today was a great day for a climb up Granite Mountain. The trail toward the summit route is in fine shape, no blowdowns or other obstructions. There are a pair of avalanche gullies that require short snow crossings, but are hardly of note. Further up however the snow starts to take up the trail and the beaten path abrptly ends at one last island of bear grass and trees. This is the point that you have to start heading up the snow covered mountainside, you're going to wish you brought boots and gaiters at the least. Heading off in a westerly and up sort of direction the fire lookout eventually came into view between the clouds. The path to the summit is still on decent snow, though there were a couple of deep postholing incidents. Towards the summit we were greeted with a light snowfall, which was unexpected, but welcome, like Christmas in May! Lots of great glissading opportunities on the way down, so much so by the time we got back on the trail my rear end felt like it'd been dragged across cold, wet sandpaper. In summary, be prepared for lots of snow travel, some of it fairly steep.
