Pratt Lake Basin

The path to Pratt Lake was once a braided super highway, at times more than 10 feet wide. Hardly the stuff of wilderness. But Washington Trails Association (WTA) volunteers stepped in and rebuilt the trail. Not only did they rebuild the tread to channel all hikers onto the proper path, they decommissioned all the unauthorized secondary trails, creating a new single track worthy of a pristine wild area. Hikers can now stroll easily up this picturesque trail to the pretty Pratt Lake basin.

The first mile of trail is busy. You're sharing this section with crowds headed for Granite Mountain. But don't worry: at the 1-mile mark most of your fellow hikers will peel off to the right as you push on straight ahead to Pratt Lake.

At around 3 miles out you'll find a fine viewpoint at 3400 feet. Pause to take pictures of the Snoqualmie Valley and the peaks above the Ollalie, Talapus, and Pratt Lake basins. Just beyond you'll enter the Alpine Lakes Wilderness, and then you'll encounter a side trail at 3.8 miles leading down to forest-rimmed Talapus Lake.

A scant 0.25 mile past this junction you'll reach a low saddle (elev. 4100 feet) separating the higher Pratt Lake basin from the Talapus and Olallie basins. This is a great place to stop for a rest and, in late August (most years), to harvest the abundant huckleberries. Turn around here unless you really need to reach the lake.
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.

Trailhead still closed for granite/Pratt lake due to crime scene. Posted notice says Pratt is still open, but granite is closed. It's confusing because they have police tape across the entire trailhead.

Another gorgeous day for a hike! First mile was basically snow free. Second mile had spots of snow but nothing too bad. Third mile had packed, snow covered trail. Last mile became increasingly soft snow so snow shoes would have worked better than my microspikes. Followed the tracks but at around the 4 mile mark, the path started up the mountain. I didn't think that was right, thought I was close to the saddle. Made it up to a spot where I got a great pix of Mt. Rainier and then headed back down. Looking at my GPS route, looks like the worn path gets off trail right toward the end. Had I been able to see the trail I was very close. Oh well, a good excuse to come back and do this hike again.

Attempted to hike Pratt Lake today but there are still snow on the ground. First mile was fine but as we get farther up, there were more snow on the trail making the hike difficult and slippery. We decided to turn back after walking about 2 miles since we didn't have a walk stick and I already fell several times during the trip.
