We got to the trailhead around 10. There was one or two spots left in the main parking area. No toilet paper in the outhouse!
The trail was lovely, with some mud that didn't get in the way. Lots of trillium and yellow violets. The river is gorgeous and green. We followed a little side trail at about two miles in and found a good lunch spot with leftover boardwalk materials to sit on.
One mosquito bite!

Arrived at the Middle Fork trailhead at 8:15 with one other car there. The Middle Fork trail was in great condition with just a few muddy spots. Took the boot trail at Cripple Creek up to Tin Cup Joe Falls. Trail to the lower falls was in great condition. Pretty easy to follow all the way up to the lower falls. There were a few obstacles but nothing major for a seasoned hiker. From the lower falls I took the boot trail to the right and up and above the lower falls to a view of the upper falls where it stops at some thick vegetation. Whacked through the brush to the creek and the base of the upper falls. It was a really beautiful spot. Noticed you could cross the creek below the segment on the left and continue up, but I chose to save that for a return trip. I hiked back down to the bridge over Cripple Creek. On the way down I did lose the trail twice but quickly regained it. From the bridge I headed towards the Dingford Creek Trailhead. This part of the Middle Fork trail was very easy and pleasant. From the trailhead I hung a right on the gated middle fork road for a quick easy stroll to Dingford Creek Falls where I powered up for the 6 mile return trip. The way back sucked. It was a lot more uphill than I was expecting. I was pooped by the time I arrived at my car. An over 14 miles and 9 hour adventure. I wasn’t too impressed by the middle fork trail honestly. You’re not by the river for very long and not much to see besides through-the-trees views of Garfield Mt. Only one decent stream crossing before Cripple Creek. Not a hike I would do solely for that trail. It’s more of a connector trail to farther away destinations. It was a long, fun and tiring day.

We hiked to the small loop that runs down to the river, just about 3.5m in. This is a good spot to stop for lunch if your aim is a less intense day. 

Trail is in great form, just a few muddy spots but otherwise a wonderful mossy walk. Noticed a lot of Trillium and Western Lily of the Valley. The Middlefork is a classic hike and super accommodating, just decide how far you want to go.

We hiked 4 miles out and back with our small dog. Like the other reviewer said, so many Pacific Trillium and Lily of the Valley, as well as the teeny stream (or redwood?) violet! Great trail for most, including dogs.

I attempted a longish "figure 8" hike of both the Middle Fork Snoqualmie River Trail and Dutch Miller Gap Trail between the Dingford Creek/Dutch Miller Gap parking area to Hardscrabble Horse Camp.  My "figure 8" route started on Dutch Miller Gap trail, cut over to Middle Fork trail at the Goldmyer bridge, returned on Dutch Miller Gap Trail, and then I started the last leg:  the Middle Fork Trail from Goldmyer back to the parking lot.

I was foiled by Burnboot Creek, which was running strong.  This creekbed is probably an easy hop in August but I wasn't prepared for a serious river crossing today...so I returned via Dutch Miller Gap Trail.

The Dutch Miller Gap Trail, being an old road bed, is rather boring.  The only highlight is Dingford Creek Falls, which really was breathtaking today.

The Middle Fork Trail b/w Goldmyer and Hardscrabble Horse Camp is a pleasant forest walk.  Moderately hilly and somewhat distant from the river.  I prefer the lower section (hiked in January) b/w the Middle Fork Trailhead and Dingford Creek - more hilly, more scenic, IMO.

Caution:

- The Middle Fork/Goldmyer Road is, indeed, a heavily potholed and rocky hell.

- One major blowdown across the Middle Fork Trail just northeast of the Goldmyer bridge, which required some scrambling to climb over.
