Getting There: At Superior, take Diamond Road east past the Town Pump Gas Station for 6 miles; passing the Bark mill and the Magone Ranches to the end of the pavement where the road changes to Trout Creek Road (#250). Continue up Trout Creek Road (~19 miles) until you top out on Hoodoo Pass on the Idaho / Montana border.
Continue on Road #250 into Idaho for about 11 miles. About a tenth (0.1) of a mile before crossing the Middle Fork of the Clearwater River, road #250 crosses Long Creek and stays left of the Clearwater River. If you cross the river and get to the Cedars Campground, you have gone too far. Stay on road #250 for another half (.5) mile then stay left on road #295 up Lake Creek for about 4.5 miles. There will be a picnic area / trailhead with a vault toilet at the intersection.
The left fork (road #5450) goes for a mile to a gate and the trailhead to Goose Lake and Steep Lakes; the right fork continues up Lake Creek for 1.5 miles to the trailhead for Fish Lake. Road #295 becomes trail #419 at that point; okay it is a road that any 4-wheel drive can make to the boardwalk about 1/2 mile from the lake; however, I believe the road has a 50-inch width limit. I had previously written that trail/road #419 was closed due to a lawsuit pertaining to the forest violating their travel / elk habitat rules.
Apparently, the forest is in the process of amending their rules in 2024 so they can reopen the trail/road to motorized use. But according to what I have read, the closure is still in place as the amendment has not been officially signed and implemented. Of course, that didn't stop the SxS-4x4 crowd from tearing down the signs and removing barriers so they could drive into the lake in 2024; I hiked into Fish Lake in 2024. My guess is that the road will be officially re-opened in 2025. Stay on this well-defined route for 6 miles to Fish Lake, the largest lake in the Great Burn area.
Trail #419 moderately climbs up the valley crossing two creeks (Siam & Japanese) and several other small creeks with just the middle couple miles a bit steeper, so it is easy to make good time. Once you cross the 350+ foot boardwalk you are about 1/2 mile from the lake.
Getting There: Take the Fish Creek Exit on I-90 and proceed up Fish Creek Road #343, then the right fork on road #7750 (Iowa State Research Center) that ends at the Clearwater Crossing in 6.75 miles. The clearwater crossing has a small campground (3 sites), 2 vault toilets and a Forest Service Guard Station. 
Cross the West Fork of Fish Creek on the stock bridge to pick up trail #101. Follow trail #101 for 9.25 miles to Foley Basin where trail #114 to the Lower Siamese intersects.
Along the way you cross the West Fork at mile 3 where you intersect trail #110 coming out of Cedar Log Creek and a camp site and swimming hole is just 100 yards from the crossing. The bridge is old, it has been there in excess of 50 years as I remember it back then; nowadays a single hiker can make the bridge flex by just walking across so it might be gone in a few years. At five miles the trail (#121) out of Indian Creek crosses the West Fork and connects with trail #101. At Foley Basin the left fork (#101) climbs up to the state line and Fish Lake in a little more than a mile. Continue down the hill for another 1/3 of a mile to the lake, a grand total of 11 miles.
At the Lake: Fish Lake is the largest of the lakes included in these descriptions; a float plane could probably land and take off. There are multiple campsites (10+) around the north shoreline and the east end of the lake and three outhouses, with multiple improvements like stairs to the lake and boardwalks to cross sensitive areas due to the motorized traffic allowed into the lake prior to 2023. Prior to 2024, I never camped or fished (cutthroats) at the lake, just passed by on the way to or from the Siamese Lakes and I previously (pre-2024) never taken any pictures at the lake even though I have walked right by it several times. 
Over Memorial Day weekend in 1986 I dragged my Mountain Bike and skis over the old swinging bridge at the Clearwater Crossing for the end goal of making it to the state line and possibly Fish Lake by going up the West Fork of Fish Creek, trail #101. 
I was able to ride my bike with a full pack and skis to the swimming hole just past the 3-mile bridge. I had enough of the bike at that point. I then hiked until I was almost into snow and camped for the night at a camp a couple miles past Indian Creek. The next day I skied up to the state line overlooking Fish Lake, it was a tough go. In the end, I was able to make it to the state line that day; skied back to camp and hiked / biked back to the Clearwater Crossing.
A couple years later Larry Bauer and I tried the same trip over Christmas. We camped the first night at Indian Creek and it must have snowed 2 feet that night and was still snowing in the morning. Trying to break trail in all the snow with full packs was not working so we bagged it not to long into day two. I think we had planned for a 3 or 4-day trip.
When the dude ranches were in full swing, the road into the Hole-in-the-Wall ranch (now Iowa State Research) was plowed during the winter. There was a year-round caretaker at the ranch and there are also some private residences. I don’t know if the road is still plowed but it is worth checking into. I would guess that the Nine Mile Ranger District may know that information. Both the West and North Fork trails are good cross-country ski trails. The North Fork trail is good all the way to the Greenwood Cabins with no real creek crossings until then. The West Fork trail doesn’t have a creek crossing until the creek that comes out of the Siamese Lakes and at Foley Basin, as long as the bridge at 3-mile is still there. Between those 2 creeks there are some steep & open slopes so avalanches could be a concern if making it that far on skis.
