I spent 3 days in the Glacier lake & five lakes basin area, the hike was a bit more difficult than I hade anticipated, the 40 lb pack I was carrying was a bit heavy for the elevation climb & made for a tough go into the glacier lake area, although I took the Glacier trail in, I took the Sand ridge trail back, the trails were easily followed, the trail markings were few & for the most part not well marked, trail signs were knocked down & broken, & left unclear as to which way to go, once on the trail however it was easily distinguished.
The scenery was incredible & really made the trip well worth the effort, the fishing was poor however, & hard to recomend I fished Downey, & Glacier lakes,
If your headed to the five lakes basin for more than a day, I recommend staying at Glacier & day trips to the five lakes basin without packs, the trip down to Five lakes is relatively easy, there are no trails but following the dry creek beds was the way to go, the climb out was also fairly easy, (with no packs)
one quick note, if your packing in, you might want to use the carr lake trail head, the trail head @ grouse lookout is closer, but a very steep climb out ! + there are camp sites along the trail of feely, the island lakes & milk lake to break up the trip & fish.
