Did a weekend (9/27-28) backpack at Indian Heaven wilderness in southern WA. The huckleberry leaves are brilliantly red, and grass are yellow, lakes are green, some blue, small and big. We camped at Blue Lake (the bluest of them all) - designated campsites only. However, not much huckleberry along PCT. Actually rather boring along PCT - all woody, shaded, beargrass. I also hiked along Thomas Lake trail for a bit, more meadowy than PCT, but not much berry to speak of. The northeastern part, down to Junction Lake, are full of berries. Lemei trail is a worthwhile side trip: its high point - not much higher, provides views to Adams and Hood. We also scrambled up to Lemei Rock - better view, Rainier and Helen included.
On our way back on Sunday, 2 of us (not me) bushwhacked to South Crater, where they could see the tip of Rainier.
Not a whole lot of distant view on the trail itself. The fall color made up for it. The lakes are pretty, swimmable. A bit cold.
Well, if I go again, I'd camp around those lakes that have huckleberries!
