Did this hike 2nd week in October. Some snow on the ground once you reach Summit Lake. Took a wrong turn at the junction past Summit Lake and accidentally added about a mile before consulting map and realizing mistake. Didn’t make it to Maggie in time so ended up camping 1st night at Twin Lakes where we saw 2 structured fire pits. Trail from Twin Lakes to Maggie can be difficult to spot at time so we consulted the map quite often. There’s about 10+ camping sites at lower Maggie. Recommend downloading the AllTrails map if taking this route as opposed to the easier to follow Summit Trail. Great views, worth the trek!!!!
