My girlfriend and I hiked this trail in a two day backpacking trip. We camped out at Shake Camp before leaving for the first day ($15/night, self-pay station) and then left for Maggie Lakes the next day for the trailhead. You follow the trail to Summit Lake for the first part (mostly all uphill) and then go right around the lake once you reach the top (otherwise you have to go all the way around the lake). The pass is absolutely breathtaking. Definitely stop and explore for a little while there if you can. The trail then heads downhill until Maggie. Once you hit Twin Lakes, the trail is difficult to follow and there are a lot of downed trees you have to climb over. Twin Lakes is beautiful and so is Maggie. The trail is basically deserted. Be aware that you need a permit for Golden Trout wilderness (through Sequoia National Forest) and a permit to use a stove. Definitely bring some insect repellent, there are a lot of mosquitoes.
