Love Himalayas, We did the trail up to the Mirror lake a week ago just to get a feel of it and to train before the real climb. We returned to the parking lot in the dark. The trail to the Mirror lake is quite easy and is completely passable with a headlight only. We even had no problem to cross in the dark that roaring waterfall which is approximately one mile away from the portal. No worries about the lower trail at all.
Chad, thank you for your wishes for our tomorrow's climb!
