My Son and I hiked down to the panel and back up in about 85-90* temps. Coming back up was a little bit hard on my old bad out of (never was in) shape self, but not really all that tough. We had people sitting waiting for us back at the trail head so pushed it a little bit and did the whole thing round trip, including all the picture takeing in under 3 hours.
It was dry when we went and I think I could have driven a Lincoln Town Car to the trail head without much issue - seriously.
