Drove in from Austin on a Thursday, 1st of November and headed up at 10:30. It was low 80s but still warm on the way up and glad to have water and a hat. We are fit and it took about 30 minutes. Wandered around the summit for a while and took our time on the descent. Had lunch under the trees and then took a short trip halfway around the north side. Park started to fill up around noon. We would've liked to spend more time, exploring the Loop Trail and the cave and maybe even camping but that is another trip. Saw Quarry to the west and later, during a tour of the Capitol, found they were the source of the Pink Granite in the Capitol Building.
Spectacular views and a lot of geologic phenomena and nature to see. Drive from Fredericksburg is scenic - only about 15 miles.
The ranger said the Rock is open until 10 pm so you can watch the sunsets from the summit.
I saw a couple of reflectors on the way down but many of them were gone - saw the remnants of glue on the rock surface.
