For everyone looking at Stephen Fisher's review, He did not actually do the Palmer Loop. He got lost and went up High Drive, which is a dirt road. If he had paid attention to the signs, maybe done a little research he would have enjoyed his experience and actually hiked the Palmer Loop. Its unfortunate when people get lost and can't write a proper review, but look at all the others under his and you'll see that is a great 5+ mile hike/walk. Great scenery throughout the ascent and at the top.
