I went on a weekday and only saw max 10 other people. I did the ridge walk right to the summit and had it all to myself. Most people didn't attempt the summit. It definitely increased my heart rate at the last little stretch right before the summit because there aren't many footholds. But the summit is so close you just have to do it! If you go slowly and carefully you should be fine but if you have a fear of heights, it might not be the greatest. Worth it though! Steep ascent the whole way from the bottom but I'd recommend it for a clear day.
