It's a 4.5 really because a lot of people (almost too many) are at this location by sunrise. There are a few parts where you'd have to wait for people to pass because it's so narrow. I parked and started my hike before the break of dawn. Brought my dog. She's great at hiking/climbing but there were parts (last 1/4 mile to summit) where it got w little dicey and I had to haul her up. If you have a larger dog (50 lbs.+), bring a harness that you can use to carry your dog a bit.
