What an amazing place to see. We arrived around 7am so there was nobody at the entrance and everybody was just driving thru. We had already purchased our ticket but not big deal as all money going to the preservation of the park. Parking was plenty but was getting full by the time we were leaving. Would definitely recommend going as early as you can in the summer time as it started getting really hot by noon. There is a lot of walking so beware if you're not in great shape specially the way back is all uphill. We saw a lot of wild life including a black bear in the distance. If I could think anything negative is the bathrooms at the entrance were pretty dirty. Specially first thing in the morning as nobody had clean them for a while.
