Be mindful of the weather! If it is too hot you may not enjoy yourself. Also storms are very common here. There are water fountains and soda shops in the park though. You will have places to refill your water bottle and grab lunch.
You will also want to leave time to explore the town at the base of the mountain- regional food and fun little shops are abundant in Chimney Rock Village.
If you are not up for a hike, you may enjoy Chimney Rock Riverside Park, located at the base of the mountain. It is FREE. Very scenic without the hike.
