Park is right next to the Botanical Garden and the Zoo so definitely take advantage of that and visit if you have the time! You can drive up to each section, hop off, take pictures and hop back on to the next section of the park. We spent about an hour going through all sections and the last section took the most time since you have to hike (easy hike) up to see the hole in the stone phenomena. You'll get some nice pictures on the top!
Make sure you bring water though, you'll need it. You can get through all parts of the park in less than an hour if you really wanted to for those with limited time.
