The guide which you can access online or pick up in paper form has a map and very good descriptions of all scenic views, overlooks and hiking trails. There are also many hiking trails ranging from easy to moderate to difficult with a variety of elevation rises and lengths that you can choose from to see petroglyphs, hidden falls, scenic views and nature’s beauty more close up. There is a 13 mile one way scenic loop which you can drive through and see plenty just stopping at the overlooks.
It was just over 60 degrees so plenty comfortable for us northerners and we wore shorts with a long sleeve top, had on sunscreen and carried water on our hikes. The park fee for a vehicle day pass is $15 and well worth the time spent here. Spent half a day in this park in January when we wanted to get out of Vegas and do some hiking and exploring.
