This is a very large park with many different kinds of hiking trails and viewing areas. Some of the "trails" can even been done in your car. There's so much to see that it's impossible in only a day or 2. I went in July and really enjoyed the intense heat, but that's just me. Go in the fall or spring if your not into the heat and bring lots of water. Try to plan out the spots you wish to see so your not driving hours in the park between locations.
