Pinnacles is one of the smaller national parks and is off the beaten path, but it is definitely worth a visit if you like day hikes. The Condor Gulch-High Peaks-Bear Gulch Cave loop is one of my all time favorite day hikes. The park might be disappointing if you intend to stay in your car. The park is not highly developed and most of the development is on the east side. (There is no road connecting the east and west side of the park.) The visitor center is pretty small and there is only a small store at the campground. However, there is a lot to see if you are willing to hike a little ways; condors, caves, rocky peaks, nice views, and even a small lake. Parking at the trailheads can be a challenge during busy weekends, but fortunately there is a shuttle that runs from the campground and overflow parking lot to the trailheads during busy periods. It gets very hot during the late spring, summer, and early fall, so hike early in the day and carry lots of water if you are there during that time of year. The best time to visit is during the early spring or late fall.
