It's worth spending an entire morning in the park (or an entire day if you want to walk calmly). I went in autumn and it was spectacular, but in summer keep in mind that there are a lot of people and it's very hot besides it's hard to find potable water. There are clean public bathrooms.
The park is beautiful and every space has its magic. A must if you visit the city. If you want to tour the most attractions that the park has you can choose to rent a bicycle or go on your own.
