Superb views
For one, there has been a lot of issues about trash in the city but considering that the Castle was relatively clean. All public bathrooms in Italy are more than likely less than favorable and tip number 1 is to bring toilet paper with you wherever you go. Most of the castle is closed off and still being used and not available to the public. However, it offers some impressive views from the top of the castle. Across the water on a beautiful day, you can see Mt. Vesuvius. It is right in the middle of Naples so you have panoramic views of downtown Naples as well. Don't forget that the castle sits right on the water. The Italians often use this area for swimming and boating. It is not uncommon to see them jump off of the bridge into the nearby water. There are many street vendors and the area is close to some nice shopping. We went during the day but I would imagine that the place lights up nicely for a romantic walk along the boardwalk at night. The local restaurants open up for lunch and offer a delightful cuisine to choose from. We drove and was able to find parking a short distance away and our car was not tampered with. Although, tip #2 would be not to keep personal or expensive items locked in car. Always keep them on persons. Parking is relatively difficult though especially in the months of July and August. Traffic is not for the faint of heart either so public transportation should be considered and planned thoroughly. This is not a guided castle so do not expect someone to explain anything about the castle unless you go with an outside tour. However, there are a few spots were the castle is explained partially but most of it is written in Italian so do your research beforehand. It shouldn't take you too long to visit so you can easily do it in a few hours and grab some lunch before seeing some other sites or doing some shopping.
