Make reservations online and come very early. I'd also advice to take the stairs as the queue is smaller. The place is safe, protected by barriers and security, as well as sometimes military officers. The view is a staple of the discovery of Paris. However, Pompidou center's view might be better and sometimes less crowded. Plus, the 7th floor of Galeries Lafayette has a great sight too.
