It doesn't take much of convince someone why Versailles is a must see. Originally built by Louis XIV in the 17th century, it was the royal seat of the Bourbon dynasty until the French Revolution overthrew the monarchy nearly a century later. A testament to absolutism and extravagance, Versailles epitomized the Sun King's reign and transpired into every other European monarch emulating his feat with a palace of their own.
Just 12 miles southwest of Paris, Versailles can easily be visited by Metro as parking can quickly fill up before 9:00 a.m. in the summer time. A general adult admission is little more than 15 Euros, with guided tours, audios, and additional buildings on the grounds available for additional fees. Much of the palace of wheel chair accessible, the vast gardens are open for walking, and restaurants and a cafeteria are located within the palace.
Anticipate long lines at the entrance, then spend a minimum 2-3 hours touring this World Heritage Site.
