The top level's upper platform is 276 m (906 ft) above the ground – the highest observation deck accessible to the public in the European Union.

The tower has three levels with observation platforms, at roughly 200, 400, and 900 feet, all connected by elevators and stairs. But there isn't a single elevator straight to the top (le sommet). To get there, you'll first ride an elevator (or climb 775 steps) to the second level.
