Climbing St. Peter's Dome means either roughly 320 steps if you take the lift partway up, or the full climb of around 551 steps from ground level — either way ending on a narrow walkway with a panoramic view over Rome. It's a separate paid ticket from the Basilica itself, and not recommended for anyone with claustrophobia: the final stretch is a tight, sloped spiral staircase that follows the curve of the dome.

The two ticket options
A lift can take you partway up to the roof terrace, cutting out the first stretch of stairs — but from
there, everyone continues on foot up the same final staircase. Skipping the lift means starting the climb
from ground level instead.
What the climb is actually like
The first part is fairly ordinary stairs. The last stretch narrows considerably and leans inward,
following the dome's curve — tight enough that larger visitors or anyone uneasy in confined spaces should
think carefully before committing.
What you see at the top
A 360-degree view over Vatican City and Rome's rooftops — on a clear day, one of the best views in the
city, and a popular reason to go early before both the heat and the queue for the final staircase build up.
