I got this from DCL website
On this tour you will:
Take an approximate 45-minute drive along the Lower Corniche to Monaco.
Ride an escalator and elevator up the cliff and enjoy a 45-minute guided walking tour (wear comfortable walking shoes) passing by the Oceanographic Museum & Prince's Palace and an inside visit of the Monaco Cathedral. Note: This tour includes approximately 0.5 miles of walking at a steady pace, part of which will be on cobblestones and uphill.
Does anyone know what the escalator and elevator is like? I am not that brilliant with height at times.
Does anyone have picture of this
