Visit to the basilica Sacre Coeur is free, but if you want to get a view from the top, you need to pay for it. View from the dome cost 6 euro person, not included into the Paris pass. You have to take 300 steps; the way to the top is narrow and winding- if you have any physical impairments you need to think about going to the top. The view from the dome is spectacular especially on a clear day. At the distance you can see an Eiffel Tower which looks to be about 5 inches tall. I recommend doing it especially if you like photography.
