There are numerous steps to get to the top of the cathedral which is not a problem for us since my boyfriend and I love to walk. However, in case you have older people with you who can't climb the stairs, there is a funicular that will take you up to the foot of Sacre-Coeur and you can walk from there. When you do get to the top you will be rewarded with a wonderful panoramic view of Paris for FREE! One true thing about Montmartre that I heard from others is that it's a very touristy place, there's lots of street vendors! While walking up to the cathedral, there were many souvenir sellers interrupting us and trying to sell trinkets and selfie sticks. It doesn't really bother me because I think these people just simply want to earn for a living.
There are many metro stops to Montmartre. The nearest to station to go see the beautiful church is the Anvers (line 2). You can check out this website for other options.
The white marble church is magnificent! The beautiful architecture of the building inside and out is well worth the walk up the hill. They don't allow people to take photos inside but you'll enjoy taking pictures of the view outside the church. This Catholic basilica is located on the highest point of Paris and is surely one of the most beautiful churches I've ever seen.
