A walk very similar to the one Richard took is described in Rick Steves'
Paris guide. But I want to add that Montmartre has much lovelier streets
sights. From the Place du Tetre, follow the steps down to the Dali museum,
and then turn right. This leads to a beautiful residential area, traversed
in part by that goofy-looking Montmartre tram.
Wander around a bit before heading for the downhill walk to rue Lepic.
You will see one of Paris's loveliest residential neighborhoods. And if
can, avoid Pigalle. Leaves one feeling a little slimy, even after just
walking down the street.
On the way up to Sacre Couer, stop at the relegious shops leading to the
cog-incline if you like relegious souveniers. These are great and have
prices. I bought the best Jeanne D'Arc (I think the only one in Paris!)
there, but gave it as a gift to a sick friend. Wish I had another one.
