The Ravenclaw dorms and common room are in Ravenclaw Tower (a
counterpart to Gryffindor, which also occupies a tower). Ravenclaw
Tower is on the west side of the Hogwarts castle. This actually
appears in (the 5th book, chapter 10), according to the HP-Lexicon:
http://www.hp-lexicon.org/hogwarts/castle/hogwarts_inside.html

When Fred and George give the Marauder's Map to Harry, it is described
as showing "a set of passages he had never encountered," some of them
leading into Hogsmeade. Fred says "There are seven in all," apparently
meaning "seven passages that lead to Hogsmeade": 

* four known to Filch 
* one opening behind a mirror on the 4th floor of Hogwarts, which is
now caved in
* one with the entrance beneath the Whomping Willow, which leads to
the Shrieking Shack (ch. 17)
* one from the 3rd floor of Hogwarts to the cellar of Honeydukes sweet
shop in Hogsmeade.

These are "many" of the passages on the map, so there are apparently
other secret passages within the school. (ch. 10)

The HP Lexicon describes the map at
http://www.hp-lexicon.org/atlas/hogwarts/atlas-h-m-map2.html
Some of the information about the map here is different from what I
found in my quick reference to PoA, so it probably includes additional
secrets that Harry learned later on.

At this point, some aspects of the map are still left open, to be
disclosed (or speculated about) later.
