Yes. Celebrían was captured while crossing the Mountains. But that incident was certainly noteworthy, enough so that it got a mention in the books. I have to think that if Arwen had ever been involved in a similar situation, or anything that would qualify as 'adventure', there would likely be a notice of it somewhere.
Instead, we are only told that she spent her time in Rivendell and Lórien, presumably because she had kin on both places.
Contrast that with her brothers, whose trekking about with the Rangers, in addition to going to and from Lórien, was duly noted.
