We just visited there a couple weeks ago, and the answer is, "it depends" on what you choose to do between those two attractions. First, the USS CONSTITUTION is there, but not yet open (as of our visit on Friday, July 28). It had just returned from the shipyards, and the ship was still closed. It may have re-opened since then. If it is closed, you will only be able to do a "walk-by" which will only take you a few minutes. The museum nearby is good for a 30-40 minute visit as well, with lots of interesting stuff inside. From the USS CONSTITUTION up to the Bunker Hill site & monument will take you a good ten minute walk, all uphill, so leave a little time for that in your equation. Then, once you get up the hill, it all depends on what you want to do. There is a great re-enactment speaker dressed in period clothes, who will speak for about 15-20 minutes. There follows an exhibition on firing the muskets of the day which is another 5-10 minutes. If you care to walk up the almost-300 steps of the monument itself for the view, add another 15 minutes (assuming that you are in shape). So in summary, two hours much be a bit rushed, but it could be done if you didn't stop too long at any one attraction. BTW, if the CONSTITUTION is still closed, there is a destroyer at the pier, the USS CASSIN YOUNG (spelling?) that you can board and tour, so that may be on interest as well. (Then again, I am a retired Navy Captain, so these things interest me perhaps more than most.) I hope you enjoy your day there! Larry

There is usually enough parking in garages but try street parking first. Meters ARE in effect everyday EXCEPT Sunday's and holidays. Max parking at meters ... 2 hours. There are some free, no meter spaces but READ THE SIGNS...if the space is assigned to a condo building you will be towed.
