Suggestions for a post-graduation trip?

<p>My roommates and I are looking at taking a trip together somewhere after graduation in early May. I currently have my vote in for Iceland. I'm not sure how all of my roommates would like the amount of nature exploration I would like to put into such a trip, but the flights are relatively cheap!</p>

<p>Any other suggestions on where might be good to go or what would make a good trip?</p>
