Short-term volunteering trips for people my age?

I recently got back from a volunteering trip with a group from my college and it was awesome! I’d love to do another one, but the problem is that I’m graduating. Any organizations that provide extremely organized, week-long trips for young adults to go volunteer and help rebuild communities etc? Bonus points if there are other activities involved. I looked at americorps but it looks like they (and many other organizations) require some sort of year long commitment.
