For short term volunteering, you could do a three week stint (or a couple months, or a year) at a remote community in the Cascades of Washington called Holden Village. Free room and board, various jobs, about 400 people in the summer and less than a hundred in the winter (but always good people), and really, really great hiking. It has a bit of a Lutheran cover, but there are always some non-Christians and, if they are Christian, they're generally the most liberal and accepting kind. posted by Corduroy at 1:23 PM on May 24, 2008
I'll also add that there are many great hikes where you're more likely to see a bear then a person. posted by Corduroy at 1:25 PM on May 24, 2008
This really depends on what you enjoy. I've spent time alone in both London and New York City, and both were great for me because I spent my time in theaters, visiting museums, other historical sites, etc. It can be easier and more fulfilling to do those things alone (if you're into being alone) because you get to see what you want to see, at your pace.
I always fantasize about camping alone (and hiking, and seeing whatever countryside), but when it comes down to it, I think I'd rather have somebody with me at night by the fire. But when surrounded by all the stimulus that one finds in cities, I find being alone super-easy and enjoyable. posted by iguanapolitico at 1:58 PM on May 24, 2008
