Rad Reffer Jonathan had these suggestions:
I recommend keeping these sites in mind; others might have more to add:
Sustainable Travel International
Follow the links to "Our Programs" and "Get Involved".
43places.com
A social networking site for travelers.
Frommers
Substantial portions of Frommers travel guides available for free online reading, including recommendations on places to eat, stay, etc.
I would also recommend:
Lonely Planet
Mostly free content. Fairly active forum.
Wikitravel
This site is new and growing but is an excellent source of information. Anyone who's backpacking around the world should consider contributing their knowledge to Wikitravel along the way!
More resources:
dmoz.org has a comprehensive list of web sites related to Backpacking, they also have a section on Budget travel.
And last but not least your local library probably has travel books and resources for you.
