Im looking to travel to South america next year, anyone know of some good websites,companys to look at?

* my blog is candkperu09.blogspot.com I have information about my trip on there already and im leaving in 10 days and hopefully will have an updated post every day that i can. hi mark..i am traveling to peru in may for a month. im doing half with a volunteer agency at an orphanage (they have many options ) called rustic-volunteer-travel...they have many different places and choices (dont have to volunteer)...but i am doing the other half of the month with a group bestperutours.com..they are amazing. you can completely customize your trip based on what you want to see and your budget. i chose to create my own student adventure 11-day tour. im hiking the inca trail to machu picchu, white water rafting for 2 days, then trekking in the amazon complete with zip-lining, etc...you can do some crazy things like sand-boarding in the desert, etc..its all your choice..and i think they include some of the neighboring countries as well, especially in the amazon tours. i have a blog about my trip that i will be updating as soon as i leave, so let me know if you have any questions or want to see my pictures!
