Traveling

Well im going to take a year out before i go to uni and im planning on going traveling.
Are there any places you suggest going, i want to do alot of volunteer work so i make the most out of my time, meeting and helping other people and animals.
If you have any advice, tips, links to volunteer work or anything else it would be much appreciated, i will be going in January and going for 7-8months

There a site called gap year.uk im not sure where your based but it might give you some good ideas!
