hello Chloerose and welcome,
if you want to travel the world as a single traveller then this is the place to be. great holidays and such fun to be had along the way, have a look at the tours online or in the brochures and see which one jumps out at you. I have just booked my 10th JY tour for 2014. This is a very safe way to travel, and a vast age range from young to old and all in between,you won't be left on your own unless you want to be and every one gets along very well. I am sure there is a holiday for you, so give it a try and see what you think. If I can help with anything else just ask and I will try to answer.
Cindy
