Yes,
At 16 you can go to Oasis (Zzzzz). There are a lot of people in that zone killing crocs. It can be fairly dull though. You could also go to Unrest. The downside of going to unrest to group at your level is that there aren't any other places to go out that way to find groups.
There is also Upper Guk which often has people in a grouping mood and is much more fun than crocs. I personally spent my teens with one character in Unrest and in Guk with another. Some times you can find groups in High Pass killing Orcs.
