Ballon Tourist
You need to climb up 30 towers so that means you have to visit fifteen zones (+ then some if there are any bugged towers), so I’d say chances are “not alone”. If you have some high-level people going with you to higher-level zones then I don’t see why not.
If you lucky enough to find another people doing events – yes.
But I think you should be 50-60 lvl.
There are 11 zones that are entirely below level 30. So that’s 22 balloons. The next 10 balloons are in areas that run up to L50. (Yes, that adds up to 32 balloons, since I think everyone runs into at least one bugged balloon in Queensdale.)
However, if you are good at “running” (i.e. avoiding aggro while moving quickly), you can wait for others complete the events to open the gates to the towers. In other words, it’s possible to complete the achievement at your level.
But perhaps not that much fun having to worry about dying that often. Instead, why not enter the Queen’s Pavillion and level your character there? Use experience boosters, food, potions, banners, etc. A couple of hours there and you should be in good shape to handle the balloon events on your own.
