I'm also a GoPro user and I find it really awesome for travel as a backup/for fun camera. I wouldn't use it for a main camera for travelling though, I have it cause I'm using it for my studies, and occasionally use it for other purposes.
I travelled in Paris, London, Portugal & Spain with my Canon 60D + some lenses and frankly I find it really troublesome when it comes to carrying it around. I ended up not really enjoying my trips as the weight of my bag really kills me at the end of the day.
Recently I sold all my gear and got myself a Fuji X camera, which I brought with me to Seoul and I really love it. It never goes into my bag and it's so light I don't even feel it there

.
What I would recommend for a backpacker is the X-M1 kit. It comes with the 16-50mm and some sellers still have the promotional set that comes with a free 18mm lens. the X-M1 + 18mm is a really really compact and powerful combo, awesome performance in low light. Can get it for about RM2.5k or so, recommend you Mr.Oss from Garage Sales.
If you have the budget, go for the GoPro as well, I don't think you'll regret it if you go to places where you're gonna be going to the beach and doing stuff like parasailing/extreme sports. You'll definitely love the camera.
But as LordEnigma mentioned, GoPro videos straight out of the camera are just so-so. You have to do some touchup with exposure/contrast/temperature with the free GoPro software, but I don't regret getting my GoPro one bit. It's definitely more flexible to use than normal cameras (of coz, you have to spend a bit more to get accessories like the flex clamp/extra batteries/LCD backpack)..
Also, enjoy your trip! Would love to take a long trip away right now :/
