What is the best camera/editing software for Youtube roadtrip videos?

[Cat]

I'm trying to find a camera and editing software to take photos/video on a roadtrip I'm doing in a few months. Looking for it to also be relatively easy to post from a PC onto Youtube/social media to let my family see it back home. A lot of interior driving shots but also getting out and exploring areas so something that can tag along with me, possibly go into water (though not exceedingly deep) and have some nice quality to it. Hoping for reasonably affordable as well. Was thinking GoPro Hero3 series but any suggestions welcome as well as if GoPro, which would be best for my needs!
