For years I have used a Panasonic TS2. Their TS series is awesome, great photos and video, easy to use and bomber. Mine is getting pretty old now and I sometimes let my 4 year old wander around and take pics with it, as long as it's attached to his arm he can't hurt it at all. Get some funny pics that way too!
They are a lot like the Olympus option that was mentioned.
They either have just released or are planning on releasing the newest model, TS7. It looks pretty rad, there is a review posted
here.
I have a gopro as well (a gopro 1 maybe, the thing is ancient), and its great for video, but I prefer the camera for pictures, you just have a bit more control over what you are getting in terms of pics.
