In reply to peebles boy:
If I were going to own one camera, it would be a compact, not a larger camera.
For climbing in particular, a large camera can be a pain to carry where it is easily accessible.
I have a lot of cameras. The ones that get used the most are my compacts.
Given your budget, this is the camera I would buy: Sony RX100 ii You can pick them up on ebay for a little over 300
