Hi Leon,
It is a great walk, isn't it.
You were lucky to get the cooling rain. It was 37C today in Sydney, so one can only
imagine how hot it could have got there.
Though it is not as grand as Kings Canyon or the Rock, a night at Rainbow Valley
is recommended.

We spent a tranquil Full Moon there one night a few years back and had the whole
place to ourselves.
