Hi Toni,
I recently walked and can recommend a trip up
Mount Solitary. There are a few different routes you can take depending on how quick you walk, and how much time you have (that particular route could be done in a couple of days if you cut out the loop at the end).
There's also
Bluegum Forest, which is great to get back into overnight walking.
Lower down the mountains, there's
Glenbrook to Springwood, which I did in a day last week (though there are some excellent camping spots along the way).
My next walk will be out to
Splendour Rock next week some time, it looks pretty special.
