At this time of year there isn't many places in south east Queensland comparable to Girraween. Cool nights and not-too-warm days with the kind of stunning, impossibly clear bluebird days we've been having are typical.
Girraween isn't a big park so any dome you fancy spending the night on is within the scope of a weekend walk. This weekend we chose Twin Peaks, which we hiked to via Mt Norman and returned via the Aztec Temple and Underground Creek. There is a great leaf covered dirt campsite on the eastern peak that is just big enough for a two person tarp.
