If you're looking for something to do that's a little bit active and romantic or even something to tire out the kids I would definitely recommend hitting up the Riverwalk from under the Storey Bridge over to New Farm. If you've got the kids I would recommend parking along bowen Terrace Fortitude valley and walking down under the bridge and along the floating walkway until you get to New Farm park. If you're looking for a little more romance try starting at new farm and walk up to Bowen Terrace right on sunset. It's a great place to take a picnic and take in the beauty of Brisbane.
