We decided to wander down the track to see where it went. It proved a little muddy in some spots though, so I'd suggest parking at the T-intersection and walking down if it's been raining. The amount of birdlife was amazing.
Cache is a smallish sistema with the usual swaps, log and pencil. Watch out for slithery critters in warmer months.
Please be aware, the wetlands are closed from dusk to dawn
