Haddon Corner

we were out there about 3 weeks ago, left Birdsville headed for Windorah and turned off the developmental rd onto Cordillo Downs Rd. followed that past the ruins and shearing shed and if you stay on that road you'll end up at Innamincka. we didn't go to Innamincka though, we turned off that road though about 36 klms past the shearing shed and then hooked up with the track that runs back North to Haddon Corner. if you don't turn off to Haddon Corner, that road runs back up to the Birdsville Developmental Road. it sounds like you want to visit Haddon Corner on the way to Birdsville, so you'd be possibly doing that drive in reverse to what we did depending on where you intend coming from.
for a better detail of what's out there, check out this trip report i've just about completed on another forum, you'll have to join up to view it though. the particular drive i'm talking of is on day 8 of this thread http://www.myswag.org/index.php?topic=30925.0 , though you may be interested in reading the other days to see what we visited around the Birdsville area also.
cheers

Short answer yes you can you do not need to retrace you're steps

G'day Tony,

to see Haddons Corner and Cordillo Downs from Birdsville, you will have to retrace your steps at some stage.

The track into Haddons Corner stops there and doesn't continue through to the Cordillo Downs Rd.

If you drive directly to Haddons Corner, then down to Cordillo Downs you only have to back track form the turn off to the station. That way you do miss the Waterhole near Caldelga HS ruins but it's the easiest way to se both Cordillo HS and Haddons Corner.
