Heylo all

A mate and I are keen to head out to Echo Valley sometime.
Now the problem is this...we know ROUGHLY where it is (up from Boyes Drive)... But we don't know where exactly to park or how long the walk-in is. We both work close there so were wondering if a 4:30 PM arrival time at parking lot was enough to get up and then boulder a little and maybe walk down in the dusk/dark (bergies...?).
Anyway any info you all could provide would be awesome.
I'd check Cutloos's site for the topo/etc, but it is still giving that "permissions" problem.
Anyone have a/the topo in PDF?
Cheers,
Cuan
