I did Geryon South this past weekend, first ferry to Narcissus Saturday morning, last one out on Sunday.
Saturday was from Narcissus / Pine Valley / Geryon camp site / summit, / back to camp site - about 10 hours at a casual pace.
Sunday a casual walk back to Narcissus.
The pad to Geryon camp site (also known as climbers camp) starts about 15-20 mins. along the Acropolis track from Pine Valley.
Look out after about this time period for a log on the left side of the track which has a notch cut out of it & an arrowed timber sign with 'THE ACROPOLIS' on it.
Step over (left) this log where you will see a small rock cairn & the pad leading up the valley.
It is certainly hard to follow in sections & poorly tagged, but with time & care should only take about 1 hour to camp from the junction.
I found the camp site o.k, warranted we had bluebird conditions & it was pretty dry.
The pad to the south summit leads from the camp site & is marked with red tags, only about 10mins from here to the main access rock scree.
I found the top section ok, the slab was pretty easy, tho care still needs to be taken. The gulley up the final summit block had a little snow on it so was a little dicey in sections, a few climbing moves are needed here & there. I found it technically harder than say Fedders or Hyperion, tho not too bad on the exposure, tho the snow on the bottom of my boot probably increased the 'brown' factor, particularly at one point where looking down the gulley you could see you're fall-line shooting you out & over the edge of the east face

. Certainly harder than the North summit & worth the extra 3 points (yes, it is worth 8, not 5 these days).
A few pics below, terrible weather as you can see
p.m. me if anyone wants more specific directions.
Cheers.
Stuart.
