the conditions at the moment are excellent. We were there the weekend before last and we climbed 3 different ice pillars. Image from the previous week of that as well here:
The best way is to decent is from the top, over the summit, along the West ridge, scrirt left once you have gone gone up from the little saddle. Then there is a line to the left of waterfall gully that can be used to get underneath the waterfall. Solo Gutter Snipe (to the right ot the waterfall pillars). You would be brave to try and solo the pillars - the lower sections are good, but you top out on rime ice that peels off the slabs. Have fun and stay stafe out there.
