I was going by the climbing season in Bolivia. June-August is their winter. You could hike in the area year round. Might be harder to climb during some weather. Cheers!
the mountain is also known under the name "Nevado Illusion". This should be mentioned on the main page so that search engines can find the page. I've alse read about a height of 5370m
Thanks, I've added the name. As I didn't make it to the top I was using the published altitude from Yossi's book. It seems like every mountain in SA is contested to what the 'true' altitude is. Cheers!
