Earlier, Tony, Sid and Malcolm hiked from Puu Konahuanui to Makapuu in 2 days, 1 night (spent above Waimanalo, on a very rainy, stormy night). We left the road (Tantalus Drive) at about 8 am and walked out at about 4 pm the next day.
Water can be a problem for some. Aside from Lulumahu valley at the start, there is no reliable source.
Knut Peacock, Jim Fleming and Malcolm attempted a more leisurely pace--two nights, the first at Puu Konahuanui--and spent 40 hours in clouds and rain. We walked out at Niu Valley, dry, in the early afternoon and spent $5.00 for a case of Primo. It vwas gone by the time Fleming's mom picked us up 45 min later.
If you trim the trails, please don't leave diagonal-cut stems in the path. I have a scar from a punji stick on the Puu Konakuanui-Olympus trail. A'a I can handle, if I know to pick my footing, Thanks
