Check with the Park on percentages, but it's often clouded over. The best advice is 1) the earlier in the morning you go, the better chance of a cloud-free view, and 2) display patience. The clouds flow in and out and it is very changeable. Sometimes if you just stand there for a few minutes it will suddenly open up.

Good morning, Just drive up to one of the kiosk and pre pay for the day by CC card. Its easy, and no worries.

no permits required

No don’t go when it is rainy, the visibility for the view points is poor and the trails are wet and slippery, dangerous! Go early in the morning to get the views. The clouds often roll in at noon! Enjoy!

No it is a paved both direction road. Many beautiful turnoff views during the drive. That specific hike is very muddy & a bit strenuous but so worth it! I hope this helps.

Our recommendation is to check with ur hotel if staying at one - there are always folks looking to team up with. Have a wonderful hike... it is awesome

La strada principale ti consente di avere viste meravigliose su tutto il canyon da varie prospettive; se vuoi fare trekking ti posso consigliare il trail che va alle Waipo’o Falls e poi dal Kalalau Lookout l’impervio sentiero che scende fino a portarti all vista di Kalalau Beach
