I'm looking for fairly easy/scenic hikes to do while we're in the Kokee State Park on Aug. 19. I just read about the 1.8 mile Kawaikoi Stream Trail (rated as easy) but I'm wondering if it would require a 4WD. We'll have about 4 hours to devote to the park/Waimea canyon overlooks before an afternoon snorkel cruise at 2. I was planning to hike about a mile along the Pihea Trail and also do the .3 mile Iliah Nature loop. Will 4 hours be long enough to do all/most of the above? Should we plan on stopping at the overlooks on our way down the canyon in case the Pihea Trail gets fogged in? Any suggestions on making the most of our morning would be appreciated.
