We went to Waimea Canyon and Kokee State Park in September. The morning ride there was beautiful - lots of great picture taking of the canyon. We intended to hike the Pihea trail to the alakai swamp trail (as described in Kauai Revealed, by Andrew Doughty). We started off around 9:00 am, cool weather, few other people, but did not make it more than 1 mile. This trail is an ankle twister. The day we went was dry so it was hard packed clay-like surface but there is not a flat surface to be found. It was like boulder hopping but on a slick, packed clay. You have to watch your footing all the time, which means you can't enjoy the scenery. I'm in my 50's and hike the Santa Monica Mountains in So Cal without trouble. The Pihea trail I did not enjoy. My teenagers - both fit and adventurous - were the first to suggest we not proceed; they could not envision 4 miles of that only to turn around and rewalk it for a total of 8 miles. We drove back down to the park headquarters, walked through the museum, and enjoyed a picnic by a grassy field. We had enough time to enjoy snorkeling at Poipu Beach. We enjoyed our day, probably more than if we had done the hike, and covered a lot of beautiful Kauai.
