Managed to snag a parking reservation just a few days before (there was a cancellation), and got there just before noon for the 12:30PM ticket - was let in early (there were plenty of parking spots left). Started around noon for the Hanakāpīai Falls hike, got to Hanakāpī'Ai Beach in about an hour. Not too bad of a hike although there is a lot of downhill, implying lots of uphill on the way back. Got to the Hanakāpī'Ai Falls from the beach in about an hour as well, path wasn't muddy at all, water crossings had big rocks which were convenient, not too difficult, went by some bamboo clusters as well which was cool. Waterfall was very tall, not many people there (a group of 5 and a group of 2, the latter left soon after I was there). Water was refreshing, glad I went. Hike back to the beach was 45 minutes, and then hike back up to the parking lot took about an hour (I was going quite fast though, passed a lot of people). Shaded on and off which helped, bring enough water especially on hot days. The hike between the beach and the waterfall has a lot of coverage, but the hike from the beach to the parking lot not so much. Moving time for parking lot to waterfall and back was about 3 hours 45 minutes, although the person checking tickets said it usually takes 5-6 hours (not sure if he meant including spending time at the beach and waterfall though).
Went snorkeling a bit afterward in Ke'e Beach, water was warm, smooth sand and very few rocks on the ocean floor, saw some fish closer to the rocks on the side. Nice spot, appreciated the showers!
Definitely well worth it, would recommend! Reserve early otherwise you might not get a spot!
