Roundtrip, the Pipiwai Trail is about four miles and I THINK it took us around two hours each way with stopping and a little exploring, although maybe it was more than four hours because we spent some time at the Infinity Pool and at the falls at the end. Anyway, it's not a difficult hike at all and it will take a solid four hours, so yes, it's a big chunk of time. And it's allll the way at past Hana too although it is right across the street from the Seven Deadly Pools.

We really liked the Four Falls of Na'ili'ili-haele (from Maui Revealed), which is right near the beginning of the good stuff on the Hana Hwy...a little muddy/difficult in places, but lots of bamboo groves and rocky streams and those wonderful four falls--similar to Pipiwai but without the huge falls at the end.

Also, you'll love the Surfside! Make sure you get out there and grill something in front of the sunset!
