Hana Highway Maui
Near the 21 mile marker on the Hana Highway you'll cross over Wailuaiki Stream Bridge. If you can find a place to park (usually just beyond the bridge), pull over and take a look at the 50ft waterfall cascading just under the bridge. This stream and waterfall can dry up if it hasn't rained lately, as the East Maui Irrigation (EMI) company diverts a lot of the water upstream. Speaking of upstream, a hunters road/trail starts mauka just up the road from the bridge, and it goes to a variety of other waterfalls upstream that are almost always flowing, but this trail is on EMI land.
