Mananole Falls (or Mana-nole Falls) is a light-flowing tall waterfall (supposedly 1000ft tall) deep in the Waihe'e Valley of West Maui.
I don't think you can get close to the waterfall, but you can see it from above along the Waihe'e Ridge Trail and from below along the Waihe'e Valley Trail (as you can see from the photos on this page).
Both times I have noticed this waterfall from terra firma were on our visit to Maui in September 2003. The first one was from the Waihe'e Ridge Trail near the Waihe'e Valley Overlook. The second one was along the Waihe'e Valley Trail quite far into the hike before the Ali'ele Falls.
More recently in 2007, we did a chopper tour of West Maui and Molokai, and in that particular trip, we flew into Waihe'e Valley where we got to see this waterfall from closer up.
To provide you with a little context, we generally stay in West Maui in either Lahaina or Ka'anapali. The most straightforward drive from say Lahaina to Wailuku would be to drive south on Hwy 30 and wrap all the way around the south end of West Maui taking a little over a half-hour to go 22.5 miles. Both Waihe'e Ridge and Waihe'e Valley Trails are accessed north of Wailuku.
You can use the form below, but if you find our host's interface too troublesome to use (especially if you're trying to upload photos), then just send a text submission anyways using the form, but also let us know that you'd like to attach photos. If you've provided an email address via the form, then we can reply back acknowledging your request, and you can then reply to that email with your photo attachments. We're very sorry about this, but there's not much we can do about SBI's terrible interface.
