The trip to the Waihe'e Valley from West Maui takes you south from Lahaina around the southern tip of West Maui where you head north again towards Ma'alaea Harbor. After you pass Ma'alaea stay straight on Highway 30. (Don't bear to the right as if you were going to the airport.)
If you're coming from the Kihei and Wailea area, take Highway 31 until it ends at Highway 30 just north of Ma'alaea Harbor.
Highway 30 takes you into the small town of Wailuku, the seat of government for Maui County. In Wailuku you'll take a right on Main Street (Highway 32) and in two blocks a left onto Market Street, which will become Highway 330.
You'll soon come to a Y intersection with Highway 340 where you will want to bear left through Waihe'e Town. Look for the school on your left and then keep your eye out for Waihe'e Valley Road. Turn left and continue on until you see mile marker 5. You'll see a grass turnout where you can park just past the taro patch on your right.
Of course, if you travel with Maui Eco-Adventures, you won't have to worry about any of these directions! All you will need to do is enjoy the ride and look at the beautiful scenery. From the Ka'anapali Resort area the trip will take about an hour. From the Kihei and Wailea area, the trip will be somewhat shorter.
