From LAHAINA - Drive Southbound on Hwy 30 (Honoapi'ilani Hwy), as the road opens up after the tunnel, you will see a sign for Maalaea Harbor, and you will see Buzz's Wharf. Turn right at the Maalaea Harbor Sign. If you pass the Maui Ocean Center on your right - then you've gone TOO FAR!
From KIHEI / WAILEA - Drive Northbound on the Pi'ilani Hwy (Hwy 31), or S. Kihei Rd and follow the signs that take you to Hwy 31. Eventually, that road will end in a T-intersection. Get in the left turn lane to follow the signs pointing to Lahaina. Turn left and get onto Hwy 30 (Honoapi'ilani Hwy). After a few minutes you will see the main intersection for the Maui Ocean Center on your left. Turn left at the lights and drive into the harbor.
