Re: biking on Maui. There are two great coastal roads on Maui for biking. Hana Highway from near OGG airport to beyond Paia has wide shoulders (about 7 miles from near the airport until a major gulch). Gulches are the problem with many coastal roads in Hawaii, such as Hana Hwy on Maui and Belt Rd. on BI .... the gulch hairpins are often wet, have red mud and fallen boulders on the shoulders, have steep approaches, and impatient drivers. The second pick for "safer" biking on Maui is Lower Honoapiilani Rd. on the Lahaina side ... about 5 miles, dry, sunny, residential and beach traffic. If you like hills, gulches, and lots of them, along with lolo drivers, try the remainder of Hana Hwy, or the windward side of West Maui.
