Round the islands interior. do the circuit - a sealed road goes all the way around the island so you can drive, ride or walk around an entire country! a drive takes about 25 minutes non-stop. i guess a pushbike ride would take 2-3 hours and a walk maybe 6 hours. there is lots of nice scenery if not much to do and, going from either hotel, chappelle & partner department store right at the top of the island in ewa district makes for a welcome break at halfway around.
