DirectionsIf you're staying in Waikiki, the easiest way to get to 2010 foot Mt Tantalus is to take Ala Wai Boulevard, which borders the canal, until you get to McCully Street. Make a right on McCully until you reach Beretania Street where you will make a left.
In a few blocks you'll come to Punahou Street where you will make a right. After .3 mile there is a traffic light at Nehoa Street. Make a left and go three blocks to Makiki Heights. Make a right. One block later you'll come to a small park where the road forks.
Take the right fork and you've begun your journey on Round Top Drive. The road is a long nine mile loop, so you can also take the left fork and return to the same spot.
