Woman painter with canvas in Perouse Bay. Maui. Hawaii. Haleakala's last display can be seen on Mau'i's southeast shore at La Perouse Bay. Scientists estimate that in 1790 Haleakala erupted to form the jagged lava rock coastline. Now there is a monument and ruins of Hawaiian natives who made their home on the sharp a'a lava rock. La Perouse is the end of the road, literally, in south Mau'i. It is located at mile marker 7 at the very end of Makena Alanui Road. From Kihei take Piilani Hwy south to Wailea. Turn right on Wailea Iki road and bear left on to Wailea Alanui Road which turns into Makena Alanui. Look carefully around you as you drive between mile markers 5.5 and 7. On either side you should see fields of a'a littering the landscape. Just past mile marker 6.5 look mauka (mountain side) and you can see where the lava spewed forth from Kalua o Lapa cinder cone. Once you reach La Perouse Bay you may have to park on the road. Make sure not to park on any lava rock as it can ruin your day with a flat tire. (Trust us we know.) You can walk through the lava and explore the sea estuaries. This is a favorite place for dolphins and local fishermen. Make sure to wear sunscreen and be prepared for a lot of wind. In ancient times the area was known as a site where Huaka'i po, "Night Marchers," roamed. These are restless spirits who are trapped on earth causing mischief at night. Every island has its tales about sightings of Night Marchers, but especially the Big Island.
