maui underground

the next time you find yourself traveling down the world famous hana highway, consider taking a detour to explore the hidden caves of hana where lava once flowed deep beneath the earth. the ka'eleku cavern, aka the hana lava tube, is estimated to be over 1000 years old and is believed to be the 18th largest lava tube on earth.
if you have ever meandered through the thurston lava tube at volcanoes, the hana tube is a bit longer at two miles and is tall enough to fit a 6 story building. as adventures go, the self guided tour sounds relatively mellow so you don't have to be an experienced spelunker to make the trip underground since pathways have been cleared and guide rails lend a helping hand.
and, for those who prefer to stay up where the sun shines, additional amusement can be had by wandering amongst the red ti leaf plants which form an island style botanical maze on the property.
happy traveling!
