A challenging hike down to the Hilina Slump.









FATMAP difficulty grade



For a more serious hike in Hawaii Volcanos National Park with stunning ocean views, try on the Hilina Pali Overlook loop for size. A big part of what makes this hike challenging is that it begins by descending a steep 2,000 vertical feet from the overlook to reach the loop.


If you're uncertain that you can finish this quest, don't even begin! The loop portion of the hike is located on the Hilina Slump: "a semidetached landmass sinking 4in each year, and which may be primed for cataclysmic collapse," according to [LonelyPlanet.com](https://www.lonelyplanet.com/usa/hawaii/hawai-i-volcanoes-national-park/attractions/hilina-pali-overlook/a/poi-sig/1301723/1333405).


If the whole thing were to break free, it could trigger 1000ft waves that would annihilate Pacific civilization; though some scientists believe debris piles from previous slumps may hold Hilina in place." Be sure to check out The Slump before all nearby civilization gets annihilated--go do this hike now!
