Isaac Hale Park Spring
Isaac Hale Park Spring delivers 97°F water—genuinely hot—on the Big Island's lower East Rift Zone, creating one of Hawaii's most thermally impressive accessible springs.
The spring emerges just 55 feet above sea level where volcanic slopes meet the Pacific Ocean in a landscape repeatedly reshaped by lava flows from Kilauea. Water pools in small basins surrounded by dark lava rock and pioneering vegetation, creating a dramatic geothermal feature where tropical conditions meet volcanic heat.
Formation occurs where groundwater circulates through recently active volcanic terrain near Kilauea's lower East Rift Zone. The 97°F temperature reflects proximity to shallow magma chambers and active hydrothermal systems common to this geologically young landscape shaped by repeated eruptions over millennia.
From Pohoiki Road, walk 780 feet (238 meters) across lava terrain to reach the spring pool. Water stays intensely warm at 97°F year-round—check current conditions before visiting. The 2018 volcanic activity modified access routes; confirm current trail status. Bring sturdy shoes and plenty of water. No facilities.
