Perhaps the most intriguing part of the journey is the hike through dense jungle to reach the hidden entrance of Vaiula Cave Pool. This isn’t your typical tourist stop—getting there involves walking along a 150-meter lava tube, which makes for an engaging adventure.
Travelers who’ve done it mention the fascinating underground passage, with horizontal sections and a small talus slope that sometimes requires bending down to avoid scraping your head.
