These natural pools along Wainaku Avenue near Hilo are where the Big Island shows off its volcanic personality. Water churns through underground lava tubes between the pools, creating that mesmerizing 'boiling' effect that gives this spot its name. The series of pools cascade down to Pe'epe'e Falls, an 80-foot waterfall that thunders into a deep swimming hole below.
This is raw Hawaii - no railings, no crowds, just you and the power of volcanic geology. The lush rainforest setting makes it feel like you've stumbled onto something ancient and untouched, which honestly, you have.
💡 Insider Tip
The rocks around the pools are slippery when wet (which is always), so wear shoes with good grip. Park at the small pullout and follow the short trail - it's unmarked but well-worn.
