Kaimu’s black sand beach feels otherworldly – jet-black from recent lava meeting the ocean – and this short hike takes you to a hidden tide pool that looks like a natural aquarium. You’ll walk through jungle trails and boulder fields to reach crystal-clear water teeming with unique snails (opihi), brittle stars, spaghetti worms, pink coralline algae and seaweed clinging to cool rocks. Sea turtles often swim in the distance, adding to the magic. The rocky pool is perfect for a refreshing dip when conditions allow (almost always accessible for submerging), though it’s not for everyone – no ticks or mosquitoes, but the terrain isn’t ideal for disabilities or kids under 5. A peaceful, intimate spot that feels far from the crowds, with that raw Big Island beauty.
The emerald canopy of a coastal jungle and the jagged, vertical cliffs of Makaukiu Point serve as the stage for this 2.5-hour exclusive wilderness expedition.
Operated by Secret Jungle Tide Pool, this journey transitions from a secluded meeting point in Pāhoa to a local secret: a natural infinity pool carved into the lava rock.
You move through a technical landscape of jungle trails and boulder fields, experiencing an environment where crystal-clear waters and a complex ecosystem of opihi, sea cucumbers, and brittle stars flourish.
Because this is a fully private group activity that requires specific environmental conditions, you should secure your Secret Tide Pool hike early to experience this 2026 hidden gem of the Big Island.
Expect a raw, authentic, and physically engaging immersion into Hawaii’s untouched coastline. The transition from the shaded jungle to the sun-exposed lava rocks requires high-quality "reef-safe" sunscreen and sun protection. The environment is one of "secluded wonder," where the silence of the jungle is replaced by the rhythmic sound of the ocean. Note that this tour is not suitable for children under 7 or anyone with mobility impairments, as the terrain is very rocky and requires a steady vertical balance.
Do not rely on flip-flops for the hike or the pool; our agency finds that travelers who bring dedicated water shoes with durable soles enjoy a much more stable vertical experience on the slippery, sharp lava rocks.
Apply your sunscreen before the hike starts; this allows it to fully absorb into your skin, ensuring that your vertical immersion into the tide pool doesn't introduce harmful oils to the sensitive 2026 ecosystem.
Even if you don't plan to "swim," bring a mask or goggles; our clients, travelers, and our agency suggest that looking vertically into the crevices of the pool reveals a hidden world of spaghetti worms and vibrant snails that you would otherwise miss.
If conditions are too rough for the pool (rare), trust Kat’s alternative route; she has several vertical "magical" backups nearby that offer equally stunning beauty without the risk of heavy ocean swells.
The lighting and water levels change vertically throughout the 2026 season.
Park near the porta-potty at Waiakahi'ula Beach Park; you will then follow the guide's car.
No, you must have your own vehicle to drive to the trailhead.
Strictly 7 years and older; it is not suitable for young children or infants.
Surprisingly, no; there are very few mosquitoes or ticks along this specific coastal route.
The pool features both shallow sections (1-3 ft.) and deeper areas (3-5 ft.).
