Waioka Pond

Past Hāmoa Beach

Marketed in some guidebooks as the "Venus Pool," Waioka is a tidal pool where a stream meets the sea past Hāmoa. It sits behind private land, has taken lives in flash floods, and carries ongoing water-quality warnings. This page explains why it's best left off your itinerary.

⛔ SKIP / NO ACCESS · NO LEGAL ACCESS · DANGEROUS CONDITIONS

At a glance

Flash floods: Fatal Accidents — The pool sits in a stream corridor that floods fast when it rains in the mountains, even under clear skies at the coast. Swimmers have been swept into the ocean and drowned here.
Access & land: Private land, contested fee — The established trail crosses private land. A roadside vendor charges to park nearby, but the landowner has not granted public access — the warning sign is about liability, not permission.
Water quality: Bacteria warnings — Testing has repeatedly found elevated fecal bacteria in the pool, with levels that swing unpredictably. It's not a clean swimming hole.

About Waioka Pond

Waioka Pond lies past Hāmoa Beach, where a stream pools just before reaching the ocean behind a barrier of cobble and sea stacks. The name comes from a longer Hawaiian word (Waioaoaka) which means "open mouth of fresh water." The "Venus Pool" label is yet another example of modern tourism rebranding.

The most serious hazard is flash flooding. The pool sits at the bottom of a corridor fed by streams high on the mountain, and rain falling far upslope can send a surge of water down with little warning, even when the coast is sunny. Swimmers have been swept out of the pond and into the open ocean here. There are several youtube videos documenting close calls (see below).

There are land and legal reasons to stay away as well. While the pond and shoreline are on state land, the established access trail runs across private property. A vendor near the road charges to park, but that fee does not represent the landowner's permission to cross, and the warning sign at the fence exists to limit liability after repeated injuries and deaths, not to invite visitors.

Good to know

This is an avoid stop. The pool floods without warning, offers no escape route, and has killed swimmers. The approach is dangerously slippery, the water carries bacteria warnings, and access crosses private land. The indpendent roadside vendor selling parking does not grant legal access.

Frequently Asked Questions

Is Waioka Pond (Venus Pool) safe to visit?
No. It sits in a flash-flood corridor that has swept swimmers into the ocean and caused deaths, the trail down is slippery and steep, the water has repeatedly tested high for bacteria, and access crosses private land. It's a place to avoid.
Can you legally access Waioka Pond?
The established trail crosses private property. A nearby vendor charges to park, but the landowner has not granted public access, and the roadside warning sign is about limiting liability rather than permitting entry. Treat it as off-limits.
Why is Waioka Pond dangerous?
Flash floods are the biggest risk — rain in the mountains can surge down the stream corridor with no warning, even under clear skies, and has drowned swimmers. Once you're in the pool there is no where to escape a flood. Add slippery cliffs, cliff-jumping injuries into shallow water, and recurring bacteria warnings, and the hazards are severe.
Why is it referred to as Venus Pool?
Waioka is the Hawaiian name, a localized contraction of its older, traditional name: Waioaoaka which means "open mouth of fresh water." "Venus Pool" was a name popularized by guidebooks which operate on a formula of "uncovering" hidden attractions. To make an unlabeled, remote stream mouth appeal to the mass public, they applied sensationalized (Greco-Roman in this case) imagery. Rebranding it after the goddess of beauty transformed a raw, rugged natural hazard zone into a consumable, romanticized attraction. There are many examples of this throughout the islands. Today we appreciate the importance and value of using historic place names.
Where can I swim safely near Waioka Pond?
Hāmoa Beach, a short distance back toward Hāna, is public and far safer for swimming on calm days. It's the responsible alternative to the risks at Waioka.
