Legend of the Princess Caves at Waianapanapa State Park, Hana, Maui

Deep in the Mesic Coastal Forest of Hana’s Waianapnapa State Park Lies a small cave filled with a pool of clear cool fresh Water. While the pond is fairly striking and the Cave displays some incredible Rock formation due to the Basalt Lava that formed the pond, There is a legend surrounding the water that elevates this pool to legendary status. Here is the Legend of the Princess Caves at Waianapanapa State Park

Legend of the Princess Caves at Waianapanapa State Park

The Princess Caves

The Princess caves are an example of Hawaii’s Anchialine Pools. These are pools that have no surface connection to the Ocean but instead link to the saltwater via underground passages and filters. This causes these pools to appear on the surface but often remain clear and clean despite no obvious run in or off. Normally a small pool like this with now fresh inlet or outlet would quickly become stagnant and icky, but the princess pool is often crystal clear.

There is a freshwater feed somewhere in the cave and the pool drain via subterranean pathways into the ocean. While the water is fresh it mixes with the saltwater somewhere underground at about sea level.

From the outside, the cave appears little more than a pool with a rock overhand. but once in the water, you can find a low opening that you can duck under (without submerging your head) and access the inner portions of the cave. It is not big in there so do not expect much, just enough room for a small princess to haul out of the water and hide, more on that later.

How to Find the Cave

Trail to Princess Cave

The Cave is easy to find from the Waianapanapa State Park. From the Trailhead that leads down to the Black Sand Beach take a left and follow the trail up past the carpark. The Trail may be marked as closed due to potential rockfall.

The trail is well worn, even when closed as people often ignore the signs and barriers. The trial courts through some really interesting forest with passageways carved in the Hala tree routes and Hibiscus flowers raining down from the treetops. It is very eerie and atmospheric.

At the end of the short trail, there is an impressive cave entrance, with hexagonal patterned lava rocks firing the ceiling and a clear cool pool in the bottom. You can continue on the trail and find another pod but this is shallow and often filled with detritus from the forest canopy.

Exploring the Cave

Entering the Cave

There s a rough natural Rock staircase down to the pool under the overhang. The clear water is very cold but normally it is manageable, and swimming is shocking but not so cold you get the burn. Relaxing in the pool is a nice way to cool off, but the real experience is to enter the cave itself. As you head toward the deepest portion of the pool at the very back of the overhang you should find an opening. Ducking your head under here will grant you access to the cave. Depending on water levels you should be able to enter without fully submerging your head, but care should be taken as you do not want to get stuck underwater.

We advise goggles here, as the ability to see can really help. Always know your limits and don’t try and enter the cave if water levels are so high you have to go fully underwater to get inside. If you cannot easily locate the opening don’t push the matter. It should be east yo find and obvious. If it’s not the pool is too full or you are just looking in the wrong spot. Diving under to find it will not end well.

Inside the cave, there is not really a lot to see. First of all, it is DARK. Without a torch, you may as well just head back out. If your phone is waterproof, you can take this with you (Turn the torch on FIRST) and use this. But remember your phone is quite an expensive and important item, losing it in a cave will not be funny!

Inside the cave, there is a ledge you can pull out onto. It is not a large ledge and only good for perching. As far as long term hiding places go we don’t think the princess made a great choice!

The cave does extend backward but outside of the initial chamber, form which you will be able to see the light of the way out from, you would be insane to explore further. We doubt very much there is anything worth seeing and you will almost certainly be joining Princess Popoalea if you venture any further. Speaking of which, onto the Legend!

The Princess Cave Legend:

Princess Cave Hana

“Once upon a time, a Hawaiian princess named Popoalaea fled from her cruel husband, the chief Kakae. She hid on the ledge just inside the underwater entrance to this cave. A faithful serving maid sat across from her fanning the princess with a feather kahili, a symbol of royalty. Noticing the reflection of the kahili in the water, the chief Kakae discovered Popoalaea’s hiding place and killed her. At certain times of the year, tiny red shrimp appear in the pool, turning the water red. Some say it is a reminder of the blood of the slain princess.”

Sign at the head of the Pool

How true the legend is, is impossible to determine, most of Hawaii’s culture is told through word of mouth or song. But the tale is fairly specific and as we mentioned above there is certainly a ledge in the cave where the princess could sit. Quite why she would need to be fanned in the cold damp atmosphere of the cave is obviously a mystery but if that is the only spurious detail we are willing to forgive.

As for the shrimp and the water running red, the jury for us is still out. There are definitely Red Shrimp in the pool but we have never witnessed them in the numbers needed to turn the pool red. The presence of the shrimp obviously leads to the possibility the tale was made up to explain the shrimp rather than the other way round.

But really we do not care, it is an interesting if unfortunate and bloody tale. And really the pool might not be worth visiting without the tale to make exploring the cave worthwhile. Although the short trail leading to the pool is very interesting and the cave formation pretty striking, it is just a shaded cold pool without the interesting backstory.
