Kaniakapupu Ruins - a royal summer home

The Kaniakapupu Ruins are a historical site nestled in the lush forests of Oahu, Hawaii, serving as the former summer palace of King Kamehameha III and offering a glimpse into the island's rich cultural heritage. 🏰🌿

The Kaniakapupu Ruins, better known as King Kamehameha III's Summer Home, is quite a treasure and piece of Hawaiian history that is tucked away on this Nu'uanu Oahu hike!  Unlike other challenging Oahu hiking trails, there really is no hike involved but a light trek to reach the ruins and Luakaha Waterfall.

But be warned that this site is deemed on private land, and is currently being reviewed for barriers for protection from vandals and destruction.

Disclaimer – all Oahu hikes have different challenges and hazards that can be dangerous and may cause injury. Know your fitness and skill level before embarking on any hike.  Stay on trails and obey posted signs. The information on this site is for your reading pleasure only.  Hike at your own risk.


King Kamehameha III Summer Home


King Kamehameha III was a significant figure in Hawaiian history, known for his reign as the longest-serving monarch, his efforts in modernizing Hawaii, and his contributions to the preservation of Hawaiian culture and sovereignty. 👑🌺

This King Kamehameha III Summer Home dates back to 1847.  It was only used for a few decades before being abandoned for unknown reasons, and considered an “old ruin”.

Located in Nu’uanu Valley, up towards the Pali Lookout, this site was used to escape the summer heat.  It was a place where the King could retreat from western influence and discuss governing matters with his people and chiefs.

The Kaniakapupu Ruins are a historic site in Nuuanu Valley, Hawaii, once serving as a summer retreat for Hawaiian royalty and now standing as a captivating reminder of the island's rich cultural heritage. 🏰🌿

One recorded event stated that over 10,000 Hawaiians gathered here for an entertaining luau.  Walk the area and it’s hard to imagine how so many people could fit in this dense area.  Other records show King Kamehameha I resting with his warriors in this area, during his conquest of Oahu.


Oahu hike to Kaniakapupu Ruins


Unfortunately, due to recent vandalism, and out of respect for this unsupervised historical site, we have decided to remove some of the directions to help slow down the activity surrounding these ruins.

If you know the way, and are able to find it, we ask that you enter with respect.  Do not remove or alter any of the rocks in this area, do not climb or deface what remains of this structure.  It seems like common sense, but some folks need a reminder –Mahalo!

With no real hike involved getting to the Kaniakapupu Ruins, it still can be adventurous getting there!  There is no dedicated parking area, no marked Oahu hiking trails, nor are there many hikers in the area.

The entrance to the Kaniakapupu Ruins is a serene and scenic path that leads visitors through a lush forest, immersing them in the natural beauty of the surroundings before reaching the captivating remains of the historic site. 🌳🏰

Your journey starts once you enter a small tunnel opening into the dense bamboo forest.  The opening is small but distinct…but if you don't know where it is, it can seem impossible to find!

The Kaniakapupu Ruins Trail is a picturesque hiking trail that winds through the dense foliage of Nuuanu Valley, offering glimpses of cascading waterfalls, serene streams, and ultimately leading to the fascinating ruins of the ancient Hawaiian summer palace. 🌿🚶‍♂️

The bamboo tunnel trail starts off dense and covered.  Stay straight on the trail, and climb over a large fallen log that blocks the pathway.  Turn left  shortly after onto a small trail opening that travels upward.

The Kaniakapupu Ruins Stream flows gently through the surrounding forest, adding a tranquil touch to the enchanting atmosphere of the historic site and providing a serene backdrop for visitors to enjoy. 🌿🌊

If you remain straight on the hiking trail, you will encounter a neat small stream bed at the end.  It's located not too far from the fallen log, if you decide to check it out.

Continue traveling on the trail, once you turn up from the main trail, for about another 100 yards.  You know you’re close when you come across an old rock wall, which marks the beginning boundary for the Kaniakapupu site.

Just a little farther up and you will see the remains of King Kemehameha III’s summer home in a clearing.

The Kaniakapupu Path is a scenic and well-maintained trail that winds through the lush Hawaiian forest, offering hikers a peaceful and immersive experience as they explore the natural beauty of the area surrounding the historic ruins. 🌳🚶‍♀️

Please respect the Kaniakapupu Ruins and the surrounding area while visiting!  It is a privilege to visit this historical site without supervision or barricades.  Do not pick up or remove rocks from the area, climb or stand on any parts of the structure, or deface anything on the grounds -consider it taboo and bad luck to do so!


Kaniakapupu Ruins


The Kaniakapupu Ruins are a captivating and historically significant site nestled in the heart of the Hawaiian forest, showcasing the remains of a royal summer palace and offering visitors a glimpse into the rich cultural heritage of Hawaii. 🌿🏰

Walking towards the structure you will find an ancient rock pathway that was constructed along with it.

The Kaniakapupu Ruins are a fascinating and secluded archaeological site in Hawaii, once serving as a summer retreat for Hawaiian royalty and now standing as a testament to the rich history and cultural heritage of the islands. 🌿🏰

The structure is a small single story, 3-tiered stone structure that was constructed with western influence, and the guidance of the Hawaiians, such as slightly off centered windows that were put in place to ward off the Night Marchers.

The grass roof is long gone, but a few walls remain in place along with the main doorway entrance, and a window with a beautiful view.

The Kaniakapupu Kitchen is a historic structure within the Kaniakapupu Ruins, believed to have served as a gathering and cooking area for Hawaiian royalty, providing a glimpse into the culinary traditions of the past. 🍳🏰

Alongside the impressive Kaniakapupu Ruins is the “kitchen area”, which also comprises what looks to be a large elevated fire pit made out of large rocks.  Coral reef was melted down is this area, to create a mortar for the rock walls.

This historical site, sacred or not, is one of the most impressive forgotten old structures on Oahu!  It’s a simple ruin in an undisturbed area, yet with a strong presence that you can’t help but feel as if standing in the footsteps of ancient Hawaiian warriors, chiefs, and kings!


Getting There


As you can see from the picture, it's located somewhere off the old Pali Road...after that you're on your own.

The Old Pali Road is a scenic and historic route in Hawaii that winds through lush forests and offers breathtaking views of the island, providing a glimpse into the past and a memorable driving experience. 🌳🚗

Due to large activity and vandalism surrounding the ruins, we have decided to remove the directions in this section.  If you know the way, or are able to find it, please enter with respect!

If you do not know how to get there, it is not recommended to try on your own and wander aimlessly through the dense brush. You could easily get lost or hurt.
