1. Outdoor Theatre, Waimea Valley
Located somewhere in Waimea Valley is this abandoned outdoor theatre, outfitted with wooden benches that are slowly rotting away, and in a picturesque forest. If only you could still visit this beautiful amphitheater to take in a low-key production in a beautiful setting.
2. Waialee Home For Wayward Boys
Located on Oahu's north shore, just blocks away from some of the island's most famous beaches, the Waialee Home for Wayward Boys was in operation from 1906 to 1947. Its residents were sent there for everything from truancy and disobedience to larceny and assault, and the extensive complex could house more than 100 boys. The building pictures was the boy's dormitory, was later part of the Crawford Convalescent Home, and was partially burned in 2002.
3. Marconi Wireless Center
This abandoned building that sits on Makai Ranch was part of the Marconi Wireless Station in World War I, used for communication with other Hawaiian Islands and the Americas. In World War II, the site was used as an air base, and now sits abandoned.
4. Kualoa Sugar Mill
During the height of agriculture on the Hawaiian Islands, sugar mills were common, and many have since fallen into disrepair. One such mill is the Kualoa Sugar Mill, which sits 2.5 miles south of Kaawa. This abandoned sugar refinery on Oahu was opened in the mid-1860s and found little success, closing its doors just thirty years later – perhaps in part due to the fact that, shortly after the mill opened, a young boy fell into a vat of boiling sugar and died due to the severe burns a few days later - or at least that's the rumor.
5. Old Pali Road
Once a bustling highway on the island of Oahu connecting Honolulu to the island’s windward coast, Pali Road is not only said to be haunted, but has since been replaced. Portions of the road still exist, and are easily accessible on foot from the Pali Lookout. Though the trail is technically restricted, it has become a popular hiking destination.
6. Kaniakapupu Ruins
More commonly known as King Kamehameha III’s summer home, the Kaniakapupu Ruins date back to 1847, and were only used for a few decades before being abandoned and reclaimed by nature. The grass roof is long gone, and all that remains are a few walls, the main entrance, a few windows - and lots of crumbling stone.
7. Lyon Arboretum Seismograph Station
Found near the Manoa Falls Trailhead is the Lyon Arboretum Trail, which will take you on a journey through native Hawaiian flora to a beautiful waterfall. Before you reach the falls on the main trail, you will come across an old, rundown, concrete building that was once used as a seismograph station, and is rumored to be haunted.
8. Abandoned Train, Hawaiian Railway Society
Found at the Hawaiian Railway Society in Ewa Beach is this seemingly abandoned train car, slowly withering away in the elements. While I can't track down much information about this place, it is fascinating to see how far transportation has come since the railroad was in its heyday.
