where was magnum pi set

Magnum, P.I. was primarily filmed on the island of Oahu, Hawaii. The Robin Masters’ Nest (the iconic mansion) stood at the real location of 41-505 Kalanianaole Highway, Waimanalo, though that exact estate was demolished in 2018. Other notable shooting sites around Oahu included Makai Pier near Makapuʻu Point, Waimanalo, as well as various locations around Honolulu, including areas like the H-3 viaducts and coastal settings used for helicopter sequences and chase scenes. Over the years, the show used a mix of real Hawaiian locations and set interiors to bring the tropical private investigator world to life.
