How many lighthouses exist on Oahu? If you’re just here to find the answer quickly – there are six. If you want to go deeper than that though – read on.

Most people can only list one or two of the lighthouses on Oahu. Diamond Head Lighthouse is an obvious one and the one at Makapu’u Point is another that people will see if they are driving around the island. Both of them are special and beautiful.

The Lighthouse as Diamond Head is the home of the Coast Guard Admiral in charge of the Mid-Pacific Region. It is beloved by Oahu residents and has a beautiful old antique fresnel lense. It was built in 1899.

Equally loved (but sometimes forgotten because out-of-sight means out-of-mind)is the lighthouse at Makapu’u Point. You won’t see it if you are driving from the south shore up to Waimanalo unless you look backwards as you are going past Sea Life Park – but if you are driving the other direction – you can’t miss it. It was built in 1909 and its hyper-radiant lens is visible for 28 miles – so, for those who are curious and have hiked the Makapu’u point trail and seen the island of Molokai off in the distance – it can be seen with the naked eye from there (22 miles).

Perhaps more loved than both is the Aloha Tower in Honolulu – which most people have no idea is even a lighthouse! It is the oldest lighthouse on Oahu and while it has a clock in it, it was actually built to help guide ships into Honolulu Harbor. It was not a vanity project! The grounds are mostly Hawaii Pacific University but there is a Gordon Bierch Brewery there – so you can grab a beer after you admire the lighthouse.

The other lighthouses are less well known. There is the Kaena Point Lighthouse which is now a collapsed ruin on the westernmost point of Oahu – it has been replaced by a metal tower. The hike to get there is worth it – beautiful easy walk through bird preserves and isolated beaches.

Pyramid Rock on the Marine Corps Base in Kaneohe is the home for another lighthouse – it is not accessible to the public – just like the entire base. It’s too bad because this is one of the most beautiful areas on Oahu.

Finally, there is the lighthouse at Barber’s Point. This lighthouse has a modern lense but an old body, it was built in 1888 and has saved many souls from smashing on the reefs of Oahu. It is an active lighthouse in beautiful surroundings – so beautiful that one of Hawaii’s most popular luau’s is set nearby. It’s off the radar for most visitor’s but is worth the trip if you have a car and some time.
