Kaipapa'u Makai is a 2.4 mile lightly trafficked out and back trail located near Honolulu, HI that features beautiful wild flowers. The trail is rated as moderate offers a number of activity options.
A relatively short hike that takes you to 3 bunkers. Great views of north east shoreline. This trails starts off on an access road to a water tank. Turn left at the tank to follow the trail heading into Kaipapa'u Gulch. Turn off right heading up the ridge at the first red dirt opening. If not, the trail will take you to the stream. The trail steeply ascends the ridge through iron wood, and then opens up to christmas berry. Soon you are in a Hau territory. A couple of switchbacks and you ascend higher up the ridge. Look out for the eroded spots. On reaching a large eroded area just past more iron wood, turn right along a narrow ridge heading makai. There are three bunkers at the end of this trail; all belonging to the WW II era. They were once part of the Hawaiian Seacoast Artillery Command established from 1942 to 1946 that had acquired 8 twin gun mounts from the aircraft carriers Lexington and Saratoga to create 4 land batteries and a series of communications bunkers that controlled them. The bunkers at Kaipapa'u were simply known as station M. This is a great lunch spot, where the views span more than 180 degrees.
The trail is a little overgrown, but easy. Only takes about an hour to the top. Be respectful to the residence.
Loved the views. I hiked up with four kids ages 6 to 10, and they did really well. We had to stop for breaks on the way up due to the climb, but the kids made it just fine. The kids enjoyed the bunkers. The trail to #3 isn't the best for young ones, a bit steep and slippery. The bunkers are all pretty close together, so it was easy to split and leave a small group resting at the earlier bunkers while I took the adventurous ones ahead to scout things out.
This was a fairly quick hike, with a view that cannot be beat! The third bunker is a little sketchy to get to so use caution, but the view overlooking Kokololio Beach is incredible.
Super well cleared and marked and only took about 45 up and 25 back. Epic views, awesome windflowers
Never found the bunkers
Fun hike. Moderate difficulty is accurate. Mostly uphill to the bunkers and then downhill back. We accessed the trail off of kawaipuna street. Our group ranged in age from 9 to 40- something's and all could handle the distance and terrain. During cooler months, may be good to wear long pants (or high socks) given growth of brush. Bunkers' view was great - from malaekahana to kaaawa.
Great short hike with beautiful view of the North Shore.
