What Travellers Say
Reviews Summary
Visitors praise Keaiwa Heiau for its stunning panoramic views and diverse forest scenery, offering great value for the effort. The historical heiau site adds cultural depth. However, the campground's rustic facilities, uneven terrain, and potential for muddy trails after rain are noted drawbacks.
"Low level difficulty, took our 4, almost 5 yr old and a small dog and we did it in about 3 hours with lots of snack and drink stops. I’d say one of my absolute favorite trail hikes when it comes to the views you get for the effort you put in. A couple spots can get muddy if it’s rained, there’s roots and uneven ground but still doable if it’s a rainy day. There are options to do the side hikes to see the waterfall or accidentally go onto a marine base(don’t do it, 1000$ fine easy). The view of pearl harbor isn’t great but still scenic. The biome changes from native large red trees, To strawberry guava trees which are invasive and are outcompeting the local trees, to then the pale white eucalyptus with the incredibly beautiful colors in the bark to then Norfolk pine to back to the red soil and large native Luhas. Such immense beauty."

"It's pretty difficult to find more information about Keaīwa Heiau Campground and it doesn't have its own pin on Google Maps therefore I'll try to put some information together here. If you go to Honolulu and you're planning to camp close to the city, this is the spot for you. Camping here is inexpensive, I think $30 per party per night for non-Hawaiian residents. The Campground is in 300m (1000ft elevation). 10 camping spots (one above the parking lot, three in the forest, 6 on the grass lawn). None of them has flat even ground for the tent. Probably the best and level spot for tent is between sites 4B and 3B. Stairs to the restrooms are not on the best shape, steep and narrow. Facilities old, missing mirror, soap, shower head, door for washroom / toilet. There is no power outlet. We camped by ourselves, there was no one else which made the experience little weird. What surprised us is the amount of the cats, they're everywhere, maybe 70 of them. In the morning chickens and roosters."

"This main loop in this Area has nicely paved trails that are easy to follow with some aesthetic viewpoints. I believe there are remnants of a crash-landed bomber along the path too (see pictures).
There is also a breadfruit tree by the (I believe to be restored) temple."
