This is a fairly easy hike. The path is paved and wide. There are many areas on the way to the top where you can sit and rest if you get tired.
Most of the places where you can sit also have spectacular views of the ocean so you can whale watch while you catch your breath. We saw over a dozen whales breach out of the water and WHAP back down on the surface.
We had a great group of friends with us which always makes it so much more fun. Behind us you can see Koko Head Crater which is an extinct volcano.
When you reach the top, there are fenced in "pill boxes" from which you can best view the ocean and the lighthouse. Taking Ben is like taking a toddler along. He climbs over the safety rails and rambles along like a mountain goat among the rocks. I always fuss and tell him I know he's safe, and I'm not worried about him falling, but the younger kids always copy him, and they might not be safe and could get hurt.
But really, I'm worried about him falling.
From the top you can see not only Makapu'u Lighthouse and Koko Head Crater but also part of the Koolau Mountain Range and Rabbit Island.
And if you look closely, you might spot the Karate Kid holding a can of Arizona Tea.
