Went prior to the lighthouse opening again March 2016. Lots of wind but good views along the way.

Path is paved. Also more of a walk and a great place for a nice walk with your dog. Beautiful views. There are also numerous paths that break off from the paved path.

More a walk than a hike. The view is awesome and totally worth it.
If you want to add some challenge, make a detour to Makapu'u Tidepools.

very easy paved the whole way
