Great views
As you pass the halfway point on the way up you will start hiking north toward the lighthouse. You will see more cacti along the path and if you are hiking during whale migration season (November to May), you may see humpback whales swimming between Oahu and Moloka'i and Lana'i.
On a clear day you can see all the way to Moloka'i and Lana'i. Continue along the path until you reach the top.
