The Pali Puka trail is a short distance, but the trail was much more exposed and challenging to negotiate than the length of path suggests.
The trail is hidden beyond the parking lot at the Nuuanu Pali Lookout and follows along the ridge line of the Koolau mountains. The ridge of these mountains is quite thin in places, and their steep rock faces on the windward side of Oahu are not very inviting.
A "puka" is the hawaiian word for "hole." Appropriately, at the end of this short hike, there is a hole in the ridge where satisfied hikers can enjoy the view over windward Oahu, or look back down the lush and green Nuuanu Valley toward Honolulu.
Oahu is full of invasive species - and some make the island slightly more pleasing to the eye. One such flower is the cup of gold flower which can put out blossoms up to seven inches across while the "cup" can be up to nine inches deep. The flowers grown on vines and tend to grow in the wild, although they were initially brought over from Mexico to be ornamental. Flowers range from a very pale yellow to a dark burnt orange before they wilt.
