At the top there is a sign saying "End of Trail. Do not go beyond this sign, please turn back." I think this is due to the nature of the trail changing significantly from enclosed and protected with a good and obvious path, to exposed, windy with significant drops from narrow ridges if continuing onto Pu'u'okona. Everyone has their own differing levels of experience and comfort with exposure, but ensure you have good trail shoes if continuing.

Tantalus Lookout allows you to see all the way to Diamond Head in the east, and to Honolulu International Airport and Pearl Harbor in the west. This spot is particularly popular at sunset due to the west facing view. Once you get to the upper parking lot, you will have to push your bike a very short distance to get to the end of the lookout area.

But the great view of the valley and the ocean in front of you, will make you forget about everybody else and just enjoy the moment.
