This walk takes about 45 mins each way. Make sure you take water as it is very undulating and steep in some parts and there is no fresh water when you get there. If you are planning on making a day of it you will need to take everything with you. There are toilets there. From Oct to April you cannot park at the start of the walk but they do offer a shuttle from Hahei beach to the start of the walk which I would recommend taking.
