Yeah, Miri do have a Hawaii Beach. I don't know why it is called like that. We been to Hawaii Beach after the trip to Batu Niah.
It is not easy to spot this beach. It is quite hidden and there is no signboard saying this is Hawaii Beach. You need to find it for yourself. It is after the Luak Esplanade.
One tips to find this place is, it is near a Prawn Breeding Farm. Just keep driving from Luak Esplanade upwards until you see a signboard for the Prawn Breeding Farm at you left. Meaning the Beach is at your right.
Little people knows about this place, and the distance is quite far too. So, the beach is quite empty when we were there.
Here are some random shots. Lazy to elaborate more.
