the places above are all admission free. Beside the transportation fee, you dont have to spend any money.
But, something to note:
>wear proper attire & shoes
>Bring enough water, a little bit snacks if you like (dont throw any rabbish in the parks)
>Umbrella is not a must, but it does rain without letting you know.
>Watch the tide, if you go there at high tide, you wont see anything interesting but water
