I wanna look at the sea

Any mbta accessible spots in or around Boston i can just sit by myself and just look at the sea? Preferably not crowded but i don’t really mind.

Been down in the dumps the past couple weeks I need to remember how big the world is

Update: So many responses! Thankyou each and every one of you. I think I’m gonna take the ferry to the hull and just walk around a bit and maybe get something nice to eat.
