Lovely views ! But those pretty flowers... yeah, that might just be giant hogweed. It could be native hogweed ( a slightly safer relative). Apart from the height (which you won't know until fully grown) and flowering season (which overlaps right about now...), it's possible to tell by the leaves - giant hogweed is more jagged with pointed leaf tips, native hogweed has broader more rounded leaves.
If it's the giant version the sap is a super-alkaloid. If you brush against it and get any of the sap on your skin, it'll burn like you wouldn't believe, leaving long-lasting blisters, photosensitivity and possible permanent scarring. Get it into your eyes, and it's off to A&E in a big hurry.
It's still pretty, though 😀
