There's always one spot that shows up first in every search — easy parking, a low wall to sit on, a crowd that starts gathering an hour before the sun even gets close to the water. It's popular for a reason. It's also not the only view on the island.
Walk five minutes past it, away from the crowd, and you'll usually find a quieter stretch with the same sky and none of the noise. No one clapping when the sun disappears. No one blocking your view with a phone held up for a photo they'll post and never look at again.
The locals' spots tend to be simpler — a bench nobody put there officially, a rock ledge, the end of a road that just happens to face west. Nothing marked, nothing maintained, just a good angle someone found once and kept coming back to.
Bring your own chair. Bring someone you actually want to sit with. The sun does the same thing every night whether there's an audience or not.
