You could describe a particularly pretty scene as picturesque. But save it up for a view that's so gorgeous you'd love to have it framed on the wall as a painting.
Picturesque is an adjective used to describe something with strikingly pleasing or vivid qualities — a scene so picture-perfect that you feel an impulse to reach for your camera or double check to make sure it's real. A view of the pristine shoreline on a summer’s day, a grandfather and grandson reading a book together, or a charming old farm cottage could all be called picturesque.
