Castelo de Neptuno is a shallow, round Algarve reef of cratered rock and short troughs that suits slow, controlled diving more than big swimming runs. The compact layout rewards careful trim, a torch for the recesses, and patient macro scanning across sand-framed pockets where small life tends to cluster. It is a strong fit for relaxed training dives on settled days.
