Cala Belladona is located right in the middle of the stretch between Platja d'Aro and Sant Antoni de Calonge. It's a small cove measuring only 150 metres in length and 30 metres in width, covered with natural large-grain sand. It's a fairly "wild" beach with no summer amenities, with the exception of a seasonal beach café (chiringuito).
The main attraction of the cove lies on its southern side. A tiny isle Belladona Grossa is home to a seagull colony, so do approach with caution—seagulls lay eggs there and may be aggressive to unexpected visitors threatening to disrupt their offspring.
