The bay is a deep (approx 40 metres in the middle) and large natural bay, with one of the longest inlets in southwest Ireland, bordered on the north by Beara Peninsula, which separates Bantry Bay from Kenmare Bay. The southern boundary is Sheep's Head Peninsula, separating Bantry Bay from Dunmanus Bay. The main islands in the bay are Bere Island and Whiddy Island. Bere Island is located near the entrance to the bay. On the north side of the island is Berehaven Harbour and Castletown Bearhaven port. The town of Rerrin is the largest settlement on the island. The village of Ballynakilla is also located there. Whiddy Island is at the head of the bay near the south shore.
