A little more about Bantry Bay
I'm going backwards but I did not get a chance to fill in a few details about Bantry Bay. The Bay itself is lovely with high hills all around catching light in interesting ways. Aside from Adrigole and Glengarriff, there's a lovely marina on Bere Island servicing mostly sailing vessels. The approach to the marina is now marked so access is straightforward. Castletownbere on the other hand, as well as many small harbours along the shores, cater more to fishing vessels.
There is a huge fish farm on the northern side of the lighthouse taking up almost all of the open water there. Many mussels farms dot the harbours including Adrigole and Glengarriff. Care must be taken when navigating these waters in low visibility.
Bantry is more of a larger town and Whiddy Island has a huge oil tank installation. We did not stop in.
