We took the opportunity to go snorkeling at the Captain Cook monument. The Captain Cook monument stands on a small plot of British land in Hawaii. It overlooks a marine preserve. Access to the bay is limited and hence the fishes are tame and plentiful. We often use the Fair-Wind organization (https://www.fair-wind.com/) to go there on their boat named Fairwind.
We had Natalie and Niah with us and saw the usual fish as well as an octopus (no picture) and two baby sharks (white-tip sharks?) resting in a rock cave.
It was just great to be out there and to snorkel around.
