This is part 45 of the puzzle series Around the World in Many Days. Each part is solvable on its own.
This is a Slitherlink puzzle. Draw a single continuous loop along grid lines that does not cross itself. Numbers indicate how many sides of the numbered cell are used for the loop. Ignore the grey lines and letters when solving the Slitherlink – those form a background puzzle that helps you find the final answer in the end.
Today I have visited a uniquely beautiful aquatic ecosystem. Unfortunately I was not allowed to dive in, but that may be for the best from a conservation standpoint. Can you guess where I am?
The clock shapes can rotate but not move. Only the ones matching the Slitherlink solution are relevant.
