If you go around the start of the year, you might be lucky enough to see a whale in the distance! While I did not see a whale, I did get to see a group of dolphins. Still waiting on hopefully one day seeing a monk seal or turtle. I was really feeling Geographer that day.
Along the path, you will see many Albatross nests. Hawaii is home to around 99.7% of Albatross. They look pretty cute, huh!
