Whale Watching (Dec - Apr)

If you're lucky, you'll be able to see the whales play offshore just by standing on the coast and looking out to the ocean! For a more reliable experience, book a whale watching tour, where you'll sail out into the water with an experienced captain and crew to find whales and observe them from a a close, but respectable, distance.
Day Sailing Cruise from Hilo

Enjoy these relaxing, scenic boat cruises around the beautiful Hilo coastline. A relatively new area of land, the beautiful, lush environment of Hilo's coast can be only seen from a boat, as there are few beaches in the area. Perfect for a day out, these small group tours are a great way to unwind while familiarizing yourself with the Big Island's stunning coast.
