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.
Big Island Whale Watch Tours
See whales on the best Big Island whale watching tours this winter, and watch as the Pacific humpback whales rest and play after traveling from Alaska to Hawaii. December and April is whale watching season on the Big Island, and the ocean becomes the winter home for humpback whales and their calves that are born in the island's warm waters, and with whale watching cruises, boat rides, and sails departing from Kona, Waikoloa, and Hilo, there is a whale watching experience perfect for everyone.
Traditional Hawaiian Sailing Canoe
Get a uniquely Hawaiian experience in these sailing tours that put you in a vessel the islands are famous for. Whether in an outrigger canoe or a double-hulled sailing raft, these ocean tours will allow you to experience the waters of Hawaii the same way the first Polynesian settlers did.
