Biggs Hawaii operates out of Waimea on the island of Hawaiʻi and runs marine tours and fishing charters departing from Kawaihae South (Kawaihae South Small Boat Harbor). The company offers a range of guided experiences including manta ray snorkel and sunset tours, whale watching excursions, turtle snorkel and dolphin viewing trips, and private reef and deep-trolling fishing charters.
Guides on Biggs Hawaii tours provide onboard interpretation and wildlife viewing focused on local species: manta rays feeding on plankton, humpback whales (including mothers and calves), sea turtles, spinner dolphins, and abundant reef fish. Fishing trips include light-tackle reef fishing targeting species like rainbow runners and uku, and deeper trolling trips for Mahi Mahi, Ono, and Ulua using professional equipment and crew. Trip durations range from 1.5-hour sunset and whale tours to 2.5–3-hour snorkel trips and 4-hour fishing charters.
Biggs Hawaii positions safety and family accessibility as priorities: several tours are described as family-friendly and manta tours note suitability for children aged 5 and up. The company emphasizes experienced guides and professional crew for guided snorkeling, wildlife viewing, and sportfishing. Departure information, trip durations, and species encounters are provided for each experience so guests can choose the best marine adventure from Waimea and Kawaihae.
