Our Review: Hilo Ocean Adventures
Hilo Ocean Adventures is the largest tour operator on the Big Island by sheer volume — 32 tours covering everything from scuba diving to kayaking to deep-sea fishing to waterfall cruises. The average quality score of 74.0/100 reflects that breadth: the catalog includes premium guided experiences alongside basic gear rentals that pull the number down. The guided tours themselves are considerably stronger than the average suggests.
The top tier is impressive. The Beach Snorkel - Sea Turtle Lagoon and Black Sand Beach leads at 93/100, offering a guided snorkeling experience at one of Hilo's most unique coastal sites. Discover Scuba Diving and the 2 Tank Shore Dive at Leleiwi Beach both score 91/100 — Leleiwi is a protected bay with some of the best shore diving conditions on the island's east side. The Royal Humpback Whale Experience (87/100) is the only quality whale watch operating out of Hilo, which makes it essential for east-side visitors during season.
Their kayak program is a hidden strength. The Hilo Bay & Coconut Island Adventure and Wailoa River to King Kamehameha Statue Adventure both score 84/100, offering guided paddles through culturally significant waterways that most Kona-focused operators ignore entirely. The Myths & Legends Waterfall Adventure (81/100) kayak tour adds a waterfall component that plays to Hilo's rainy-side geography.
The Cliffs of Hawaiʻi Onomea Waterfall Cruise (82/100) is another unique offering — a boat tour along the dramatic Hamakua Coast that's impossible to replicate from the Kona side. The bottom of the catalog is populated with gear rentals (surfboards, kayaks, snorkel gear, SUP boards) that score in the 55-64 range, which is expected for rental-only products.
Who This Operator Is Best For
Anyone staying on the Big Island's east side. If you're in Hilo or visiting Hawaiʻi Volcanoes National Park, Hilo Ocean Adventures is essentially your only full-service ocean activities provider. Their guided kayak tours and shore dives at Leleiwi Beach are the standouts, and the waterfall cruise along the Hamakua Coast is something you can't get anywhere else on the island.

Trades are breezy right now with scattered showers on the windward side and mountains; the leeward coast stays mostly dry. Tomorrow stays breezy with the same pattern.
A tropical disturbance southeast of the islands is likely to become a tropical storm by mid-week and approach the state Thursday through Saturday. The exact track is still uncertain. If it comes closer, expect heavier rain over a longer stretch; if it stays farther out, impacts will be shorter and lighter. Winds will increase late this week, with potential gusts over 70 miles per hour on the highest summits.
Plan your leeward beach time and snorkeling for today through Tuesday. Save summit drives and offshore water sports for after Saturday, and check updates daily as this develops.
