A-Bay Unfurled: Sailing, Snorkeling and Whales off the Kohala Coast
Sunrise whales, turtle reefs and sunset sails — everything the Kohala Coast does best.
Anaehoʻomalu Bay wakes before the sun. Palm crowns silhouette the pale arc of sand and the reef sits like a hesitant promise a few dozen yards offshore — a stepped garden of coral and shadow where green sea turtles come to graze. Early light gives the lava fingers that frame the bay a slow-burn bronze, and the ocean feels like an invitation rather than a challenge. Walk to the water and you’ll find footprints that fade as the tide laces them away; board a catamaran and the horizon opens like a map of possibility. On the Big Island’s Kohala Coast, locally called A‑Bay, the day divides into clear pleasures: snorkeling over coral gardens, late‑afternoon sails that flirt with the green flash, and winter mornings when humpback whales punctuate the surface with a lunging blow.
Trail Wisdom
Beach‑load boarding
Many charters at A‑Bay use a tender or require a short wade from the sand — expect barefoot entry and bring reef shoes you can leave on the boat.
Use reef‑safe sunscreen
Choose mineral or Hawaii‑approved reef‑safe sunscreen and apply 20 minutes before water entry to protect coral and comply with local guidelines.
Book morning for whales
Early mornings are generally the calmest for whale watching and photography; book a ‘Wake Up With the Whales’ cruise if traveling in winter.
Respect marine life
Do not touch or feed turtles or corals; stay clear of resting animals and follow crew distance rules for whales.

Conservation Note
Operators emphasize reef‑safe practices and maintain no‑touch policies for turtles and coral; guests are asked to use mineral sunscreens, avoid single‑use plastics and follow crew briefings.
The Kohala Coast holds ancient Hawaiian coastal settlements and fishponds; the shoreline around A‑Bay has been used for fishing and canoe landings for generations.
Seasonal Guide
spring
Best for: Early-season whale sightings, Calming seas for snorkeling, Milder trade winds
Challenges: Occasional rain showers, Variable water temps
Spring bridges high winter whale activity and clearer, warmer water — a sweet spot for both whale watching and comfortable snorkeling.
summer
Best for: Warm, clear water, Vibrant reef life, Calmer seas ideal for beginners
Challenges: Stronger sun and UV exposure, Bigger crowds at peak vacation times
Summer delivers the warmest water and excellent visibility for snorkel sails; bring sun protection and schedule early to avoid crowds.
fall
Best for: Fewer crowds, Good snorkeling conditions, Pleasant temperatures
Challenges: Occasional Kona storms from the south, Less consistent whale activity
Fall can be a quieter time with steady snorkeling conditions, though weather can be less predictable than mid‑summer.
winter
Best for: Peak humpback whale migrations, Dramatic ocean life displays, Cooler mornings
Challenges: Choppier seas on some days, Lower water temperatures for snorkelers
Winter is whale season — book early-morning cruises for the best chance to see humpbacks in transit and breach.
Photographer's Notes
What to Bring
Reef‑safe sunscreenEssential
Protects coral and complies with local conservation guidance while preventing sunburn.
Snorkel mask or travel snorkel set
Provided on many tours, but having a well‑fitted mask improves comfort and photos.
Lightweight sun shirt (rashguard)Essential
Blocks UV and dries quickly on deck — more effective than sunscreen alone for long days on the water.
Reef booties or water shoesEssential
Protect feet during beach boarding and when entering rocky shorelines or reef entry points.
Common Questions
When is the best time to see humpback whales at Anaehoʻomalu Bay?
Humpback whale season runs roughly December through April; early‑morning cruises typically have the calmest seas and best viewing conditions.
Do I need to bring my own snorkel gear?
Most snorkel and catamaran tours provide masks, snorkels and fins, though bringing your own mask can improve comfort and fit.
Are boat tours family‑friendly?
Yes — glass‑bottom cruises and shorter turtle sails are designed for families; check age limits and flotation availability when booking.
Can I touch the turtles or coral?
No — it’s illegal and harmful; always keep distance from wildlife and avoid standing on or touching coral.
How do I board a sunset catamaran at A‑Bay?
Many sunset charters load from the beach with a short wade or tender transfer — expect to step into shallow water to board barefoot or with reef shoes.
What should I wear on a snorkel or sunset sail?
Light layers, a rashguard or long sleeve for sun, swimsuit, reef shoes for boarding, sunglasses and a waterproof camera or dry bag.
What to Pack
Reef‑safe sunscreen (protect coral and skin); snorkel mask or set (if you prefer your own fit); water bottle and electrolyte drink (stay hydrated in the sun); reef booties (for boarding and rocky shore entries).
Did You Know
Humpback whales migrate to Hawaiian waters from Alaska each winter (roughly December–April) to breed and calve, making Hawaii one of the most important tropical breeding grounds for the species.
Quick Travel Tips
Book morning trips in winter for whales; pack reef‑safe sunscreen and a sun shirt; arrive 20–30 minutes early for gear fitting; ask about barefoot boarding and tender transfers when reserving.
Local Flavor
Sample local flavors after the water: poke bowls, fresh tropical fruit, macadamia‑crusted fish, and shave ice; look for small, family‑run food stands in Waikoloa for authentic island bites.
Logistics Snapshot
Where to start: Waikoloa (A‑Bay) — beach boarding for many charters; tours range from short glass‑bottom cruises to half‑day snorkel sails with lunch; most operators provide gear; dress casual and bring reef‑safe sunscreen.
Sustainability Note
Choose operators that brief guests on reef etiquette, use reef‑safe products, limit group impact on snorkel sites and practice wildlife‑friendly viewing distances.
