Conservation-led. Ocean Calling guests never chase, touch or bait animals.

Why Moderate? The manta snorkel is at night, in open water from a boat, and the whale watch is a morning on a small boat, where the sea can move.

Who it is for. Beginners, solo travellers, couples and friends who love the ocean, no diving needed. You should be happy snorkelling in open water from a boat, also at night, and excited to meet wild animals on their terms.

What you do

Manta rays at night, whales from the boat and the turtles of the Kona coast. Sightings are never promised. Each caption says where the photo was taken.

New or a little nervous?

Your first day, step by step

  1. Day 1 · Welcome to Kona: Rocío meets you at Kona airport (KOA) and takes you to our hotel on the beach in Kailua-Kona. You settle in, then we meet for a short talk about the week and the animals.
  2. Your guide explains the plan and the signals before anything starts in the water.
  3. You choose your pace. You can pause, rest or skip any activity, at any moment, with no pressure to continue.
  4. Nobody chases, touches or baits an animal. The animals decide whether they come close.

Questions beginners ask

What if I feel nervous in the water?
That is very normal, and you are welcome here. Activities are adapted to your level and comfort. Tell your guide or Rocío, and you can pause, rest or skip an activity at any moment.
What if I cannot clear my ears?
Equalising is taught in small steps by your instructor, and nobody is asked to push through. If your ears will not clear, you rest, come up or skip that dive or descent.
Will I hold the group back?
Groups are small (six guests at most, and some trips are four), so the pace follows the group and nobody is rushed. Tell Rocío your level before you book, and she will tell you honestly if a trip fits.
Do I need to be fit or experienced?
Each trip page shows its level and what it asks of you. If you are not sure, take our short Is it for me? questions, or read the booking FAQ.

Highlights

  • Float above manta rays at night off the Kona coast, where the manta night snorkel runs all year.
  • A humpback whale watch in the middle of the whale season (about mid-December to the end of March), from a small boat with a hydrophone to listen to them.
  • A morning snorkel in Kealakekua Bay, with its reef and green sea turtles.
  • A culture day at Puʻuhonua o Hōnaunau National Historical Park with a local guide.
  • One hotel on the beach in Kailua-Kona for the whole week, so you unpack once.
  • Breakfast every day, and a conservation talk about the animals we meet.
  • A small group of six at most, hosted by Rocío from your first question to the last day.
  • Wildlife first: no chasing, no touching, no feeding, and the ocean decides what happens.

The rhythm of your days

  1. Day 1 · Welcome to Kona: Rocío meets you at Kona airport (KOA) and takes you to our hotel on the beach in Kailua-Kona. You settle in, then we meet for a short talk about the week and the animals.

Honest pricing

Why our retreats cost what they cost

  • Six guests at most. One boat and one guide are shared by fewer people, so each guest pays a bigger share and gets real attention.
  • Local guides, paid local wages. We book external local guides and never ask them for discounts.
  • What your price covers. Your room, breakfast, the activities listed on the trip page and card fees. Other meals only where the trip page says so. Flights are not included.
  • Planned by me. I plan every trip myself, and I am with you before, during and after.

Ethics and safety

  • Humpback whales: by United States federal law nobody may approach them within 100 yards (about 90 metres), by boat, kayak or swimming. In Hawaiʻi this is a whale watch from the boat, never a swim.
  • Spinner dolphins: swimming with them or coming within 50 yards (about 45 metres) is illegal, so we never offer a dolphin swim.
  • Manta rays: we float at the surface by the lights and never touch them.
  • Sea turtles: we stay at least 10 feet (3 metres) away and never touch or follow them.
  • Wildlife encounters are unpredictable. Manta snorkelling and whale watching should always follow local regulations and experienced professional guidance.

Practical details

  • Getting there: fly into Kona International Airport (KOA) on Hawaiʻi Island. Rocío meets you, and airport pick-up and drop-off are included.
  • Travel insurance is required. No diving is needed on this retreat.
  • Payment plan: you pay a 30% deposit when Rocío confirms your place, then monthly payments charged automatically, with the balance due 60 days before the trip.
  • Every activity is optional. You can rest any day.
  • The order of the days can change with the weather and the sea. Rocío will always tell you why.
Why we choose slower boats

Speed is one of the simplest things a boat captain controls, and it matters a lot to the animals we visit. Research from many oceans shows the same pattern: a slower boat is less likely to hit a whale, turtle or manatee, gives animals time to move away, and makes less noise under the water.

Slower ships kill fewer whales

A study of 47 recorded ship strikes on large whales found the chance of a deadly injury was 21 per cent at 8.6 knots but 79 per cent at 15 knots. Below 11.8 knots, a strike is more likely to be survived than not.

Vanderlaan & Taggart, 2007, Vessel collisions with whales: the probability of lethal injury based on vessel speed (Marine Mammal Science)

A 10 knot limit works for right whales

Since 2008, the United States has required vessels 65 feet (about 20 metres) or longer to travel at 10 knots or less in set areas and seasons along the East Coast, to protect North Atlantic right whales. A later study estimated these limits cut the risk of deadly ship strikes by 80 to 90 per cent.

Conn & Silber, 2013, Vessel speed restrictions reduce risk of collision-related mortality for North Atlantic right whales (Ecosphere); NOAA Fisheries, Reducing vessel strikes to North Atlantic right whales

Turtles cannot escape fast boats

In Moreton Bay, Queensland, Australia, researchers watched 1,890 green turtle encounters. 60 per cent of turtles moved away from a boat going 4 km/h, but only 22 per cent at 11 km/h and 4 per cent at 19 km/h.

Hazel, Lawler, Marsh & Robson, 2007, Vessel speed increases collision risk for the green turtle Chelonia mydas (Endangered Species Research)

Slow zones save manatees

In Sykes Creek and the Barge Canal on Merritt Island, Florida, eight manatees were killed by boats in the 42 months before year-round slow speed was enforced. In the 42 months after, only one was killed.

Laist & Shaw, 2006, Preliminary evidence that boat speed restrictions reduce deaths of Florida manatees (Marine Mammal Science)

Faster boats are louder

Recordings of 1,582 ships in Haro Strait, between Washington State and British Columbia, showed that most ships get about 1 decibel louder for every extra knot of speed. This noise reaches the high sounds that killer whales use to find food.

Veirs, Veirs & Wood, 2016, Ship noise extends to frequencies used for echolocation by endangered killer whales (PeerJ)

Going slow gives whales quiet time to feed

When ships in Haro Strait were asked to slow to 11 knots, underwater noise fell by 2.5 decibels, about 44 per cent less sound energy. Scientists estimated this cut the feeding time killer whales lose to noise by 22 per cent.

Questions

Will we see manta rays and whales?
No one can promise that. The manta night snorkel runs all year, and February is inside the humpback season (about mid-December to the end of March), but the animals are wild and they decide.
Can I swim with the whales?
No. In Hawaiʻi it is against federal law to approach humpback whales closer than 100 yards, also by swimming. We watch them from the boat and listen to them with a hydrophone.
Do I need to be a strong swimmer?
No diving is needed. You should be at ease snorkelling in open water from a boat, also at night with the mantas.
How much does it cost?
USD 5,270 per person in a twin room, for two guests booking together, with a 30% deposit (USD 1,580) to book. A private room is USD 6,600 (deposit USD 1,980). International flights are not included.
How does the payment plan work?
A 30% deposit when Rocío confirms your place, then monthly payments charged automatically, with the balance due 60 days before the trip.
Can I have a room of my own?
Yes, a single room is on request. Or you share a twin room with one other guest of the group, with your own bed.
What is included?
Six nights in the hotel, breakfast every day, airport transfers and transport, the manta night snorkel, the whale watch, the Kealakekua Bay snorkel, the culture day with a local guide, the conservation talk and tips. Flights, travel insurance, lunches, dinners and drinks are not included.
Which meals are included?
Breakfast every day. Lunch and dinner are your own choice, so you can eat what suits you and manage allergies and diets. Drinks are not included.
Can I come alone?
Yes. Come alone, with a partner or with a friend. The small group and the days on the water tend to take care of the rest.
How do I book?
Click Book your place and choose your room on WeTravel. You pay the deposit securely there, and Rocío then welcomes you personally, with the payment plan: a 30% deposit, then monthly payments, balance 60 days before the trip.
