What time is check in and how long is a whale shark snorkeling day?

What are the in water rules for group size, approach, and time per drop?

Entries are limited to small pairs with a guide to prevent crowding. Maintain respectful distance, never touch, and swim alongside the animal’s path rather than in front. Time per drop is brief and repeated so everyone enjoys calm turns.

Whale shark snorkeling follows strict rules: small pairs enter with a guide, no touching or blocking the animal, and limited time per drop. You slide in ahead of the shark’s path, swim calmly alongside at the surface, then clear space for the next team. These habits keep encounters respectful for both animals and guests.

Pack a long sleeve rash guard, hat, sunglasses with strap, and reef safe sunscreen for exposed areas. Bring a small dry bag, towel, and a light cover up for the ride home. A reusable bottle and motion comfort items are smart additions.

Whale shark days mean strong sun and open water, so long sleeve rash guards, hats with chin straps, polarized sunglasses, and reef safe sunscreen are essential.

How do you choose the search area and coordinate with spotter boats?

We use recent sightings, sea surface conditions, and captain reports to target the most active zone. Licensed boats share updates by radio and, when available, spotter aircraft help locate surface feeding. This network keeps search time short and in water time long.

Finding whale sharks relies on a mix of recent reports, spotter eyes, and radio coordination between licensed boats. Captains choose search lines based on currents and past sightings, then adjust when new information comes in. This cooperation helps everyone spend more time with animals and less time scanning empty water.

Are there age or swim guidelines for kids on whale shark trips?

Children should be confident surface swimmers who are happy floating in a vest and breathing calmly through a snorkel. An adult must accompany each child in the water. If a child is unsure, consider a reef snorkel first to build confidence.

Whale shark trips happen far offshore in open sea, so children need to be confident surface swimmers who are comfortable with masks, snorkels, and boat motion. Parents ride in the same boat and often in the same rotation, helping younger guests feel secure. Briefings emphasize realistic expectations, rest, and optional pauses if anyone feels overwhelmed.

How do you manage seasickness planning for the open water crossing?

We recommend taking any motion medication the night before so it is fully active. Choose a shady spot, keep your eyes on the horizon, and sip water during the run. Let the crew know if you are sensitive so we can help with placement and airflow.

The ride to the whale shark area can be choppy, so advance motion sickness planning is important. Guests who are prone to seasickness are encouraged to talk with a doctor or pharmacist about suitable medication and to take it before boarding. Light breakfasts, hydration, and fresh air on deck also help.

What marine life is sometimes seen along with whale sharks in season?

Look for manta rays, dolphins, jacks, and bonito working the same bait. Sea turtles are common closer to the reef on the return. Birds circling are often the first clue that life is stacked up.

While whale sharks are the focus, other seasonal visitors sometimes appear in the same offshore areas. Mantas, dolphins, jacks, and bonito schools may pass through, and sea birds often circle overhead. Guides point out these encounters when they happen, but they are always treated as bonus sightings.

Do you run private whale shark charters for families or small groups?

Yes, private charters are available and include custom pacing, flexible turns, and extra coaching. Photographers appreciate slower approaches and repeated drops for cleaner shots. Families enjoy space, shade, and easy deck logistics.

Private whale shark charters give families and small groups their own boat, captain, and guide team within the same safety rules. You can adjust pacing, rotations, and reef stops to your group’s comfort. The encounter guidelines, conservation practices, and port decisions remain identical to shared trips.

How do weather and port calls impact whale shark departures?

We follow Harbor Master guidance for safety, and closures can delay or reschedule departures. Wind and sea state are reviewed the evening before and again at dawn. If the port restricts departures, we offer the next best plan and notify you by WhatsApp.

Whale shark departures depend on both marine forecasts and Harbor Master approvals. If winds, swell, or storms make the offshore area unsafe, trips can be delayed, rerouted, or cancelled. Manta communicates changes by message as early as possible so you can adjust plans without rushing.

Can I add a reef snorkel after the whale shark segment if conditions allow?

Yes, time and sea state permitting, a shallow reef stop can be added on the return. It offers warm color and easy photos after the blue water action. Your captain confirms feasibility on the day.

When time, sea state, and port rules allow, boats may stop at a shallow reef or sandbar after the whale shark segment for a short snorkel. These areas offer clear water, calmer motion, and relaxed swimming. The captain always prioritizes safety and timing over squeezing in extra stops.

What conservation practices do you follow to protect whale sharks?

We limit group size in the water, forbid touching, and never block a shark’s path. Sunscreen must be reef safe and all trash stays secured on board. Captains coordinate spacing so animals feed without pressure.

Conservation guidelines forbid touching, riding, or feeding whale sharks and limit boats and swimmers in the area. Engines idle or shut down during drops, and crews avoid cutting across an animal’s path. Briefings stress that photos and memories should leave no trace in the water behind you.
