These terms explain how bookings, payments and trip changes work when you arrange a snorkelling or scuba diving trip. We have kept them as clear and practical as possible.
Last updated: 14 August 2026
Sending an enquiry or booking request does not confirm a reservation straight away. We will check availability and your booking is confirmed when we send you written confirmation and any required payment has been received.
The person making the booking must be at least 18 years old and is responsible for the booking on behalf of everyone included in it. If you provide another traveller’s details, please make sure they are happy for you to do so and that they understand these terms.
The amount and currency shown in your written confirmation or invoice are the amount due. Any deposit, balance amount and payment deadline will be explained before you pay.
Please pay by the stated deadline so we can keep the reservation secured. If payment is late, the requested places may be released. Card payments are handled through a secure hosted payment provider, and your bank or card provider may apply its own exchange rate or charge.
Trips are subject to availability, weather, sea conditions, national-park decisions and safe operation. Pickup times, boats, dive or snorkelling sites, routes and schedules may change when reasonably necessary.
We will provide the latest confirmed information available to us and let you know about a significant change as soon as reasonably possible. Please avoid making tightly timed onward travel arrangements around an estimated return time.
Please provide complete and accurate names, contact details, dates, hotel or pickup information and any other details requested for the trip. Scuba bookings may also require certification, recent-dive experience, equipment and insurance information.
Tell us promptly if anything changes. Incorrect or late information can delay confirmation, affect pickup or prevent the relevant trip provider from accepting a traveller.
All scuba diving trips in the National Marine Parks require Advanced Open Water certification or higher. You must also have been diving within the 18 months before departure.
All guests must follow reasonable safety instructions from the captain, crew, guide or dive professional.
Scuba diving insurance is required for all scuba diving trips in the national marine park. Please check your holiday insurance, as not all insurance policies cover scuba diving. If you need short-term holiday scuba insurance, click here to go to DAN short-term diving insurance.
If your plans change, use our Booking Support form as soon as you can and include your booking reference and travel date.
We will always try to move your booking to another available date. Date changes are subject to availability and do not restart the original cancellation period.
Refunds and cancellation charges are explained in the Refund and Cancellation Policy and in any trip-specific terms provided before payment. The terms accepted for your confirmed booking continue to apply.
A trip may occasionally need to be changed, postponed or cancelled because of weather, sea conditions, safety, or a National Park or local authority decision.
If this happens, we will contact you as soon as reasonably possible and explain the options. If we cancel your trip, you can move to a suitable alternative date or receive a full refund. No cancellation, administration or bank charge will be deducted from that refund.
Please provide accurate hotel details, check the pickup time and location shown in your booking confirmation, and be ready at least 10 minutes early. This helps the transport team keep every collection running on time.
If you need help with your pickup on the morning of travel, contact the correct boat office directly on WhatsApp:
We work to keep trip descriptions, inclusions, prices and schedules accurate. Travel information can change, so your latest written booking confirmation takes priority where it differs from general website information.
Website text, photographs, branding and original material may not be copied or used commercially without permission.
Our Privacy Policy explains how booking and traveller information is used and retained. Our Cookie Policy explains the website technologies we use and the choices available to you.
We may update these terms when our booking process, trips or applicable requirements change. The version provided or linked when your booking is confirmed will apply to that booking unless a later change is agreed with you or is required by law.
