Scuba Diving & Snorkelling: Things To Know Before You Go

Scuba diving and snorkelling holidays reveal the underwater world in unforgettable ways. This page shares things to know before you go — including experience levels, conditions, equipment and planning considerations for underwater travel.

Understanding the Difference Between Diving and Snorkelling

Snorkelling is generally accessible and low-impact, requiring minimal equipment and training. It allows you to observe marine life from the surface and suits a wide range of ages and confidence levels.

Scuba diving involves deeper exploration using specialist equipment and certification. Understanding which experience suits you — or combining both — helps ensure comfort, confidence and enjoyment throughout the holiday.


Certification, Experience & Comfort Levels

Certified divers benefit from structured training that builds confidence and awareness underwater. Different qualifications allow for different depths and conditions, which affects where and how you can dive.

Being honest about your experience level helps dive operators match you to suitable sites. Choosing dives within your comfort zone often leads to more relaxed, enjoyable underwater experiences.


Guided Dives, Schools & Operators

Reputable dive centres and snorkelling operators play a huge role in overall enjoyment. Experienced instructors and guides help with equipment setup, briefings and local knowledge.

Choosing well-reviewed operators with clear safety procedures allows you to focus on the experience rather than logistics. Good guidance often enhances confidence, especially in unfamiliar waters.


Marine Life, Reefs & Responsible Behaviour

Underwater environments are delicate ecosystems. Coral reefs and marine species can be easily damaged by careless contact or disturbance.

Respectful behaviour protects marine life and improves sightings. Calm movement, neutral buoyancy and observation from a distance often lead to more natural and rewarding encounters.


Conditions, Visibility & Timing

Water conditions vary by location and season. Visibility, currents and water temperature can all affect the experience, whether snorkelling or diving.

Researching seasonal conditions helps align expectations. Some travellers prefer calm, clear waters, while others enjoy richer marine activity at different times of year.


Equipment, Fit & Comfort

Comfortable, well-fitted equipment makes a noticeable difference underwater. Masks that seal properly, fins that fit well and exposure protection suited to water temperature improve enjoyment.

Clarifying what equipment is provided — and whether you can bring your own — helps you feel prepared. Familiar gear often increases confidence, especially for regular divers.


Health, Insurance & Medical Awareness

Scuba diving has specific medical considerations, including fitness declarations and surface-interval guidelines. Snorkelling is generally less demanding but still benefits from basic awareness.

Ensuring appropriate travel insurance and understanding dive-specific cover adds reassurance. Quiet preparation allows you to relax and enjoy the experience without distraction.


Pace, Rest & Enjoyment

Underwater activities are most enjoyable when balanced with rest. Diving schedules often include surface intervals, while snorkelling benefits from breaks between sessions.

Allowing time to recover, hydrate and reflect helps maintain comfort and focus. A relaxed pace often leads to better experiences both in and out of the water.
