Snorkelling Vs. Scuba Diving

To summarise, snorkelling is easier and more accessible than scuba diving. But your ability to explore the reef is more limited. 

Scuba diving provides a more immersive and mind-blowing experience on the Great Barrier Reef. It’s also a more challenging adventure sport that has more age, health, and travel restrictions. So while it’s slightly more hassle and money to go scuba diving, it’s all worth it for the enhanced experience underwater. 

It’s all up to your personal preference!

Here are some more tips to help you decide whether to try snorkelling or scuba diving on the Great Barrier Reef

Snorkelling is better suited for families with young children. 

Scuba diving has a minimum age requirement of 12 years. So if you’re visiting Cairns with your young family, snorkelling is the better option. Young kids can snorkel with ease on the Great Barrier Reef, just make sure you check age restrictions on each individual tour as they might vary. But flotation devices will be provided, and an expert crew is always there to ensure every child feels safe in the water! 

You can also go snorkelling off beaches or in more shallow waters around the islands near Cairns. These areas can provide a more relaxed environment for kids, as opposed to the deeper waters of the Outer Reef.

Scuba diving is better suited for passionate explorers and thrill seekers. 

Snorkelling does allow you to observe the magical Great Barrier Reef, but it can only get you so far. Scuba diving does require more training and equipment, but that extra effort allows you to travel deeper into the ocean and see a whole new world. You can see massive coral structures and unique marine life that may not come all the way up to the surface. 

Having the ability to explore further underwater also lets you escape the crowds. You can venture to different places that snorkellers can’t get to, which means fewer people and more untouched nature.

Snorkelling is better suited to those short on time and money.

Because snorkelling requires less equipment and preparation than scuba diving, it’s overall more accessible. All you need is a mask, snorkel, and fins, and boats from Cairns can reach shallow snorkel sites in less time than travelling to the Outer Reef. So snorkel tours are cheaper than diving tours.

With less equipment, it’s also much quicker to just don your mask and hop off the boat for a snorkel. You can find convenient half-day trips from Cairns that include snorkelling on the Great Barrier Reef! If you want to see the reef on a budget or on a time crunch, snorkelling is the way to go.

Scuba diving is better for longer and more adventurous trips. 

If you do have more time and money to devote to your Great Barrier Reef trip, scuba diving provides an unforgettable experience in the water. While you won’t find many half-day trips that include diving, you still book a day trip that includes 2 or 3 dives at reef sites near Cairns. You just have to leave at least 12-24 hours after your dive before getting on a plane!

If you can spare more than one day, you can even spend multiple days at sea on a dive live-aboard! Whether you want to learn diving and get your certification onboard, or you’re an advanced diver looking for a week of epic dives on the Coral Sea, dive liveaboards are an incredible addition to any Cairns trip.

Summary of Snorkelling vs Scuba Diving in Cairns

Overall, both snorkelling and scuba diving are world-class in Cairns! The Great Barrier Reef lies right offshore, with both shallow fringing reefs off islands and deeper Outer Reef sites available for snorkellers and divers. You can even try both if your schedule allows!

Anyone who has tried scuba diving will likely say it’s well worth the extra effort and money. Scuba diving is a once-in-a-lifetime experience that lets you discover new parts of our planet. It’s truly surreal, and definitely worth trying at least once. 

But many travellers are perfectly content with snorkelling as well! It’s affordable, easy, and available to a wider range of people. Scuba diving can be limiting because of the age and health requirements. You can still see amazing corals and spot marine life on a snorkel tour. So consider your travel style, budget, and preferences to plan the underwater trip of your dreams in Cairns!
