There are plenty of things to do on Green Island, whether you want to snorkel, see the reef without getting wet, walk through rainforest or spend a quiet hour on the beach. Don’t try to squeeze all ten into one visit. Choose one main reef activity, then add a walk, a swim or some beach time around it. This guide explains what each activity involves, who it suits and how day-trip packages handle the inclusions.

Snorkelling is the simplest way to get into the water and see the reef around Green Island. You can snorkel from the beach, take a boat to an offshore snorkel site or join a snorkel led by a marine biologist.
Beach entry gives you the most freedom because you are not tied to a set session. Use the patrolled swimming area and follow the lifeguards’ advice about where to enter the water. If snorkelling is the main reason for your visit, make the offshore boat trip your priority. A marine-biologist-led snorkel gives you guidance in the water and helps you understand what you are seeing.
Green Island packages handle inclusions differently. Some provide snorkel gear, some provide a glass-bottom boat tour, and some let you choose between them. Flotation vests, prescription masks and protective suits are also available through the island dive shop. Visibility and marine life vary from day to day, so no particular sighting is guaranteed.
A glass-bottom boat lets you look down into the reef while staying dry. The trip takes about 30 minutes, with crew commentary explaining the coral and marine life below the boat.
This is the easiest reef activity for non-swimmers, young children and groups with different levels of water confidence. You do not need to change clothes, carry equipment or enter the sea. There is still plenty of time for a walk or the beach afterwards.
Some Green Island day trips include the glass-bottom boat as the main reef activity. Others offer it as an optional extra. It is less demanding than snorkelling or diving, which is exactly what many mixed groups need.
The semi-submersible gives you a different dry view of the reef. Instead of looking down through the floor of a boat, you sit in an air-conditioned cabin below water level with viewing windows beside you. The crew provides commentary as the vessel moves past coral and fish.
Big Cat operates the semi-submersible at Green Island, and the ride lasts about 30 minutes. It is not included with every island trip. That side-on perspective feels more like looking out into the water than peering down from above.
One dry-viewing boat is enough for most day visitors. The glass-bottom boat is simple and easy to fit into the day. The semi-submersible gives you the below-water-level view without asking you to swim.
Seawalker lets you walk on the lagoon floor without learning to dive. A large helmet supplies air while guides stay in the water with you. There is no breathing equipment to operate, and you do not need to know how to swim. Your head stays dry, and glasses or contact lenses are both allowed.
The complete activity, including the safety briefing and time in the water, takes approximately 45–50 minutes. Put it in your plan rather than treating it as a last-minute extra.
Seawalker puts you on the seafloor without the training needed for scuba. You will still be fully in the water. Take the glass-bottom boat or semi-submersible instead if you want to stay completely dry.
Green Island offers introductory dives for beginners and guided dives for certified divers. An introductory session starts with a briefing and basic skills practice in the island pool. You then travel by dive tender to a reef site just offshore. Certified divers need to bring proof of certification.
Scuba takes more time and energy than the other reef activities, so give it the largest block in your plan. The pool practice and close supervision help a first-time diver learn the basics before heading offshore.
The minimum diving age is 12. You must disclose relevant medical conditions and medications before the dive because they can prevent participation. After one dive, allow 12 hours before travelling above 300 metres. After multiple dives, allow 24 hours. Keep those intervals in mind if you plan to fly or travel into the ranges after Green Island.
A shaded boardwalk crosses Green Island’s vine-thicket rainforest. Interpretive signs explain the plants, wildlife and island history along the way.
The walk is easy to add between water activities and does not need separate equipment or an activity ticket. It also gives non-swimmers an easy land-based activity away from the reef boats. Look around the trees and you may notice forest birds, insects and the change from coastal plants to denser rainforest.
The boardwalk is self-guided. Some Great Adventures trips also include a guided island walk with a marine biologist, but that walk is not part of every visit.
You do not need to book every hour on Green Island. Swimming, sitting under the trees and using the picnic areas do not require another activity ticket. The patrolled swimming area is on the northern side near the Beach Hire hut.
Kayaks, beach volleyball equipment, sun lounges and umbrellas are available as paid hire. Jet skis and other motorised watersports are not permitted in the Green Island locality.
Leave some open time here even on a full-day visit. Children get a break between organised activities, and the whole group gets time without another briefing or departure point.
Marineland Melanesia is a separate attraction on Green Island with crocodiles, aquariums and a private collection of Melanesian artefacts. Marineland offers a land-based break from swimming and reef boats.
Families with children who are interested in animals will get the most from this stop. The aquariums and cultural collection also break up a day otherwise centred on coral viewing and the beach.
Marineland requires separate admission. Give yourself time to see the aquarium and artefacts rather than squeezing the attraction between two booked water activities.
A 10-minute scenic helicopter flight shows the shape of Green Island and the scale of the surrounding reef in a way you cannot see from the beach. It fits alongside one main water activity without taking over the day.
This is a premium add-on, but it requires very little physical effort. You stay seated inside the aircraft while the island and reef open up below you.
Passenger weights and carry-on luggage must be supplied when booking because they affect the aircraft’s balance. The single-seat limit is 130 kilograms. Passengers above that limit require an additional seat under the operator’s conditions.
Parasailing lifts you above the water behind a boat, giving you an open-air view back towards Green Island and across the reef. You are not steering or swimming, but the height and movement are part of the activity.
Parasailing is the more exposed aerial experience. Choose the helicopter if you would rather stay inside the aircraft.
Participants must weigh at least 25 kilograms. Children aged 8 to 14 must ride with an adult.
Trying to complete all ten activities will turn your island visit into a rush between counters and briefings. Plan one main reef activity, one lighter land or dry activity and enough open time for lunch or the beach.
Choose one activity to build the visit around: snorkelling, the glass-bottom boat or the semi-submersible. Use the remaining time for the rainforest boardwalk or a quick swim.
Seawalker and scuba need briefings and set activity periods, so make either one the centre of the visit. Do not stack several other bookings around it. For ferry times, terminal details and package inclusions, see the Green Island transport guide.
A full day gives you room for one booked reef activity, one dry or land-based attraction and a relaxed break. For example, snorkel, walk the boardwalk before lunch and then spend time on the beach. A non-swimmer can replace snorkelling with the glass-bottom boat or semi-submersible.
Keep scuba or Seawalker as the main organised activity. Add one simple experience around it rather than filling every available session. The extra time is there to help you slow down, not to create a longer checklist.
Yes. Green Island is worth visiting when you want reef viewing, beach time and a short rainforest walk in one easy day. A mixed group can split between snorkelling and a dry reef boat without planning separate trips. If you want island time and an offshore reef in the same day, the Green Island and outer Great Barrier Reef day tour combines both. If your only goal is to spend as much time as possible offshore, choose an outer-reef tour instead.
Non-swimmers can take a glass-bottom boat or semi-submersible, walk the rainforest boardwalk, use the picnic areas, relax on the beach and visit Marineland Melanesia. Seawalker puts you on the lagoon floor without requiring swimming skills. It is still an in-water activity, so take a reef boat when you want to stay completely dry.
Start with a glass-bottom boat or semi-submersible if your children are not ready to snorkel or are not confident in the water. The beach and rainforest boardwalk are easy to add without another briefing or set departure. Scuba starts at age 12. Parasailing has a minimum weight of 25 kilograms, and children aged 8 to 14 must ride with an adult.
Yes. Green Island has a restaurant, café-style takeaway food and places serving drinks and snacks. Picnic areas are also available for day visitors. If you have booked activities with set times, plan lunch around them.
The rainforest boardwalk, beach, swimming area and picnic facilities do not need a separate activity ticket. You still need paid transport to reach Green Island. Day-trip inclusions differ: some provide snorkel equipment, some provide a glass-bottom boat, and some let you choose. Seawalker, scuba, the semi-submersible, Marineland, helicopter flights, parasailing and beach equipment hire are separate paid activities unless the package includes them.
